DIY Perimeter Alarm To Protect Your Home & Camp

Protecting your home and camping site from intruders and unwanted visitors can be difficult, but with a DIY perimeter alarm, you can easily help deter potential burglars and keep your family and valuables safe. Here’s how you can build your own DIY perimeter alarm to guard your home or campsite.

Step 1: Gather Your Materials

To build a simple DIY perimeter alarm, you will need a few basic materials. These include an old cellphone or tablet (with enough memory to store an application), some wires, a few sound/light sensors, some magnets, a few relays, a 9V battery, and a few other Electronics components.

Step 2: Setup the Sensors

Once you have all of your materials, the first step in creating your perimeter alarm is to setup the sensors. Attach the sound/light sensors to the outside perimeter of your home or camp. Make sure to place at least one sensor on each side of the home or camp, and also make sure the sensors are close to the ground to ensure they are activated by any movements or sounds.

Step 3: Connect the Wires and Magnets

The next step is to connect the wires and magnets to the sensors. Have the wires run from the sensors to the relays, and then connect the relays to a 9V battery. When the sensors detect a movement or sound, it will send a signal to the relays and the magnets will be activated.

Step 4: Attach the Phone or Tablet

The last step is to attach the phone or tablet to the relay. This will allow it to be connected to the internet and receive notifications whenever the alarm is activated. Once the phone or tablet is connected, download and install an alarm application. This will allow you to customize the alarm to your various needs.

Step 5: Test the Alarm

Once the alarm is setup, it’s important to test it out and make sure everything is working properly. Running through a few false alarms and then activating the real alarm will give you a good indication of how well it works. After everything is running correctly, you can then start using your DIY perimeter alarm to keep your home or camp safe.


Installing a DIY perimeter alarm is an easy and cost-effective way to help protect your home or camp from intruders. With the right materials, a little bit of time, and some patience, you can create a reliable and powerful alarm that will keep you and your family safe from potential harm.
