6 DIY Trip Wire Alarms for Off-Grid Security

A lot of folks have never put together a trip wire alarm, and there’s a good reason. There are just not a lot of occasions where a trip wire is necessary. However, when those occasions do emerge, it’s at least worth understanding the concept of what works and what doesn’t.

What Exactly is a Trip Wire?

But who needs them now, do it yourself versus buy it yourself, trip wire 101, electrical wire, monofilament fishing line, bungee cord, lasers, infrared, and motion detectors, rocks in cans, firecracker poppers, .22-caliber blanks, air horns, sirens, and other noise makers, what about light, this is not about the use of lethal force, location, location, location, 1. bungee marbles, 2. monofilament on the rocks, 3. paracord pull-string fireworks, 4. thin wire .22-caliber blank, 5. winter white trip wire, 6. back gate avalanche, is this a good idea.

A trip wire is a long length of thin wire, monofilament fishing line, or any other type of cordage that is usually connected to something that makes noise. The idea is that when an intruder either human or animal steps into the wire, the alarm is sprung, alerting you to an intrusion.

The trip wire concept was developed in wartime as a way to alert troops of an enemy incursion. This was particularly needed at night and was often used in the dense island jungles during the war in the Pacific in World War II.

The usual configuration was a thin length of rope suspended low to the ground between trees with empty C-ration cans filled with stones to rattle the alarm whenever the wire was “tripped.” And while booby traps were sometimes used to maim or kill, there was always the concern that an innocent civilian or friendly soldier wandering off to go relieve himself would trip the wire.

The usual reason someone considers a trip wire is when they are in an area with the potential for any number of unknown threats. The idea is usually to make noise to signal an intruder .

The threat could be from wild animals like bears or wolves approaching a camp in a remote area.
In countries ravaged by civil wars and civil unrest, no night is safe and trip wires are sometimes used to at least alert the local population if a covert threat is approaching.
Following a disaster , many people find themselves isolated and alone with the potential for looters or worse. That’s when a trip wire may at least scare them off, if not serve as a warning of an unwelcome approach.
In times requiring a bug-out to a distant but safer location, there are occasions where a night must be spent on the road in unknown territory where the threat is equally mysterious. Trip wires would serve as a perimeter defense to at least alert anyone spending an unplanned night on the road of any approach.
And yes, they’re still used in war zones, although the technology of trip wires in those areas is usually defined by lasers, electronic signals, or infrared beams connected to electronic alerts through cameras or video or in extreme cases: explosives.
In fact, the concept of contemporary home security systems connected to motion-detector technology to turn on lights; sound an alarm, record video, or alert the local police are the 21 st century versions of the trip wire concept.

It may seem unnecessary to build your own trip wires when so many options appear on the Internet , but if a situation makes the Internet undependable or unavailable, or deliveries or the purchase of many things is difficult or impossible, that might be a good time to know how to improvise a trip wire.

There’s also the fact that in some instances, the electricity is out or unavailable, and most modern security solutions require at least some level of power. In a worst case scenario with a total grid failure, technology will quickly diminish and old-school, analog solutions will offer the most dependable options. Those are the types of trip wire concepts we’ll cover.

We might as well start with the wire. There are a variety of options . Usually, the wire or cord is low-profile and hard to see. It also needs to be relatively strong. If someone or something walks through the wire or cord and it easily breaks, little is accomplished except alerting the intruder to the fact that you’ve setup some trip wires.

Here are options to consider:

Electrical wire comes in a variety of gauges, but the smallest (and most inexpensive) gauges are referred to as 14 and 16 gauge. They’re more than strong enough to serve as a trip wire.

They’re all coated with a flexible plastic coating that comes in a range of colors. White, black, red, and green are the most common, and those colors present camouflaged, stealth characteristics, depending on the time of year, time of day, and natural surroundings. Floral wire is another option and also comes in a variety of colors.

Fishing line is thin, strong, and also hard to see. Buy one of the heavier weight tests of at least 50 pounds or more. Avoid any of the brightly colored lines. Go with a neutral, plain monofilament.

Paracord is another surprisingly strong option, but you have to think about the color of the cord. During winter, a white Paracord might makes sense if the ground is snow covered. A green or camo cord could work well in a forest or field. Black is an obvious choice for night.

You don’t see bungee cord mentioned in a lot of the write-ups about trip wires, but it has a characteristic that could make sense if you think about it. If the idea of your trip wire is to rattle a bell, cans, or other noise maker, a bungee cord will certainly make that happen.

In fact, a bungee cord may cause more noise to occur than any of the other options we’ve mentioned due to its flexibility and springiness. A black bungee makes sense. Green if you’re in the woods.

If your trip wire is designed to trigger a mechanism, bungee is not the best choice, but if you’re rattling cans the old-fashioned way, it’s a good option.

You can buy these things and improvise a trip wire yourself, but make sure they’re battery or solar powered or have a way to recharge the batteries . These are complicated solutions, so we’ll mention them but we’re not going to spend a lot of time covering ways to make technology work in a primitive environment.

Some websites offer tips and solutions to improvising trip wires with technology, but it’s a lot of work and you have to consider how and when you’ll need any trip wire, and for how long.

The idea of most trip wires is to make a lot of noise when someone trips over the wire. Noise makers vary depending on what you have available or may have bought in advance. We’re going to assume your situation caught you a bit by surprise and that you have to improvise from available materials.

It’s believable that a lot of us would have wire, cords, and fishing line lying, around but things that make noise require a bit of creativity or at least some pre-planning , especially if you require a very loud alarm.

How loud your alarm needs to be depends on your distance from the trip wire and whether you are inside or outside. Someone camping in a tent will be more likely to hear a rattle of rocks in a can than someone sleeping in their home or cabin.

If you are at a distance from your trip wire or indoors, you may need to plan and buy ahead to acquire louder alarms like blank cartridge firing mechanisms, firecracker poppers, air horns, or anything else that will be heard under most circumstances.

