Working with AGC and Open Shutter Settings

The SpeedDome Ultra 8 camera dome provides settings for compensating for low-light scenes
in color: Automatic Gain Control and Open Shutter. Automatic Gain Control (AGC) amplifies
the video signal in scenes with minimal light. Many low-light scenes result in picture noise. As
gain is increased, the picture noise is also amplified.
