Why Should You Consider a Perimeter Alarm System?

Imagine this: You’re out of the city and on your way to meet some friends at your cabin in the woods–a place where you’ve always felt safe and secure. But, when you arrive, you notice that something is amiss. Your front door is wide open, and there are signs of suspicious activity everywhere. It’s clear that someone has broken into your home.

Scary, right? If you’re like most people, the very thought of your home being invaded is enough to send shivers down your spine. And, if you’re preparing for a survival situation or other emergency, this kind of incident can be especially dangerous and unsettling. But, by investing in a perimeter alarm system, you can help protect yourself and your family from these kinds of threats.

A perimeter alarm system is a device or set of devices designed to detect intruders attempting to gain access to your home or property. These systems typically include motion detectors, which will trigger an alarm when they sense the presence of a person. The alarm can either be audible, such as a siren or bell, or visual, such as flashing lights.

High Tech vs Low Tech Alarm Systems

When it comes to protecting your home against intruders, you have two main choices – high tech perimeter alarm systems and low tech DIY options. Both offer their own benefits and drawbacks, so how do you decide which one is right for your home?

To start with, high tech security solutions are typically more expensive than low tech options. They typically require professional installation and maintenance, while low tech systems can be easily installed by anyone. However, high tech systems often offer more features than their lower-tech counterparts. They are also generally less likely to malfunction or break down, because they use technology designed to withstand many different types of impacts.

On the other hand, low tech systems are generally less expensive and easier to install. They can also be built with materials you already have at home, such as scrap wood or leftover wires from other projects. Additionally, low tech systems often include features like tripwires and alarms that let you know when someone has broken in or is trying to get into your home.

How Trip Wire Alarms Work

Tripwire alarms provide a low-tech security system that is easy to set up and maintain. These alarm systems consist of a wire strung between two posts, trees, or stakes on the ground in your yard. When an intruder trips over this wire, it triggers one or more alarms to alert you that someone has entered your property. The alarms can range from simple bells and sirens to strobe lights or even barking dogs.

There are several different types of trip wire alarms, but they all work in the same basic way. The alarm system consists of two components: the trip wire itself and the alarm unit that detects when the wire has been tripped. The most common type of trip wire is made from galvanized steel wire, although you can also use a monofilament fishing line. The cable is generally installed at a height of about 2 to 3 feet above the ground, although this can be adjusted depending on your property and the security needs.

The alarm typically consists of a metal contact connected to a battery-powered siren, strobe light, or dog barking unit. When an intruder trips over the tripwire, the contact on the alarm is broken, triggering the alarm. Some alarms also have motion detectors that can detect when someone has entered your yard and trigger the alarm even without tripping over the wire.

One of the main benefits of a trip wire alarm is its low cost. You can easily set up an effective system for just a few dollars, making it a great choice for homeowners on a budget or those needing to protect their property while they are away. Another advantage of these systems is the ease of installation and maintenance. You simply have to run the wire between the two posts, trees, or stakes and connect it to the alarm. This makes it easy to install these systems in just a few minutes without needing any special tools or skills.

5 Different Kinds of Perimeter Alarms to Consider

Activating a home alarm system

As preppers and survivalists, it is vital to be prepared for any type of situation that might arise. One area in which many people do not pay enough attention to is securing the perimeter of their homes or properties. An effective perimeter alarm system can help give you peace of mind and protect your belongings from intruders and other unwanted visitors.

There are a variety of different types of perimeter alarms that you can consider using, depending on your needs and budget.

1. Motion-Activated Outdoor Lights

One popular option is the motion-activated outdoor lights, which make it easy to spot anyone approaching your property. It works by using a motion sensor to detect when someone is nearby, and then turning on the lights to illuminate their path. This type of alarm system is relatively inexpensive and easy to set up. It is an excellent option for homeowners who do not want to invest too much time or money into their security measures.

2. Wireless Sensors

Another option is to use wireless sensors that can be easily installed along the perimeter of your property, alerting you whenever there is movement in the area. These sensors are usually small and unobtrusive, making them an ideal choice for those who do not want to disrupt the look of their property.

3. Smart Home Technology

For those who want a more high-tech approach, smart home technology can provide sophisticated perimeter alarms connected to your smartphone or other devices. These systems can automatically turn on your lights when you are away, or alert you whenever there is unusual activity near your property.

4. DIY Alarm Systems

If you are looking for a do-it-yourself solution, many pre-made DIY alarm systems can be easily installed along the perimeter of your yard or property. They include motion sensors, alarms, and even security cameras, giving you a complete system for monitoring your property.

5. Security Cameras

Finally, security cameras are another great option for adding an extra layer of protection to your perimeter alarm system. They can help you keep an eye on any activity near your property, and also act as a deterrent against would-be intruders.

So whether you are looking for a simple, low tech solution or a more sophisticated option, there are many different types of perimeter alarms to choose from. By carefully considering your needs and budget, you can find the perfect system for protecting your property and keeping you and your family safe.

Top Five Low-Tech Perimeter Alarm Systems You Can Build Yourself

As preppers and survivalists, we all know how important it is to have secure perimeter alarms systems in place in case of an emergency or disaster. But what do you do if you don’t have the necessary equipment or technical knowledge to build a high-tech system? Luckily, there are several low-tech options that you can easily create at home with just a few common materials.