And if you can, paint your alarms to match the environment. If you don’t have paint, you can rub some mud or clay on the bell/can/noisemaker so it is somewhat camouflaged. Black is good at night, camo combos for any natural forest or field, and snow white for winter.

If you’re trying to keep animals at bay, the colors are less of an issue. Animals only see in black and white, but keep an eye on the contrast. They can still notice highly contrasting shades.

A lot of us have bells around for various reasons including cowbells, Christmas bells, antique bells, and collectible bells. And then some of us don’t. If you have any assortment of bells, you’re off to a good start with a trip wire.

Even if you’re not a bell collector, there’s a good chance you have access to tin cans and rocks. No rocks? Anything that makes noise in a can will do from bolts to nuts or better yet, marbles— although marbles may jostle around in your can in the wind, so maybe stick with the pebbles.

You only want a few in the can but enough to make noise when the can is jostled. Smooth, rounded stones and marbles are best. Look for rounded stones in river and creek beds.

Drop a few in and give the can a shake. Adjust until you think you have the most and best noise for a shake. And if you don’t think a rattling can is going to work, then you’ll need to think about stocking some very loud alarms like the next few items.

There’s a type of firework that has two stings emerging from either end of a firecracker. When you pull the stings, the firecracker pops. They’re loud, and you can tie them onto a number of trip wires around your area.

Some of them are made out of paper and will get wet due to rain, snow, or morning dew, so wrap them in plastic cut from a black or neutral garbage bag. They’ll most likely scare off a wild animal and might scare off an intruder. Either way you’ll certainly hear it.

This isn’t about setting up a full loaded .22 caliber round on a trip wire. That’s a really bad idea. Trip wires are indiscriminate and when tripped, the wire fires. Most .22-caliber blanks are used for nail hammers to drive nails and pins into concrete.

The firing mechanism for trip wires and .22 blanks can be bought online , although the blanks are available at most hardware stores next to the nail guns . There are also 12-gauge blank variations on this concept.

As a trip wire, they’re mostly designed to deter wild animals, but the people who sell them offer all sorts of reasons to use them . You’ll certainly hear it, and it will scare most anyone and anything away.

However, it may cause a response you don’t necessarily want. If someone is approaching and they are armed, they may perceive the detonation of a .22-caliber blank round as actual gunfire and return fire. Up to you.

If it makes noise, it’ll work on a trip wire. The only challenge is figuring out how to trigger the noise. Things like sirens need power, but if you’re handy with a little wiring, you can make a trip-switch to set off the siren.

There are also solar powered options available . There’s some advice out there about setting up a rock over an a ir horn that will fall on the air horn button when tripped. That requires some precise setup and once that rock is on the air horn, it’s going to make a lot of noise until you lift the rock.

You’ll also probably use up all the air in the horn by the time you get out of bed or your sleeping bag to lift the rock.

There are solar powered motion detectors that will illuminate an area. These are best hung high in a tree out of sight and out of reach. It’s a variation on the trip wire concept, and it’s usually used to dissuade animals. It could also deter an intruder, but if you’re using something to trip an alarm that will notify you of an intrusion, a light in the night will do little good if you don’t see it while you’re sleeping or otherwise occupied.

Most trip wire concepts are designed to make noise to let you know that someone or something is approaching, and improvising a light to a trip wire can get a little complicated unless you have some good skills with wiring and trip switches. We’re going to skip the lights and stick with noise.

Booby traps have often been used in times of war and they are designed to kill. That’s a really bad idea. The whole idea is to either scare something or someone away with sound or to at least be alerted to the presence of something approaching.

Even a blank .22-caliber cartridge should be pointed towards the ground. Otherwise, the blast could send shrapnel from a tree trunk or branch in someone’s direction, and you don’t want it to be one of your children or an innocent wanderer lost in the night. This is about making noise, not war .

Where you place any trip wire is as important as the design of the trip wire itself. You want it far enough away to give yourself some time to observe the direction of the alarm and see what’s coming plus prepare to respond. But you also want it close enough so you can hear it.

Another location factor is the height of the trip wire from the ground. If you’re concerned about human intruders or large animals like a bear , you’ll want your trip wire about a foot above the ground. 6-inches above the ground is about the minimum or someone or something could step on the wire without tripping it.

Also, if it’s any lower than 6 inches, every random squirrel, raccoon, possum or most any other rodent could trip your wire repeatedly. If that happens enough, you may take to ignoring the trip wire noise while assuming it’s just another passing rabbit when it’s the intruder you were so worried about in the first place.

Support for attaching a trip wire is something else to think about. A lot depends on what’s available at the location and what kind of trip wire you’re using. Two tree trunks could work, but they will create a very taut trip wire that may not ring any bells for long. They could also cause an intruder to literally trip which may be an effective deterrent–or not.

The branches of two trees or two saplings give some flexibility to any trip wire and could result in a sway in the wire, causing the noise to persist a little longer.

Two stakes in the ground are another solution, but if you’re trying to raise your trip wire to a foot of height, you’ll need long and large stakes deeply imbedded in the ground.

The number of trip wires you set up is another location consideration. Think in terms of avenues of approach. Around a home or dwelling, any open area like a gap in a fence, a gate, an open back or front yard, approaches to doors or windows, or approaches to outbuildings are worth thinking about.

A lot depends on what you’re worried about, the location, and the immediate threat level.

A remote survival camp or any campsite for that matter might require a number of trip wire setups, but even then –animals prefer open paths and clear terrain. A human intruder may do otherwise and stick to the cover of scrub, brush, and trees, so you just have to do your best to estimate what could be coming and from where.

Check your trip wires if you have them in place for any length of time. Improvising an alarm with some rocks in a can is a good idea, at least until it rains or freezes and the water or frozen rocks in the can fail to rattle.

It’s also possible one of your trips has worked loose; been tripped without you knowing it, and loose on the ground, or something as simple as a knot that has worked loose. It’s actually somewhat of a “set it and forget it” approach, but it’s worth checking them from time to time if you need them for any duration.

