AES (Auto Electronic Shutter) or AGC (Auto Gain Control) – Security Camera Switches & Adjustments


AES (Auto Electronic Shutter) or AGC (Auto Gain Control)

The AES or AGC is an automatic light-adjustment that can reduce glare and is used mostly on cameras that do not use auto-iris lenses. It is normally set to ON and automatically adjusts picture gain in accordance with the brightness of the subject. When it is set to OFF, some cameras will not automatically switch from color to monochrome when the light fades.

    Good to know! Will it do anything with an auto-iris lens, or is it only beneficial with a manual-iris lens?

    Is this feature significantly different from the BLC which is right below the AES switch? What would the difference be?
