Backlight Compensation
(not available when Auto Exposure Mode is set to

bright light source is behind the subject of interest, without backlight compensation, the subject would
appear in silhouette. The camera can adjust the exposure of the entire image to properly expose the
subject in the foreground. Select one of the following options:
OFF
(default)
, Upper, Lower, Central
1/3rd, Central 1/6th, Left,
or
Right

Gain
(only available when Auto Exposure Mode is set to
Manual
): Increasing the gain lightens dark
pictures resulting from low-level lighting. Move the slider or manually specify a value between
0-48
, in
dB. The default is
0
.
Digital WDR
: Improves the image quality and amount of details in high contrast scenes. Such scenes
combine areas with different lighting conditions; some areas are very bright, and others are dark.
Without Digital WDR, the image either would be overexposed or too bright in bright areas and
completely dark in dark areas. Digital WDR helps improve image quality by producing a more detail in
both the dark and bright areas of the image.
Select
High
,
Medium
(default),
Low
, or
OFF
. When High is selected, the image has the highest wide
dynamic range, so that the IP camera can capture the greatest scale of brightness. Selecting OFF
disables this function.
White Balance Mode
: Adjust to create the best color rendition.
•
ATW
(Auto Tracing White Balance; default): Color is continuously adjusted according to the color
temperature of the scene illumination.
•
Auto
: Color in a scene is automatically adjusted according to the ambient lighting between 2500°K to
10000°K.