Remove your trip wires when you don’t need them anymore or when you move on. They will cause you or anyone else to trip, including family members, as long as they’re in place. You also may need them again.

The DIY Trip wires

The advantage of a bungee cord as a trip wire is its springiness. Think of it as a rubber band on steroids. In fact, the interior of a bungee cord is just that. Long strands of rubber encased in a flexible fabric braid.

You can attach anything that makes noise to a bungee cord. The advantage is that a bungee will rattle and shake longer while making more noise.

Bungee cord of sufficient length for your trip wire area. You can buy coiled bungee cord in various colors and cut them to length. If you only have packaged bungee cords of varying lengths with hooks, you can connect them together, although the hooks will be somewhat visible during the day.
Various soup cans painted to match the terrain or time of day. They should also have holes punched towards the top of the can on either side.

(You can substitute bells for the cans.)
Choose a bungee cord color that you think will blend in the best with the surrounding areas.
Wrap the one end of the bungee around a tree trunk, branch, sapling or stake. Tie it off with two half-hitches and pull tight.
Thread your can or cans onto the bungee.
Stretch it tight to another tree trunk, branch, sapling or stake and wrap and knot with two half hitches until tightened.

Add marbles to the can and test it with a few pulls on the bungee. Add or remove marbles depending on the sound.
Test your bungee trip wire again with someone in camp or in the house and ask them if they can hear the cans? If not, move the trip wire closer or add some more cans.

Monofilament is an excellent trip wire source. It’s hard to see during the day and totally invisible at night. The key is to have a strong enough weight test to activate the noise without breaking. It can be used in most any trip wire setup in any location.

Monofilament fishing line. 50 pound test or higher is best, but any weight test will do if it’s all you have on hand. You could even double or triple up the monofilament if you’re worried it will break or snap.
Empty tin cans. Soup cans are a good size. Peel off any colorful labels and either paint them or coat them in a thin film of mud so they are less reflective. Paint the cans black or do a camo pattern depending on the surrounding area.
Smooth, round rocks, nuts, bolts, marbles —anything hard that can easily move around and rattle in the can.
Cordage or wire to attach the cans to the monofilament.
Wrap the one end of the monofilament around a tree trunk, branch, sapling or stake. Tie it off with an improved clinch knot (a fishing knot perfectly suited to monofilament) and pull tight.
Punch 4 holes in each can.

The holes should be punched in pairs towards the top of the can about a ½ inch apart and opposite each other at the rim of the can. This is so the can is bound tight to the monofilament as it is threaded through the holes to ensure a good shake.

Thread the monofilament through the holes.

Add the can or cans along the monofilament, but try to place them in spots that are obscured by brush, tall grass, or other natural camouflage. It makes no difference at night, but take a look when it’s dark to be sure.
Stretch it tight to another tree trunk, branch, sapling, or stake and wrap and knot with another improved clinch knot and pull light.
Try to locate the cans in a location that is hard to see during the day.
Drop a few rocks in the can and shake the fishing line wire to see if the cans rattle. Add more or less rocks until the cans make a racket. Continue to add cans where you can. Tighten the cans to the monofilament if you need to.
Test your monofilament trip wire and have someone in camp listen and ask them if they can hear the cans. If not, move the trip wire closer or add more cans.
Thin paracord . A type I or type II is thin enough to be obscure but strong enough to function as a trip wire. Choose the color that best matches the terrain and time of day.
Pull-string fireworks. They’re legal to buy in most states and can also be purchased online. You’ll need to have them on hand because they’re very difficult to improvise.
Choose a paracord color that will blend in with the surrounding area.
Wrap the one end of the paracord around a tree trunk, branch, sapling, or stake.
Find a location that is hard to see along the paracord and tie one end of the pull-string firecracker to the cord.
Tie the other end of the paracord to another tree trunk, branch, sapling, or stake and wrap and knot with two half hitches until tightened.
Carefully tie the paracord to the other end of the pull-string using a square knot or any knot you can improvise. You have to do this delicately. You want the paracord tight, but you don’t want to accidentally detonate the firecracker. If you want to get the best tight line, you could tie the final end of the paracord to the tree or stake with a trucker’s hitch . This will give you a little more control over the slack, but be gentle.
You don’t want to test your popper trip wire or you’ll have to retie another one. If you want to test the distance and whether or not you’ll hear it, have someone in camp or in the house listen while you pull a spare popper. If they don’t hear it, move the trip wire closer. Don’t be tempted to add multiple poppers to the same trip wire. What will most likely happen is that one popper will trip, leaving any others unexploded.
Unlike bells and tin cans, you have to rearm your firecracker trip wire whenever it goes off. That’s not a bad idea to at least see if there are any footprints or paw prints to tell you if your intruder was human or a stray dog.

Floral wire . Black is the default color, but if you have a green or white color that can match the terrain or time of year (snow), that’s a good idea.
A .22-gauge firing capsule. You can buy these online. They’re hard to find in stores.
Blank .22-gauge loads. Buy these online where you bought your firing capsule or at a hardware store in the nail bun aisle.
Wrap the one end of the wire around a tree trunk, branch, sapling or stake. Choose a color that matches best with the surroundings.
Attach an unloaded .22-gauge capsule in an obscure spot.
Attach the other end of the wire to the .22-gauge firing capsule.
Stretch it to another tree trunk, branch, sapling or stake and pull until you have tension on the .22-gauge firing mechanism.
Test the unloaded .22-gauge capsule by pushing on the trip wire to see if the pin fires. If not, adjust the tension. If the pin fires, rearm the firing mechanism and carefully add a blank .22-gauge cartridge.
If appropriate to the situation, do a test. It will be loud and attract a lot of attention. If the firing pin is firing when unloaded, you should be good to go if a test causes local problems or concerns. Anything that sounds like a gun shot in the neighborhood may attract some unwanted attention.

This setup uses a white length of electrical wire attached with overlapping loops through two holes in the top of a can painted white. Obviously, it’s a winter trip wire and it uses marbles or pebbles to create the alarm. The overlap of the wires causes the can to shake and rattle more than a conventional wire or line passing through the holes.

