Automatic Gain Control Settings
Automatic Gain Control (AGC) allows for the amplification of the video signal in scenes
with minimal ambient light. Many low-light scenes result in picture noise. As gain is
increased, the picture noise is also amplified.
When AGC is enabled, the gain setting value is based on feedback from the camera. When
AGC is disabled, the camera uses the manual gain setting value. The trade-off between
picture level and noise may be adjusted when AGC is disabled.
