It refers to the upper limit value of liming image signal amplicaon. It is recommended to
set a high gain if the illuminaon is not enough, and set a low gain if the illuminaon is
enough.
3D DNR
Digital Noise Reducon (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
Spaal 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
me 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.
Enable Slow Shuer
This funcon can be used in underexposure condion. It lengthens the shuer me to ensure
full exposure. The higher Slow
Shuer Level is, the slower the shuer speed is.
Video Standard
Select the video standard according to the actual power supply frequency.
6.3 Set ICR
ICR adopts mechanical IR lter to lter IR in the day to guarantee the image eect, and to remove
the IR lter at night to guarantee full-spectrum rays can get through the device.
Steps
1.
Go to Conguraon → Device Conguraon → Image Parameters → ICR .
2.
Select ICR Mode.
Auto-switch
Switches to ICR mode automacally at night or in dark light condions.
Manual Switch Select Day/Night Mode to switch to the day or night manually.
Scheduled Switch Set day/night mode, start me, and end me to switch to ICR mode only
during the set me period.
3.
Click Save.
6.4 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
informaon is less
focused.
