HIKVISION iDS-TCH44P-B

It refers to the upper limit value of liming image signal amplicaon. It is recommended to
set a high gain if the illuminaon is not enough, and set a low gain if the illuminaon is
enough.
3D DNR
Digital Noise Reducon (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
Spaal 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 Shuer
This funcon can be used in underexposure condion. It lengthens the shuer me to ensure
full exposure. The higher Slow
Shuer Level is, the slower the shuer 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 eect, and to remove
the IR lter at night to guarantee full-spectrum rays can get through the device.
Steps
1.
Go to Conguraon → Device Conguraon → Image Parameters → ICR .
2.
Select ICR Mode.
Auto-switch
Switches to ICR mode automacally at night or in dark light condions.
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
informaon is less
focused.
