20AXIS 223M - Video and Image Settings
Camera Settings
To compensate for poor lighting conditions, you can adjust the Color level, Brightness, Sharpness, Contrast, and the Exposure control.
The settings for low light behavior determine how the camera behaves at low light levels. These settings affect video image quality and are basically a measure of how much noise to allow in the video images.
Please see the online help 
for further information on these settings.
