22AXIS 233D - Video & Image Settings
Low Light Behavior
The settings for Low Light Behavior determine how the camera behaves at low light levels. These settings affect video image quality and frame rate.
•Exposure control - This setting is used to adapt to the amount or type of light used. Automatic is the default setting and can be used in most situations. The shutter speed is automatically set to produce optimum image quality. Use Manual if you have special requirements for the exposure setting. Allow slow shutter can be enabled/disabled when the exposure control is set to Automatic.
•Max exposure time - Increasing the exposure time will improve image quality, but at the expense of the frame rate. There may also be an increase in motion blur.
•Max gain - Measured in decibels (dB). A high level of amplification may provide
a better image in very low light situations. Please use the online help files for more information.
