between light and dark in an image. Test the different levels to find the one that
works best of your light conditions.
• Backlight compensation - this setting is used to make the subject appear clearer,
e.g. against a bright background.
Low Light Behavior
The settings for Low Light Behavior determine how the camera will behave 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
Max exposure time - Increasing the exposure time will improve image quality, but at the
expense of the total frame rate. There may also be an increase in motion blur.
Max gain - Measured in decibels (dB), the default value is 36 dB. A high level of
amplification may provide a better image in very low light situations.
Shutter speed - A slower shutter speed in dark conditions will help to produce a brighter
image, but will produce fewer frames per second which may cause images to be blurry
during motion.
Please use the online help files for more information.
Image Settings
• Auto focus enabled (default setting).
• Stabilizer - When monitoring an environment that is subject to vibrations (i.e.
traffic control) the images can appear to be unsteady. Choose the frequency (High
or Low) that best applies to your environment to improve image quality.
• Image freeze on PTZ - Set this option to On to freeze the image during camera
movement. Once the camera reaches its position the current image is shown. Auto
freezes images only between preset positions.
