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 select
Default
mode or
Customized mode.
●
When in Default mode, the system adjusts exposure according to
ambient lighting condition automatically to ensure the clarity of
the darkest area.
●
When in 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.
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.
