The instructions say to mount the motion sensor at 4 to 5 feet high, but the video showed a guy mounting one in a staircase just above his head at over 6 feet high. In test mode, the motion sensor mounted at 4 feet high could not detect me crawling by it about 12 feet away in a 10x12 or so room with adjoining hall.
Do you think I have it too low? The ceiling in the room is 8 feet high and 4 feet seems low and looks funny.
