How CCTV works?

Cabling of the CCTV
A CCTV camera uses some cables to transmit data from the camera to the laptop or desktop. The wires of the CCTV camera should be on the protective pipe, of plastic or metal, to prevent it from destruction from mice and other rodents. Any disruption of these cables will inhibit the transmitting of information from the cameras. The cable is the most active part of the camera. Some of the cameras do not use cable; they transmit the data through internet protocol. Digital CCTV cameras store their footages on the web browser, and the only challenge it faces is when there is no internet, the CCTV camera will fail to move the data to the video recorder.