White electrical wire
A can or cans painted white
Marbles or pebbles

Directions:

Attach one end of the wire to a tree branch.
Run the wire through the can in a discreet location, but overlap the wires so the can shakes when the wire is tripped.

Attach the other end of the wire to a branch and test.

If trouble is close to home and you need to come up with a trip wire fast, this is one option. This is a trip wire connected to a gate, causing an avalanche of large rocks to fall onto a large piece of sheet metal or even a metal garbage can. It makes a lot of noise and can also be staged so the rocks fall onto the metal when the gate is pushed rather than pulled open.

You can improvise this kind of setup anywhere someone may enter uninvited, from a barn door to a back door to a door on a wood shed. This is not a stealthy trip wire. It assumes that a gate or other barrier is obstructing any view of the setup.

Bucket to hold the ro cks.
About two dozen large rocks from 1 to 2-inches in diameter.
A large metal surface or object that will make a lot of noise when rocks land on it. Sheet metal, metal garbage cans, metal ductwork, any type of metal that’s relatively thin and will create noise.
A wood platform 12” square to support the bucket
Three wooden dowels about 3 feet long. (You can use old broom handles or even 1×2’s can work).
Cordage . Any type and any color. The trip wire will also be obscured by the gate or barrier.
Fill your bucket with your rocks and dump them on your metal sheet, can or whatever else your using to assess the noise. Ask someone inside your home or camp to determine if they can hear it.
If you’re satisfied with the noise level, fill the bucket with your rocks.
Pound the 3 support sticks into the ground in a triangle that will support the 12” square platform.
Set the 12” platform on top of the support sticks. You don’t want to drive the support sticks too deep into the ground. You want this to be a precarious balancing act.
You have two options. If your gate pulls open towards you, attach your trip wire to the gate and to the front support stick or your three sticks setup far enough away to allow the rocks to fall on the metal. Place the metal in the best location for the rocks to fall. You might want to put some rocks under the metal to lift it off the ground to increase the noise and hold it in place to some degree. When the gate is opened, the trip wire will pull out the support and the bucket will fall forward onto the metal.
If your gate opens away from you, set up the support sticks and the platform right next to the gate. When someone pushes the gate open, it will topple the bucket with the rocks onto your metal plate or can.
Test either option to see where the rocks fall and place your metal sheet or container in that location.
Test again and ask someone inside the house to assess the noise level.
If satisfied, set the trip or add more rocks or adjust the metal location or type of metal. It’s an easy set up and will create enough noise to cause most intruders to jump out of their boots.

Are There Other Approaches?

No doubt . Trip wires have been around a long time, and what you choose to improvise is only limited by your imagination and materials on hand . What we tried to do here was explore the concept so anyone could take the basic idea and adapt it to their needs, available supplies , and their location. It’s all a question of finding stuff that will make a lot of noise when someone trips over your wire.

In an emergency, it’s good to know how to do this stuff. In an ideal scenario, you would have sophisticated electronic devices that are solar powered and connected to motion detectors and all manner of alerts and alarms. Complicating things further is that any device with any level of electronics will also need to be weatherproof.

But this isn’t about an ideal scenario with a house surrounded by lasers . It’s about a sudden and surprising time when things rapidly become dangerous or threatening. Anyone in that situation would have plenty to think about and the ability to quickly improvise something as basic as perimeter alarms with trip wires not only makes sense but simply seems like a good idea. Just don’t throw way any old bells.

Our research narrowed the field down to a few brands and types of alarms that we compared with various gauges and loudness: Fith Ops, Trip Alarm Co, Remfly, ASR, BASU, Fast Guard, Camp Guardian, and more.

You can see our full list of review criteria below in the What to Look For section, with an explanation for each.

We considered a wide range of alarms ranging from traditional blanks to electronic ones. Although our results seem one-sided, performance spoke for itself after extensive testing. We quit looking at many of the temporary films since we were looking for permanent security and safety enhancements.

We’re always looking for new and better supplies, so if you have a trip wire alarm that you trust, let us know in the comments. We review most of our tested supplies annually so we can try to get it in the next roundup round and see if it will beat out our top picks.

The best trip wire alarms have a few features to look for:

Noise Level

Size & weight, versatility.

When you get the right blend of these, you can find an alarm that will alert you in a wide range of situations. Below, we break down what each of these features means for the alarms that truly set themselves apart.

Value: Cost vs. Benefit

The amount of money you spend on something as niche as a tripwire alarm shouldn’t blow out your entire budget. There is a wide range of prices depending on the features you are looking for, so it shouldn’t be too problematic if you just stick to a plan. If it’s not likely that you’ll use the alarm in a practical setting, there is no need to pick one up if it’s beyond your budget.

You never want to spend too much money on one resource when it comes to security. It’s better to diversify your spending to make sure you are covered for a wide range of scenarios.

Not much point to an alarm if you can’t hear it. Sure, there are silent alarms that can notify you or blink a lot for you, but those have niche applications.

We want our perimeter alarms to be LOUD and deter whatever animal is coming through or let us know anywhere on our property of an intruder.

Depending on the ambient noise in your area, 120-130 dB should be heard up to a mile away. When you go below that you are hampering the potential distance and effectiveness of the alarm.

Most trip wire alarms are set up outdoors. This means they’ll need to be able to handle the elements.

Aluminum rust-proof designs are popular because they can be machined easily and accurately with less weight.

Size and weight shouldn’t hold you back if you plan to keep the alarm in a mobile kit or bring it with you camping. Most tripwire alarms are lightweight, being at or less than an ounce.

You’ll also need to account for the ammo and the wire itself since it is part of an alarm system and not as useful on its own.

Tripwire alarms and remarkably versatile. You can set perimeters in any conditions or areas to alert to incoming vehicles, intruders, or animals. They can also be used to signal for help or for communication within your group.

