to enter the following interface.

IRCUT Mode

4 modes: GPIO Auto, Video Auto, Color Mode and Black & White Mode.
IR-CUT Delay
：
Set IRcut delay switching time
Image flip
：
Lens flip and angle flip
Back light
：
Enable or disable the Back light. When enabled, there are three levels: low, middle and
high.
Back light compensation can compensate the darkness of the subject caused by shooting against the
sunlight. In some application scenario, the field of view may contain a very bright background field,
such as the door and window against the light, while the observed subject is surrounded by the bright
field. In this case, the photo is gloomy and has no layering. The backlight compensation can be
applied to solve the problem.
3D Noise Reduction
：
Enable (auto or manual) or disable the video noise reduction function. Default
setting is Auto.
WDR
：
Enable or disable WDR function.
WDR is a technology that enables the camera to catch the image features with strong contrast.
In short, DR (dynamic range) is the details of the bright part and dark part of image. The larger
dynamic range shows richer layers and broader color space.
