Keeping your home and campsite safe from intruders is possible when you construct your own DIY (Do It Yourself) perimeter alarm.
Step 1: Gather Materials
- Wire mesh
- Dustbin detector (aka PIR)
- Soldering iron
- Insulating tape
- Alarming device (e.g. ringing alarm)
Step 2: Building The Alarm
Take the wire mesh and use insulating tape to strengthen the edges and make sure no gaps remain.
Now carefully solder the dustbin detector (PIR) to the wire mesh. Make sure that the PIR is accurately connected, since any flaws can lead to false alarms.
The PIR or dustbin detector should now be securely attached to the wire mesh.
The last step is to attach the alarming device to the PIR. The alarming device must be set off when motion is detected. This can be done with a simple ringing alarm, or something more elaborate.
Step 3: Setting Up The Alarm
The perimeter alarm is now ready for use—now you can begin to install it and set it up. Start by finding a suitable spot to place the alarm.
You should place the alarm along the perimeter of your home or campsite—ideally, it should cover all main entry points. Make sure it is as far away as possible from any trees or bushes that may set it off accidentally.
The last step is to set the alarm. Adjust the sensitivity settings of the PIR so that the alarm will sound when it detects motion. Test the alarm before you go to bed and make sure it is working correctly.
Conclusion
Constructing your own DIY perimeter alarm is a great way to protect your home and campsite from intruders. You can do it yourself and it is inexpensive and easy to set up. Just be sure to test the alarm thoroughly before you leave your property.
