Set WDR Level. The higher the level is, the higher the WDR strength is.
Time
Enable WDR according to the time.
Brightness
Set Light Threshold. When the brightness reaches the threshold, WDR will be enabled.
BLC
If you focus on an object against strong backlight, the object will be too dark to be seen
clearly. BLC compensates light to the object in the front to make it clear.
Brightness Enhancement at Night
The scene brightness will be enhanced at night automatically.
Enable Defog
Enable defog to get a clear image in foggy days.
Light Compensation on License Plate
Check it. The light compensation on license plates can be realized, and various light

supplement light correction coefficient. The higher the sensitivity is, the easier this function
can be enabled.
Enable Gamma Correction
The higher the gamma correction value is, the stronger the correction strength is.
Brightness
It refers to the max. brightness of the image.
Contrast
It refers to the contrast of the image. Set it to adjust the levels and permeability of the image.
Shutter Speed
If the shutter speed is quick, the details of the moving objects can be displayed better. If the
shutter speed is slow, the outline of the moving objects will be fuzzy and trailing will appear.
Gain
It refers to the upper limit value of limiting image signal amplification. It is recommended to
set a high gain if the illumination is not enough, and set a low gain if the illumination is
enough.
3D DNR
Digital Noise Reduction (DNR) reduces the noise in the video stream.
In Normal Mode, the higher the 3D DNR Level is, the stronger the noise will be reduced. But
if it is too high, the image may become fuzzy.
In Expert Mode, set Spatial Intensity and Time Intensity. If the special intensity is too high,
the outline of the image may become fuzzy and the details may lose. If the time intensity is
