Network Traffic Camera (for Traffic Flow Camera) User Manual
The higher the gamma correction value is, the stronger the correction 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.
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.
3D Noise Reduction Mode
Digital Noise Reduction (DNR) reduces the noise in the video stream.
In Normal Mode, the higher the Noise Reduction 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 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
You can enable slow shutter to increase the exposure time and raise the photosensitivity.
Then the image brightness can be raised in low illumination conditions.
Video Standard
Select the video standard according to the actual power supply frequency.
