Monitors

CCTV monitors are used to view the pictures from CCTV cameras, converting the electrical signal into an optical image to be presented to the system operator.

They’re similar to domestic televisions but differ in two respects. Firstly, a monitor has no radio frequency decoding circuitry. Its signal input is ‘base-band’ video as opposed to the aerial input of a television. Secondly, CCTV monitor tubes have a higher resolution than a domestic television. A good quality monochrome CCTV monitor will have a resolution in excess of 800 lines at the centre of the tube; a television is unlikely to exceed 400 lines.

Monitors are defined by their tube size, which, like televisions is their approximate diagonal dimension. Common monitor sizes:

When working out which size monitor to use, it is generally regarded that the optimum size for a particular application is between 1/3 and 1/5 of the distance from the screen to the operators position.

Later models use TFT LCD displays. These have a number of advantages over conventional CRT monitors:
