Set Up AGC Exposure Mode to Maintain Constant Framerate

Floating Framerate

For low-light applications, the camera increases exposure time in automatic exposure mode to maintain image quality.

You can switch to AGC exposure mode to keep the framerate constant.

AGC Mode

Auto gain control, manual exposure time.

When AGC mode is enabled, gain is set automatically. The initial exposure value adjusts based on the current streaming framerate to maintain a constant framerate.

AGC Mode


Limit Exposure Range in Auto Exposure Mode

(Default Exposure Range) When switching to Auto Exposure Mode, the Exposure Time Range is automatically set to the default range based on the selected streaming format.

You can limit the exposure range even in Auto Exposure Mode. This is useful when you want to avoid overexposure or motion blur in specific lighting conditions. The default exposure range varies depending on the selected resolution and framerate.

The current Exposure Time and Exposure Gain values are displayed after the camera starts streaming and are updated every second to reflect real-time changes.