Here are my top five picks for do-it-yourself perimeter alarm systems that are easy to build and require minimal materials and technical knowledge:

1. Tripwires and alarms.

This is a classic perimeter alarm system that has been around for centuries. All you need are some simple materials, such as fishing line or string, metal cans, paper cups, or any other objects that can be easily moved by someone passing through the area.

How To Make:

  • Simply tie one end of the string or line to a post or tree, and run it along the perimeter of your property.
  • Attach the alarm device at various intervals so they will be tripped when someone crosses through.
  • Place the alarm device on the string or line and attach it using a clothespin or other small object.
  • You can use empty cans, cups, or anything else that makes noise when moved by the wind or tossed around.

2. Motion-activated lights.

For those with a little more technical knowledge, this is one of the best low-tech noise and light perimeter alarms you can create at home.

How To Make:

  • Start by placing a motion-activated light or flood light near the perimeter of your property.
  • Then, use a length of wire to run to an electronic buzzer or siren that will sound when the light is activated.
  • You can do this by attaching the line to one pole, and placing the buzzer or siren on another. Alternatively, you can use a motion-activated switch to trigger the alarm.

3. Cans and bottles filled with gravel or pebbles.

This simple perimeter alarm system is easy to create and highly effective, making it the perfect choice for those on a tight budget or who do not have access to high-tech materials.

How To Make:

  • Fill an empty soda can or other metal container with pebbles or gravel, and then tie it to a rope or string placed along your property’s perimeter.
  • When an intruder trips the rope or crosses through the area, the can will come crashing down, creating a loud noise that will alert you to their presence.

4. Pressure-sensitive door mats and doormats

This simple do-it-yourself alarm system is a great choice if you want to add an extra layer of security at your front or back door.

How To Make:

  • Place a pressure-sensitive doormat or floor mat in front of your door, and run any type of wire along the perimeter of your property to the doormat. Connect this wire with a buzzer or other alarm device, and you’ll get an alert any time someone steps on the doormat.
  • When someone steps on the doormat, it will send a signal to your wired alarm system, triggering a loud siren or warning alert.

5. Simple alarms with bells or whistles

If you do not have access to electronic buzzers and sirens, this simple do-it-yourself alarm system is the perfect choice. All you need are a few small bells, whistles, or similar objects that can be easily triggered when someone crosses through your property.

How To Make:

Just tie the bells or whistles to a string and run it along the perimeter of your property. When someone passes through, they will be met with a loud ringing or whistling sound, letting you know they are there.

With these simple do-it-yourself perimeter alarm systems, you can easily add an extra layer of security to your home and protect yourself and your family from intruders.

What Other Options to Protect Your Perimeter are Available?

There are many options available when it comes to protecting your home or property from unwanted intruders.

Camera System

One of the most popular and effective do-it-yourself perimeter alarm systems is a camera system. Cameras allow you to monitor your property from anywhere in the world, giving you peace of mind and quickly identifying any potential threats.

Get Dogs

Another option for protecting your perimeter is with the help of dogs. A well-trained guard dog can be an effective deterrent to would-be intruders, and can even warn you of an intruder’s presence before they can do any damage.

Motion Detectors

Lastly, motion detectors are another popular choice for perimeter protection. These devices are typically small and unobtrusive, yet can be extremely sensitive to movement, helping alert you to potential threats right away.

How To Conceal Your Alarm System?

When it comes to protecting your home from intruders, nothing can be more effective than a do-it-yourself perimeter alarm system. This type of alarm system is easy to set up and highly customizable, allowing you to choose the layout and placement that best suit your property. But one of the biggest challenges when setting up a DIY perimeter alarm system is concealing the alarm sensors so that they do not draw attention to your property.

Fortunately, there are a number of simple and low-tech solutions for this problem.

Option#1 – Use plants or other natural materials to disguise the alarms, either by surrounding them with tall vegetation or by placing them in pots of camouflaged colors. This is a quick and easy way to conceal your alarm sensors without compromising their effectiveness.

Option#2: If you want your alarm system to be less visible, try painting or staining the sensors in colors that blend in with the surroundings, such as browns and greens for outdoor use or dark neutrals for indoor use.

Option#3: Another option for concealing your alarm sensors is to hide them in inconspicuous places, such as behind door knobs or underneath furniture. You can even choose to conceal the majority of your alarms and use a few strategically placed sensors as a decoy to fool potential intruders.

Ultimately, the best way to keep your perimeter alarm system concealed is to plan and experiment in advance. By taking the time to evaluate your property and think through potential placement options, you can create an alarm system that both provides protection and blends seamlessly into its surroundings.


As more and more preppers and survivalists are looking for ways to keep themselves and their families safe, do-it-yourself perimeter alarm systems have become an increasingly popular option.

These simple and low-tech systems can be easily set up in your home or property, alerting you when someone enters your space without permission. Whether you’re trying to protect yourself from intruders in a post-disaster world or just keep your property secure, do-it-yourself perimeter alarm systems are an effective and affordable solution.

So, if you’re looking for a simple but effective way to stay safe, consider investing in one of these easy and low-tech DIY alarm systems today!
