Smart Supplement Light
This feature uses smart image processing technology to reduce overexposure caused by
supplement light.
Supplement Light Mode
When the mode is set to Auto, the supplement light is automatically turned in or off
according to the image brightness.
When the mode is set to Scheduled, set the start time and end time for the light to work.
When the mode is set to NC, the light is off.
When the mode is set to NO, the light is on.
Brightness Limit
Adjust the upper limit of supplement light power. For devices with both white light and IR
light, white light and IR light brightness limit can be set separately.
Note
The function varies on device settings and device models.
9.2.6 BLC
If you focus on an object against strong backlight, the object will be too dark to be seen clearly.
BLC (backlight compensation) compensates light to the object in the front to make it clear. If BLC
mode is set as Custom, you can draw a red rectangle on the live view image as the BLC area.
9.2.7 WDR
The WDR (Wide Dynamic Range) function helps the camera provide clear images in environment
with strong illumination differences.
When there are both very bright and very dark areas simultaneously in the field of view, you can
enable the WDR function and set the level. WDR automatically balances the brightness level of the
whole image and provides clear images with more details.
