Gamma Correction-What is it and how does it effect Security Camera Systems

Question

Gamma Correction(what is it and how does it effect CCTV?)

Answer
Gamma correction is a typical camera specification.

It is an electronic correction carried out by the camera circuitry to balance the brightness seen by the camera to that of the monitor.

The typical setting available is .045.

It is usually a selectable On/Off feature for most cameras.

Basically it sometimes has to be used especially with older CRT monitors where it is trying to balance the signal due to brightness.