The basic components of a trip wire alarm are the firing pin, the pull pin that trips the alarm, and a detent to hold the charges. While we certainly don’t condone it, these can easily be worked into flare launchers or to use other ammunition. There are many reports of homemade firearms being made with these, though those are certainly dangerous and probably illegal in most places. (See our sources and references )

Tripwire alarms are relatively simple to set up but can be dangerous if done improperly. In Europe and Russia, there have been many documented cases of tripwire alarms being converted into homemade firearms. They have a firing mechanism (pull pin), a firing pin, and a detent to hold a wide range of rounds.

Warning : Using live ammo, or any unintended ammunition (like flares) can be extremely dangerous in a trip wire alarm, regardless of whether it is unattended. Even with blanks you should practice firearm safety and avoid pointing the business end at people. Do not set the trap until you are ready for it to be live- anticipate accidental discharge.

Here are the quick and easy steps to setting a tripwire alarm:

Pick a Spot – Pick a site where the approach fits a tripwire well, and possibly obscures the wire so it is easier to hide. You will need a solid mounting point for the alarm itself.
Mount – Mount your alarm securely using zip ties or screws. Make sure it is not visible from the approach side. Be sure to not load it yet.
Set Perimeter – Run your tripwire from the alarm across the perimeter approach line. Depending on whether you are using USGS tripwire or fishing line, there is some difference in how far you can run the line.
Set Alarm – Pull the firing pin ring, set the pull pin, and tie the perimeter line to the alarm.
Load Alarm – Always load the alarm last. No reason to misfire as you are setting it up.

Lastly, have a plan for when the alarm goes off. Being alarmed without a plan of action won’t do you much good.

Nate Polson (Canadian Prepper) has a solid video showing how to use trip wire alarms:

Tripwire alarms are by no means necessary for survival, but they are a convenient tool to have in a wide range of situations. For the size, weight, and price, there is very little drawback to having one available. Because it isn’t essential, you won’t find it on many of our checklists.

If you are running snare wire (or trip wire) in your kits- which is on many of our checklists , you should definitely consider adding an alarm to go along beside it.

Tripwire itself is remarkably versatile and we have a whole guide recommending the best snare or trip wire for your kits.

12 Gauge Trip Wire Alarm For Added Camping Protection

The allure of camping lies not only in the freedom of escaping the hustle and bustle of modern life but also in embracing the primal connection with nature. However, amidst the tranquility and beauty, it’s crucial to prioritize safety, especially when venturing into remote or unfamiliar wild camping places.

Installing a 12 gauge trip wire alarm around your camping site is a simple but effective solution. This almost invisible security system will notify you when an intruder or animal enters your site, allowing you time to secure yourself or escape to a safe area.

You can set up this easy warning system if you have an hour to spare and less than $50. It gives valuable peace of mind. Survival is ultimately determined by your ability to protect yourself and your family. A 12-gauge trip wire alarm ensures you are aware and prepared for anything coming your way.

Table of Contents

What Is a 12 Gauge Trip Wire?

A 12-gauge trip wire is a type of booby trap or alarm system typically used for security purposes. It consists of a wire or cord stretched across a specific area and connected to a triggering mechanism. When the wire is tripped or disturbed, the mechanism is activated, setting off an alarm or triggering another action.

How Does a 12-Gauge Trip Wire Work?

The .12 Gauge Trip Wire Alarm is a simple, yet effective camping tool designed to enhance security and safety in the great outdoors. The device operates on a basic principle: a tripwire mechanism connected to a 12-gauge shotgun shell. When activated, the tripwire is stretched across a designated path or around a specific area, and if triggered by any movement, it releases the firing pin on the shotgun shell. This, in turn, causes the shell to discharge with a loud and attention-grabbing bang.

The primary function of the .12 Gauge Trip Wire Alarm is to alert campers of potential threats or intruders, providing an audible warning that can deter animals or signal the presence of unwanted visitors.

While not intended to cause harm , its startling noise can startle and discourage approaching animals or potential intruders, creating a safe perimeter around the campsite. Due to its simplicity and ease of use, this camping essential has become a popular choice for those seeking an added layer of protection during their outdoor adventures.

Understanding Wildlife Signs

A 12-gauge trip wire alarm may save your life when you’re out in the bush. Paying attention to animal signs in the area can help you assess whether you need to set up an alarm for your protection.

When animals roam, forage, and hunt, they leave traces of their activities behind. Tracks, scat, fur, nests, or dens are all things to look for. Large predators like bears and mountain lions will leave their imprint. An alert system is strongly suggested if you see these carnivores near your campground.

Tracks provide a variety of data. Determine the species by looking at the size, quantity, and pattern. Bears , for example, have five toes and a unique heel pad pattern. Mountain lion footprints contain five toes as well. However, they are asymmetrical in design. The more recent the animal went through, the fresher the tracks. Cubs or a group of animals may leave traces in the same direction.

Scats or droppings may also provide information about the kind of animals that live in the region. Bear scat contains a lot of plant stuff, such as berries, nuts, and grass. Mountain lion scats are often found with hair and bone pieces from their victim. Scat signifies a territory or hunting zone, so be aware.

Another sign to look out for is hair caught on trees or plants. When most animals travel through thick vegetation, they leave hair behind. Check the color, length, and texture to see whether it’s from a bear, mountain lion, or other species.

If you see these signs near your camp, immediately install a trip wire alarm system around the perimeter. It might save you from falling victim to another beast all night. Your safety depends on being aware of the animal signs near you. Don’t ignore the advice; instead, behave responsibly. When trekking into the wilderness, a 12-gauge trip wire alarm may be your greatest protection.

Choosing a strategic tent position.

It is vital to your safety and security to put your tent in an optimal spot. In case of danger, you want a defensive site with excellent visibility and several escape routes.

Find Natural Protection

Look for natural barriers such as thick bushes, fallen trees, huge rocks, or steep slopes that are a barrier between you and any dangers. Ensure the place has adequate visibility so that anybody arriving from a distance can be seen. Before assembling your tent , clear the trash area and ensure there is no evidence of recent flooding.

