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 conditions can be adapted via setting license plate expectant brightness and
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
too high, trailing may appear.
2D DNR
The higher the 2D DNR Level is, the stronger the noise will be reduced. But if it is too high,
the image may become fuzzy.
8.3 Set ROI
ROI (Region of Interest) encoding helps to assign more encoding resources to the region of
interest, thus to increase the quality of the ROI whereas the background information is less
focused.
