I got one of these too. I already sent it back and am waiting for a replacement. My trouble was that it would not receive a signal from my Hawkeye II or from the Eagle Eye if the motion sensor was mounted anywhere outside of the room the Commander was in. Anyone else have this trouble. I am trying to monitor a front door and send the signal into the house about 25' away in a bedroom. It never would activate unless I took the motion sensor into the room with it.
