Set Icr; Set Roi - HIKVISION iDS-TCH44P-B User Manual

Network Traffic Camera (Multi-lens LPR Camera) User Manual
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 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.
Enable Slow Shutter
This function can be used in underexposure condition. It lengthens the shutter time to ensure
full exposure. The higher Slow Shutter Level is, the slower the shutter speed is.
Video Standard
Select the video standard according to the actual power supply frequency.

6.3 Set ICR

ICR adopts mechanical IR filter to filter IR in the day to guarantee the image effect, and to remove
the IR filter at night to guarantee full-spectrum rays can get through the device.

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 information is less
focused.
Switches to ICR mode automatically at night or in dark light conditions.
Select Day/Night Mode to switch to the day or night manually.
