Working with AGC and Open Shutter Settings

The SpeedDome Ultra VII 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.

When AGC is enabled, the camera automatically adjusts the gain setting value. When AGC is disabled, no gain is applied to the video signal. This may make the video appear darker on the monitor.

The gain setting for the camera differs from the maximum gain (Max Gain) setting available on the Camera Functions menu. The Max Gain setting is an upper limit for how much gain can be increased when AGC is enabled. The trade-off between picture level (brightness) and noise may be adjusted by setting the Max Gain value. Lower values for Max Gain setting may result in a darker picture with less noise. Higher values for Max Gain setting may result in a brighter picture with more noise.

In addition to the AGC settings, you may also adjust the Open Shutter settings to improve dome performance in low light conditions. For more information, continue with Understanding How Advanced Shutter Settings Improve Low-Light Performance.
