Please see the online help for further information on these settings.

Low Light Behavior

Low light conditions can reduce image quality and increase bandwidth usage. The Low Light Behavior settings define the balance between image quality and frame rate. During low light conditions, experiment with the settings Exposure priority, Max exposure time and Max gain until you achieve an acceptable image quality at the required frame rate.

Exposure priority defines the balance between image quality and the frame rate. Higher image quality may reduce frame rate and increase motion blur. A prioritized frame rate may instead increase image noise.

By increasing the Max exposure time the quality of the image will increase, but the frame rate will decrease. There may also be an increase of motion blur.
