Interesting. Several weeks ago I was looking inot various intrusion systems, and this was one of them I saved. Query: Remember the sensors picture from Freedom Ridge? My best guess after some study was it's either thermal, Infrared, or a break-beam. though that would seriously limit the range between recievers.. Will try to see y'all Tuesday R*
