Wireless security cameras function best when there is a clear line of sight between the camera and the receiver. Outdoors, and with clear line of sight, digital wireless cameras typically have a range between 200 and 400 feet. Indoors, the range can be limited to 150 to 180 feet. Cubical walls, windows, glass, and drywall generally do not displace wireless signal strength. Brick, walls, and concrete floors degrade signal strength. Trees that are in the line of sight of the wireless camera and receiver may also influence signal strength
