Whether you want to protect your home’s perimeter, your bug-out spot, or a campsite, this DIY tripwire alarm (if properly placed) will certainly expose any stealthy intruder.
You should always keep in mind a few military principles when setting up home defenses. OCOKA, for example, is a military procedure used to establish perimeter defenses, and stands for:
- Observation and fields of fire
- Cover and Concealment
- Obstacles
- Key Terrain
- Avenues of Approach
When choosing the alarm location, all 5 OCOKA principles must be taken into account.
Since one man can’t keep a perimeter of 360 degrees 24/7, 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 you might find it even cheaper) and a fishing wire. And, max. 10 minutes. This is one of the things I’ve learned from a well-known military officer vet Steve Walker, for whom I have all the worldwide admiration.
