Whether you want to secure the perimeter of your home, your bug out location or a camp site, this DIY tripwire alarm (if placed correctly) will surely disclose any stealthy intruder.
When setting up home defenses you should always keep in mind a few military principles. For example OCOKA is a military procedure used for setting up perimeter defenses and stands for:
- Observation and fields of fire
- Cover and Concealment
- Key Terrain
- Avenues of Approach
When choosing the place for the alarm you have to take into consideration all 5 principles of OCOKA.
Because one man cannot guard 24/7 a 360 degree perimeter, a tripwire alarm can be your invisible comrade guarding your back.
And it’s all very simple because all you need is a personal key-chain alarm ($4.5 – but probably you can find it even cheaper) and a fishing wire. And 10 minutes max. This is one of the things that I’ve learned from a well-known army officer vet Steve Walker, for whom I have all the respect in the world.
