It refers to the contrast of the image. Set it to adjust the levels and permeability of the
image.
Shutter
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.
Hue Range
Select the range to adapt to the display.
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 space domain intensity is
too high, the outline of the image may become fuzzy and the details may lose. If the time
domain 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.
Video Standard
Select the video standard according to the actual power supply frequency.
Power Synchronization
Power Synchronization
The street lights and traffic lights will cause image flashing in live view. Check it, and set
Phase Position and Signal Frequency to overcome the image flashing in live view.
3. Optional: Click Capture Test to check the image.
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.
Before You Start
Please check the video encoding type. ROI is supported when the video encoding type is H.264 or
H.265.
