Review on White SecurityMan SM80 Wireless PIR Motion Sensor for Air-Alarm Systems by Vedavyas Fleming

I bought 4 of these motion sensors and only 2 of them work. Together. promises replacement when writing, but we'll see. There were a lot of calls to tech support but no one answered the call but when I got through to them I had some technology that I had a hard time understanding. I will rate this review again later. Update: They responded after going through all the RMA mailings and phone calls. I finally got my new detectors so I have to give them 2 extra stars. I got one of these up and running and it seems to be working fine. will wait a while before activating another one to make sure it doesn't trigger false alarms.
