What is the maximum distance I can send the camera's signal?
The maximum range of X10 wireless cameras is 100 feet. The range of your camera depends on environment--wireless interference, wall and home exterior materials, the number of floors the signal is traveling through, etc.--and where you use the camera.
The cameras transmit through walls and ceilings, but you might need to experiment with the orientation of the flat antennas on the camera and Video Receiver. Try to position them so they face each other. This will boost reception range.
