Smart Supplement Light
This feature uses smart image processing technology to reduce overexposure caused by supplement light.
IR Light Mode
When the mode is set to Auto, the supplement light is automatically enabled or disabled according to the image brightness.
Brightness Limit

VI. 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.
VII. 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.
Note
When WDR is enabled, some other functions may be not supported. Refer to the actual interface for details.
VIII. White Balance
White balance is the white rendition function of the camera. It is used to adjust the color temperature according to the environment.
IX. DNR
Digital Noise Reduction is used to reduce the image noise and improve the image quality. Normal and Expert modes are selectable.
Normal
Set the DNR level to control the noise reduction degree. The higher level means stronger reduction degree.
