The higher the gamma correcon value is, the stronger the correcon 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.
Shuer
If the shuer speed is quick, the details of the moving objects can be displayed beer. If the
shuer 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 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 Noise
Reducon Mode
Digital Noise Reducon (DNR) reduces the noise in the video stream.
In Normal Mode, the higher the Noise Reducon Level is, the stronger the noise will be
reduced. But if it is too high, the image may become fuzzy.
In Expert Mode, set Space Domain Intensity and Time Domain 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
You can enable slow shuer to increase the exposure me and raise the photosensivity.
Then the image brightness can be raised in low illuminaon condions.
Video Standard
Select the video standard according to the actual power supply frequency.
5.3 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.
