Auto Gain Control
(AGC)
This AGC function provides clear image in low light condition.
This controls an amplifier that is used to boost the video signal
when the light dims so as to increase the camera’s sensitivity.
In some bright environment, the amplifier may be overloaded
and which may distort the video signal. So, it is necessary to
monitor the signal level with AGC control circuit and AGC has to
be switched off in case of necessity.
