Backlight mode Description
BLC
Enable BLC, the camera can get clearer image of the dark areas on the
target when shooting against light. You can enable or disable
Customized
mode.
●
When you enable
Customized
mode, the system auto adjusts
exposure only to the set area according to ambient lighting condition
to ensure the image of the set area at ideal brightness.
●
When you disable
Default
mode, the system adjusts exposure
according to ambient lighting condition automatically to ensure the
clarity of the darkest area.
WDR
The system dims bright areas and compensates dark areas to ensure the
clarity of all the area. The higher the value is, the brighter the dark will be,
but the more the noise will be.
There might be a few seconds of video loss when the device is switching
to WDR mode from other mode.
HLC
Enable HLC when extreme strong light is in the environment (such as toll
station or parking lot), the camera will dim strong light, and reduce the
size of Halo zone to lower the brightness of the whole image, so that the
camera can capture human face or car plate detail clearly. The higher the
value is, the more obvious the HLC effect will be.
