Improvised Perimeter Alarms
In the woods, you can rig up some fishing line to your cooking gear or cans and fashion a trip wire alarm. For home security this doesn’t translate well, who really wants fishing line running around their yard and pots and pans in their yard?
A simple solution for this can be using driveway alarms as improvised perimeter alarms or an electronic tripwire!
If you aren’t familiar with driveway alarms, they consist of a tiny box that causes a remote chime to sound when something breaks it’s beam.
Benefits to these driveway alarms:
- Works up to 200 feet away
- Wireless installation
- Weather resistant
- Receiver chimes when sensor is crossed
One caveat to remember, if you want to cover multiple approaches, verify you can change channels on the sensors and the alerts they trigger. If not then try to get units from different vendors. Otherwise you’ll end up with a single sound for all your regions, triggering all chimes (same frequencies) and will leave you unsure if the alert originated from the front of your property, the sides or or to the rear of your property. This can be mitigated if the units have multiple frequencies and multiple alert chimes.
In direct sunlight these can be unpredictable. Also make sure to put them high enough that dogs, cats or woodland creatures don’t set them off and avoid aiming these units towards vegetation that can be moved by wind.
