Installation
The installation of CCTV (closed-circuit television) involves the video signal being carried by coaxial cable and this is from the camera to the monitor. The installation process should be in compliance with relevant regulations such as the Institute of Electrical Engineers latest edition. The arrangement or the installation should allow flexibility in the design of complicated systems, such that when more than one camera is required, a video switcher must be included. With the use of a switcher, any camera may be selected to be held on the screen or it can be set to sequence in turn through all the cameras.
