Exposure Value
This is a number that represents a combination of a camera's shutter speed
and f-number, which brightens or darkens the scene accordingly. Select from the following
options:
-2, -5/3, -4/3, -1, -2/3, -1/3, 0, 1/3, 2/3, 1, 4/3, 5/3,
or

. The higher the number, the
brighter the image. The default setting is
0
.
Backlight Compensation
In images where a bright light source is behind the subject of interest,
the subject would normally appear in silhouette. The backlight function of the camera allows it to
adjust the exposure of the entire image to properly expose the subject in the foreground. From
the drop-down list, select one of the following options for the backlight compensation:
OFF,
Upper 2/3rd, Lower 2/3rd, Central 1/3
rd
, Central 1/6
th
, Left, Right,
or
OFF
(default setting).
The settings are as follows:
Highlight Compensation
This setting masks bright light sources that are directed at the
camera. Select
ON
or
OFF
(default setting).
Digital WDR
This function improves the image quality and amount of details in high contrast
scenes. Such scenes combine areas with different lighting conditions, where some areas are
very bright and others are dark. If this function was not used, the image either would be
overexposed or too bright in bright areas and completely dark in dark areas. Digital WDR helps
to improve image quality by producing a larger amount of details in both the dark and bright
areas of the image.
Select
High, Medium, 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. The default setting is
Medium
