The image data is usually transmitted over a coaxial cable. The signal transmitted over these cables is then fed into a monitor or set of monitors if the image needs to be visible indifferent locations. • Wireless CCTV System: Basically, Wireless CCTV systems are similar to wired CCTV systems. The difference is that a radio transmitter is attached to the camera. A radio receiver then attached to the input on the monitor system or computer.
