Function:
Turn on/off the backlight compensation feature.
A sharp contrast of brightness and darkness may arise when a bright
backlight is present. This usually leads to a vague dark or even
silhouetted image of a subject under surveillance. Under such
circumstances, the backlight compensation can be used to achieve a
suitable exposure level so as to get a clear view of the subject.
With backlight compensation, the camera becomes more sensitive
to the light level in the center of the picture, and thus, enhances the
image quality of the subjects in this area.
Options: ON -
Enable the backlight compensation.
OFF -
Turn off the backlight compensation (default).
