DIY Perimeter Alarm To Protect Your Home & Camp

Protecting your home and other areas from intruders can be challenging and expensive, but with some DIY ingenuity, you can create a perimeter alarm that will help keep your property safe. Here’s how to make a simple, yet effective alarm system that will alert you if someone tries to enter your site.

Step 1: Collecting Materials

For this project, you will need several materials. Begin by gathering the following items:

  • Two motion sensor lights
  • Two durable plastic tripwires
  • Two stakes
  • Tomahawk tie wire
  • A 12-volt battery
  • Two electrical extension cords
  • Two electrical outlets

Step 2: Setting up the Lights

Using the electrical cords, plug the motion sensor lights into the outlets and position them around the perimeter of the area you’d like to protect. Set the timer and make sure to check the lights regularly to ensure that they’re functioning properly.

Step 3: Installing the Tripwires

Install the tripwires at each end of the lights’ range. Stretch one wire tightly between the two stakes and make sure it’s taut. Secure the wire to each stake with the tomahawk tie wire. Repeat this step for the other tripwire.

Step 4: Connecting the Tripwires and the Lights

Attach one end of the 12-volt battery to the terminal on one of the motion sensor lights. Connect the other end of the wire to one of the tripwires. Repeat this step for the other light and tripwire. When an intruder trips the wire, the connected light will turn on, breaking the circuit, alerting you.


Your DIY perimeter alarm system is now complete and ready to protect your property from intruders. This system is easy to set up, affordable, and can be modified to suit your needs. Keep your home and camp safe with this simple and effective alarm system.
