Protecting your home and camp is more important now than ever. Setting up a perimeter alarm is an easy and inexpensive way to do just that. Here’s how to make your own DIY perimeter alarm quickly and easily.

Step 1: Materials Needed

The materials you need to make your DIY perimeter security alarm are relatively inexpensive and easy to obtain. You’ll need:

  • An array of PIR (passive infrared) motion detectors
  • A control box
  • An external warning device (alarm siren, spotlights, flashing LED light, etc.)
  • Power source (battery or AC power)
  • Mounting materials and wiring

Step 2: Placement of Motion Detectors

The key to a good perimeter alarm system is proper placement of the sensors. When placing motion detectors, be sure to place them in areas that are highly visible and will trigger an alarm if someone enters the property. For example, you can place them around the perimeters of your home and camp at doorways, windows, paths, and other vulnerable entry points. It’s also a good idea to place sensors at least 3 feet away from any structures, as this will reduce false alarms.

Step 3: Connect Motion Detectors to Control Box

Once you have placed the motion detectors in the optimal positions, you can begin wiring them to the control box. The control box is the central unit that receives signals from the sensors and triggers the alarm if a breach is detected. Make sure all the wiring is secure and tightly connected to the control box, then set up the power source.

Step 4: Connect External Alarm and Test System

Now it’s time to connect the external alarm and test the system. A typical system will include a siren, spotlights, and a flashing LED light. Connect the alarm and any other external devices to the control box and test that they are working properly. Once all the components are connected and functioning properly, your DIY perimeter alarm is ready for use.


Creating your own DIY perimeter alarm is an easy and affordable way to protect your home and camp. With the right materials and a bit of effort, you can set up an effective security system that can give you peace of mind in your space.
