Hello all,
We've had a disturbing number of car break-ins in our neighborhood lately, which got me thinking about using my Elk security system, or ISY to monitor them.
One thing that came to mind was to use one or more PIR motion sensors aimed at the area, but the beam pattern is much to wide and would probably trigger a lot of false alarms. I suspect it would be possible to narrow the pattern by masking or refocusing the beam, but I haven't explored that area yet. I've also seen devices that create an RF field around the car, but those are intended to be used with the vehicle alarm. I suppose one could use a light beam to surround the area, but that would require a couple of very solid posts for the turning mirrors (and a way to shield them from the great outdoors).
Any other thoughts? I'll be retiring soon and need another project to add to the list.
Tom
