In our previous post we discussed Network Cameras for Home Security, but what if it’s dark, or you’re asleep and someone is creeping up to your house?
If I was camping in the woods, I’d rig up some fishing line and my cooking gear into 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 and economic answer an electronic tripwire, A driveway alarm.
If you aren’t familiar with a driveway alarm, it’s 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
- Wireless infrared alert system
- Weather resistant design
- Receiver chimes when sensor is crossed
One caveat to remember, if you want to use multiples, 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 are 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.
For an economic electronic tripwire, find yourself some driveway alarms, but make sure to read the reviews from other buyers to ensure that it will provide the quality you need and serve your purposes!
