Backlight Settings
 BLC (Back Light Compensation)
If there’s a bright backlight, the subject in front of the backlight appears silhouetted or dark.
Enabling BLC (back light compensation) function can correct the exposure of the subject. But the
backlight environment is washed out to white.
 WDR (Wide Dynamic Range)
The wide dynamic range (WDR) function helps the network positioning system provide clear
images even under back light circumstances. When there are both very bright and very dark areas
simultaneously in the field of view, WDR balances the brightness level of the whole image and
provide clear images with details.
You can enable or disable the WDR function as shown in Figure 6-31. The wide dynamic level
ranges from 0 to 100.

 HLC
HLC (High Light Compensation) makes the network positioning system identify and suppress the
strong light sources that usually flare across a scene. This makes it possible to see the detail of
the image that would normally be hidden.
White Balance
The White Balance mode can be set to Auto, MWB, Outdoor, Indoor, Fluorescent Lamp, Sodium
Lamp and Auto-Tracking.
 Auto:
In Auto mode, the network positioning system retains color balance automatically according to
the current color temperature.
 Manual White Balance:
In MWB mode, you can adjust the color temperature manually to meet your own demand as
shown in Figure 6-32.