Avoid Obvious Areas (if needed)

Avoid regular campgrounds, trails, highways, and other apparent locations where people frequently travel or meet. These spots are more accessible, and you are more likely to be seen. If you want to be undetected, you should travel somewhere distant. Find a clean area that humans haven’t disturbed in a dense bush or woodland.

Have Multiple Escape Routes

You’ll want options for getting away fast if you’re in danger. Choose a location that has at least two or three potential escape routes. Look for wildlife trails, shallow stream beds, or other natural routes that allow you to get in and out of the area easily, clear significant barriers from these paths so you may leave quickly if necessary.

Elevation Is Key

Higher land is easy to defend because you can view the surrounding region and notice potential risks from a distance. Look for a naturally high spot, such as a rocky outcrop, hilltop, or ridge.

Check that any higher land nearby doesn’t block your vision or give shelter for someone trying to sneak up on you. Without natural heights, you may build a raised platform for your tent out of garbage, logs, rocks, or other items.

Consider The Season

The season also plays a factor in selecting an appropriate tent location. Avoid low-lying places that may flood or become muddy if there is substantial rain in the spring or autumn.

In the winter, search for a site out of the wind and elements with natural tree cover or a wind-blocking barrier, such as a huge rock. Find a site with lots of shade in the summer to prevent sweating throughout the day.

Choose a tent site with care and planning for your own protection. Consider natural protection, avoiding visible spots, having numerous escape routes, gaining high ground if feasible, and considering seasonal factors. Take the time to choose the best strategic site for your tent.

Wildlife Safety Measures

Wildlife protection is critical to the well-being of both people and animals. Consider the following crucial measures:

Properly storing food and fragrant things: Keeping food and aromatic goods helps keep animals away from your campground. Use airtight containers or bear-resistant canisters to keep food, toiletries, and other aromatic things.

Bear canisters and bear-resistant sacks for hanging food: When camping in regions where bears or other animals may be drawn to food, hang your food high in trees or use bear-resistant canisters. This keeps the food safe and out of reach of animals.

Using bear spray and understanding how to use it: Bear spray is a very efficient deterrent against bear encounters. Carry bear spray in a convenient position and learn how to use it correctly. You should read the manual and practice using it before needing it.

Keeping your campground clean helps avoid attracting animals: It is important to keep your campground clean to avoid attracting animals. Clean cooking equipment and surfaces, remove the garbage and don’t leave food crumbs about.

Making a sound to warn animals of your presence: Making noise when trekking or moving through places renowned for wildlife presence might help notify animals of your presence, minimizing the risk of being surprised by them. This may be done by conversation, singing, clapping, or bells.

What's A Trip Wire Alarm And How Can I Make One?

Link Copied

Thread going through the eye of a needle. Set up as a trip wire.

I remember as a kid, my little brother used to love playing tricks on me. One of his favorite shenanigans was to hide in a corner quietly and wait for me, the unassuming sister, to cross his path. When I did, he'd jump out and lay down in front of me quickly, causing me to tumble to the ground and start crying. He called his little game, "Tripper". Needless to say, I hated it.

So what does this little anecdote have to do with a trip wire alarm system? Honestly, more than you'd think. My brother had figured out a system (albeit using his body rather than a real wire) that has been around for over a hundred years now. He was using his body to topple me over, thus incapacitating me and making it difficult for me to get up right after I fell. All he was missing was an alarm. Although he probably didn’t want an alarm, or he would have gotten in trouble with mom.

You are probably familiar with the term “trip wire.” These simple mechanisms have been used in wartime, in hunting traps, and in security systems. The basic idea is to have something, usually, a wire (although, as you will see later, lasers can be used as well) stretched out across a path or doorway, Trip wires are attached to two fixed points, such as fence posts or trees. The tripwire should be firmly fixed in place, so that it is taut enough to trigger when a person or animal trips over it, or causes it to move at all.

The earliest trip wire systems were attached to bells instead of a modern alarm. When the wire triggered, it would pull on the bell, causing it to ring and notifying anyone nearby that intruders were in the area. These systems were also used to set off bombs when enemies encroached on home territory during WWI. Enemies approached, activated the tripwire and caused the firing pin to lose tension and go off. Despite the incredible damage these bombs did, the system was undeniably elegant. This system was also used to trigger an attack alarm, notifying soldiers to be ready to fight.

Make sure you have a two anchor points, fishing line, and a bell. More instructions in the infographic.

Trip wire alarms today

Today, trip wire alarms are much more technologically advanced. Many systems incorporate laser technology that will sound an alarm if someone were to step across the laser. That’s right, you read that correctly. Lasers. Not exactly like the rotating lasers in Get Smart or the James Bond films, because these laser systems are invisible. No glowy red lines crisscrossing all over your yard and house, just simple, understated, invisible technology.

This kind of technology has a couple of advantages:

While burglars or intruders may be a little bit less likely to run away if they can’t see the tripwire, police can be notified without their knowledge, making it easier for police to catch potential trespassers or intruders.

Invisible lasers , unlike wires, are much harder to find and disable than a more archaic trip wire alarm system

Let’s be honest, it’s pretty cool that laser technology is becoming a relevant part of home security. Technological upgrades like this mean that these kinds of alarm can be wireless and much more aesthetically pleasing.

A Wall of laser lights outside in the city.

So how do laser trip wire alarms work, exactly?

Well, there are a few different components. Obviously, there are your lasers. These are created using a laser diode (a mechanism by which laser beams are produced) reflected against a light sensor. These are hooked up to a circuit board of some kind, which then talks to a computer that has been coded to do an action (whether that is to sound a buzzer, to call the police, to lock the doors, or all three). When the beam of the laser is broken, a switch will flip on the circuit board, which will then trigger the computerized response, notifying you of any intruders in the area.

Who is this technology for?

There are many uses for tripwire alarms. Most often, you’d think of them in relation to home security. A tripwire system can make for a great perimeter alarm around your home.

