DIY Perimeter Alarm To Protect Your Home&Camp

If you’re looking for an easy way to secure your home or camp, consider building a DIY perimeter alarm system. When it comes to technology-based home security, many people feel they are out of their depth. But the truth is, you don’t need to be an experienced techie to build a perimeter alarm that will effectively protect your home or camp. Here are the steps you need to follow for constructing your own DIY perimeter alarm system.

Materials Needed:

  • Magnetic reed switches
  • Wire
  • Battery
  • Siren
  • Motion sensor

Step One: Setup the Magnetic Reed Switch

The first step is to set up the magnetic reed switches. These are small electrical switches that are triggered by a magnet. You will need to connect the switches to each entry point of your home or camp. You can set them up on doors and windows.

Step Two: Connect the Alarm System Wiring

Once the switches are in place, you need to connect the wiring to the alarm system. Connect the wire from the switch to a battery. Then, connect the battery to the siren and the motion sensor. The motion sensor is optional but it adds extra security as it will detect any intruders before they can get close to the home or camp.

Step Three: Test Your Alarm System

Once the system is wired up, the last step is to test it. To do this, open one of the doors or windows and make sure that the siren is triggered. If the siren does not sound, you may need to check that the wiring connections are secure. If that doesn’t fix it, you may need to replace the batteries.


Creating your own perimeter alarm system is a great way to protect your home or camp without breaking the bank. Once you’ve completed these steps, your system should be up and running. Always test it regularly to make sure it functions properly.
