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.
SSA
Enable SSA, the system automatically adjusts the image brightness
according to the environment to make the objects in the image clearer.
