Looking for a security alarm that will trigger if someone walks past it (laser trip switch)?
My car was broken into and the GPS stolen the other week while sitting in my home's driveway. I'd like to buy some alarms that would signal me if anyone walks through an invisible laser path though I don't know a good system to pick up. I already have Brinks security and the conventional door / window alarms. So, having this laser "trip trigger" would allow me to shine it in the backyard (which has access to a back alley) and notify me if anyone walks through it in the night.
Any ideas where to pick some up or good systems to buy?
Go to a well stocked Hardware store (Home Depot, etc.) and get a 'motion detector' light and point it to the area you want coverage for.
Instead of screwing in a light bulb into the sockets, put a socket-to-plug adapter so you can plug an extension cord in and run this back to the house.
There, take the cord and plug it in to any kind of 110Vac device that will sound a bell, or buzzer, or chime, etc. when it has electricity sent to it.
If you have critters (raccoons, rabbits, cats, dogs etc.) in the neighborhood, you'll need to have the sensor field narrowed down and focused for man sized targets.
Now, when a body passes into the detection field, the motion detector will 'open' a circuit back to your 'alarm' and you can get your 12ga. and 'investigate'.
I use this method for deer hunting from the front porch.
