Backlight Settings
BLC
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 camera 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 6-33. The wide
dynamic level ranges from 0 to 100.
This function varies depending on the models of speed dome.
HLC
HLC (High Light Compensation) makes the camera 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.

Lamp, Sodium Lamp and Auto-Track.