There are also some fairly easy do-it-yourself alarm systems that you can put up just about anywhere. YouTube is full of DIY project tutorials on how to make simple tripwire systems out of a laser pointer. These simpler systems will require a battery to power them unless you want to plug them in. They are created by setting up the laser pointer and reflecting it against a light sensor. This sensor is hooked up to a circuit board of some kind, which then tells the computer that has been coded to do something (whether that is to sound a buzzer or to send you a text message). When the beam of the laser pointer is broken, (the equivalent of someone tripping over a wire) a switch will flip on the circuit board, which will then trigger the computerized response, notifying you of any intruders in the area.

The possibilities for these are endless. If you’re in a college dorm, and you suspect that your roommates are stealing your food, set up a device in the cupboard with your food. You’ll be able to catch them in the act (I fantasized about this as a freshman). Hackaday.com offers an alternative possibility: installing one in your office space so that if someone walks in, you can act distracted. If you’re a hunter, it wouldn’t be too hard to set one of these up as a trap. Below is a video of one way to make a trip wire alarm.

DIY trip wire alarm with fishing line

If you don’t want a tripwire alarm that’s quite as technologically advanced as a laser-run system, or you don’t trust yourself to be able to code a circuit board to do what you need, you can fashion your own tripwire alarm out of some very simple elements, including fishing line, some kind of lever, and a bell or alarm.

The first thing you will need to do to set up your simple tripwire is locate the area in which you hope to set up your system. This should be in an area that you feel is vulnerable, or an area through which, you are worried that an intruder might be able to access your home. You need to have two anchor points. These points could be trees, bushes, lawn light fixtures , or for a much better system, you could use hidden stakes that you drive into the ground. Next you will stretch the fishing line tautly between the two anchor points. On one side, you will need to tie the fishing line around the stake. On the other side you will twist the line around the stake, and you can tie it as well, but be sure not to cut the line, as you will be running the line up to a bell that you anchor in a tree near a window, or on the window ledge itself. Make sure the bell is loud enough that you will be able to hear it from inside your house.

Once you have anchored the bell in place, you will tie the fishing line right above the bulge at the top of the bell. Your system is complete! Before you leave it, though, you should test it out. You will want to apply some pressure to the line. If you hear the bell ring loudly, your system should work great. If the bell only rings faintly, you will need to pull the line more taut. This should ensure that the bell rings loudly. Alternatively, you can attach the line directly to the clapper and see if that produces a louder noise.

This kind of alarm will go off no matter who crosses it, be it animal or human. If possible, you should run the line at knee-level, so many animals will be able to scamper under the line without triggering the alarm.

What are some other cool home security devices?

Laser security systems, while cool, are not the only way that you can protect your property from unwelcome visitors. Other gadgets are available as well. If you're a DIY kind of person, you might want to take a look at some of Cove's DIY home security system products . The idea behind Cove is simple: to enable you to install your own security system, using quality products for a great price.

Some of these products include:

Central Control Panel : Cove's central control panel is the brain of the system. From this panel, you can arm and disarm the system, contact security personnel, and often also notify the authorities of any medical emergencies. It's easy to use, easy to install, and (especially great for the current climate) requires no interaction with any door-to-door salesmen. Social distancing, people!
Security Cameras : These can be placed in many locations throughout your home, whether that be above your door or in your hallway. These will track who is in your house, and some can be set to run only when you are not at home. Cove's security cameras are especially great because they are backed up to the cloud, rather than to an SD card or similar technology.
Motion Detectors : The name is fairly self-explanatory. These track movement and notify you of any human motion on your property. They are actually pretty similar to the laser alarms in this way.
Window Sensors : A common point of entry for trespassers and burglars can be a window. Window sensors monitor the movement of the windows in your home. Glass-Break detectors can also be placed on windows to sense when a window has been broken, indicating an attempt at forced entry.
Door Sensors : These track the opening and closing motion of doors in your home. This is a key part of preventing burglary, as burglars will often need to go through one or more doors, even if their initial entry is through a window.
Key Fobs : These can control the system from a little device on your keys. They are also able to arm and disarm the system and are convenient for when you are outside of your home.

So, as you can tell, there are many ways for you to secure the perimeter of your home and protect your family and valuables. At Cove , we want you to feel as safe as possible. Please take a few minutes to check us out!

Trip Alarm Co 12 Gauge Trip Wire Alarm

Key features:

360° Quad patent-pending design
Rust-resistant stainless steel and aluminum build
Multiple trip lines on a single device
Versatile, reusable, and adaptable design

As an innovative solution to perimeter security, the 12 Gauge Trip Wire Alarm by Trip Alarm Co. offers unmatched detection ability, ensuring peace of mind. Housed in a compact 3 x 1 x 1-inch shell, this lightweight 5-ounce device is expertly crafted from rust-resistant stainless steel and 6061 aluminum. Sporting a 360-degree Quad patent-pending design, it provides comprehensive coverage, alerting users to any breach via a tripwire-initiated system. We like that it gives you the option to set up multiple trip lines on a single device.

It creates a wide-reaching early warning system that’s versatile enough for various settings – from campsites and farms to private properties. Another key highlight is the reusability factor. It can be deployed time and again across different paths and entry zones, secured easily to doors, trees, or gates via screw holes or zip tie notches. We found either to work well.

The American-made device’s sensitive trigger and diverse adaptability make it a reliable choice for property owners and outdoor enthusiasts alike. The use of rust-resistant stainless steel and aluminum grants it durability, potentially surpassing the other options in terms of lifespan. However, unlike the Fith Ops Camp Safe Full 209 Perimeter Trip Alarm Kit, it doesn’t come with a trip wire, and the reflective parts might require camouflage to blend into the environment.

What we liked:

Lightweight and compact
Highly sensitive trigger
Durable and long-lasting
Easy to set up and use

What we didn’t like:

Tripwire not included
Reflective parts may require camouflage

Trip Alarm Co .22 Ramset Micro Perimeter Trip Wire Alarm

Ultra-portable design
Rust-proof construction
Uses .22 Ramset blanks
Loud alarm activation

The .22 Ramset Micro Perimeter Trip Wire Alarm from Trip Alarm Co. delivers reliable and effective perimeter security in a portable, easy-to-carry package. This compact unit measures only 4.25 inches in length and 9/16 inches in circumference. Additionally, it’s exceptionally light at just 1.5 ounces. But despite the small size, it packs a formidable punch in terms of noise output when paired with .22 Ramset blanks, ideal for camping safety or securing private areas.

It’s also quite sturdy and durable, thanks to its high-quality, rust-proof aluminum materials. These are designed to resist wear across multiple uses, ensuring longevity and reliable performance. Speaking of which, it worked without issue when we tested it in various weather conditions. That said, users planning to place it outdoors for extended periods may want to consider weatherproofing the cap’s crimp for added reliability.

One of its defining features is its utilization of readily available .22 Ramset blanks. This avoids the need for potentially expensive and hard-to-find materials. It’s a practical approach that underscores Trip Alarm Co’s commitment to simplicity and convenience without compromising functionality. It should be noted, however, that these blanks aren’t included in the package and must be acquired separately. On the whole, the .22 Ramset Micro Perimeter Trip Wire Alarm offers a well-designed and effective solution for those seeking compact, loud, and durable early warning systems.

Compared to other alarms, its use of .22 Ramset blanks makes it slightly more straightforward in operation. Plus, it sports a significantly lighter weight than the Dahszhi Dual Laser Detector Alarm and a smaller circumference compared to other items on the list. If versatility is what you’re looking for, this one is sure to meet your needs.

For starters, it boasts a compact and lightweight design, measuring 4 x 0.5 x 0.5 inches and weighing just 2.78 ounces. This makes it an ideal companion for backpacking or camping trips. Yet, despite its small stature, there’s a lot of bang for your buck packed into this alarm.

Crafted in the USA with machined aluminum and steel, it gives you the confidence of a sturdy and reliable solution. It shows meticulous consideration for the outdoors with the included 85-foot Dyneema trip line and silicone primer caddy, which can attach to the spool for convenient access. Testing it during a camping trip, we found setup to be straightforward and unproblematic. We secured the trip wire along the unobstructed perimeter of our campsite and mounted the alarm vertically to a tree.

When triggered, it emits a clear and loud 114 dB alarm, which is more than effective in deterring wildlife and trespassers. In an era where security is a must, the Camp Safe Full 209 Perimeter Trip Alarm Kit proves its worth immensely. But as with other similar systems, this kit does not include primers. Still, the fact that this unit is reusable and reloadable makes it a smart buy. Even better, the included 85-foot trip line sets it apart from the Trip Alarm Co. devices that require separate trip wire purchases.

Dahszhi Dual Laser Detector Alarm

Twin infrared beams for reliable detection
Environmental adaptability increases durability
Indoor 300m, Outdoor 60m detection range
Fast response speed 50-700 milliseconds

The Dahszhi Dual Laser Detector Alarm is an exceptionally robust and precise security device. Weighing 835 grams and measuring 6.7 x 3.1, it exhibits a compact yet weighty feel, hinting at its solid construction. Its mounting type is a convenient wall mount, making installation straightforward. Using twin infrared beams, it provides reliable perimeter security. One aspect we appreciate is that it minimizes false alarms caused by falling leaves, birds, or even inclement weather conditions such as rain, snow, or mist.

The alarm also boasts an intelligent automatic adjustment design that adapts transmit power according to environmental conditions. This feature increases the lifespan of the launching tube and reduces power consumption, enhancing durability and energy efficiency. We put the alarm through its paces in both indoor and outdoor scenarios. Indoors, it easily covered a range of 300 meters, while outdoors, it performed well over 60 meters.

But what impressed us most was the speed response, which clocked in between 50 and 700 milliseconds. Combined with its holographic spot real-time report, all of these features contribute to rapid detection and alarm triggering. Despite some initial challenges with instructions that seemed a bit complex due to language translation issues, we successfully installed the alarm after careful review.

Plus, it comes with its own set of installation accessories, so the process wasn’t that big of an issue once the instructions were deciphered. It should be noted, though, that its weight and size are considerably larger than other options, potentially limiting its portability. But its ability to minimize false alarms gives it an edge over the other devices.

High-pitched 91 dB alarm
Portable and lightweight design
Built-in LED flashlight
Suitable for doors and windows

Lewis N. Clark’s Travel Door and Window Alarm stands out as a compact, user-friendly device designed to enhance personal security wherever you go. Its simplistic design belies its effectiveness: when triggered, the unit emits a high-pitched 91 dB alarm, powerful enough to alert neighbors and deter potential intruders. It is tailored for ease of use, fitting seamlessly into the doorframe gap, with a cord looped around the door handle to ensure firm placement.

This feature also extends to windows, thereby amplifying its utility. Designed for portability, this petite and feather-light device – measuring only 7.05 x 3.19 x 1.14 inches and weighing a mere 3.2 ounces – makes it an essential companion for travelers. It can snugly fit into a suitcase, backpack, or even a handbag, making it readily accessible.

An additional built-in LED flashlight feature adds an extra layer of convenience, especially in unfamiliar or poorly lit environments. During testing, the setup process proved effortless, so it’s a breeze to use, even for novices. Its ear-piercing alarm promptly activated upon breach, demonstrating the alarm’s reliability. Moreover, the LED flashlight provided ample illumination in dark surroundings, further reinforcing its worth as a travel-friendly safety tool.

Comparatively, its suitability for doors and windows potentially offers more versatility than some other alarms. The built-in LED flashlight is also a unique feature not seen in the other solutions we reviewed. However, it falls short in terms of sound level compared to the Fith Ops alarm. But its simple setup procedure, like the .22 Ramset Micro Perimeter Trip Wire Alarm, can make it an easy choice for those looking for hassle-free operation.
