Image Adjustment
Select the camera and then click “Image Adjustment” to go to image adjustment tab. Refer to
the above picture. Drag the slider to set the camera’s brightness, contrast, saturation and hue
value. Check sharpen, wide dynamic and denoise and then drag the slider to set the value. Click
“Default” button to set these parameters to default values.
The introductions of these parameters are as follows:
Parameter Meaning
Brightness It is the brightness level of the camera’s image.
Contrast It is the color difference between the brightest and darkest parts.
Saturation It is the degree of color purity. The color is purer, the image is brighter.
Hue It refers to the total color degree of the image.
Sharpen
It refers to the resolution level of the image plane and the sharpness level of the
image edge.
Wide Dynamic
The wide dynamic range (WDR) function helps the camera provide clear images
even under back light circumstances. When there are both very bright and very
dark areas simultaneously in the field of view, WDR balances the brightness level
of the whole image and provide clear images with details.
Denoise
Decrease the noise and make the image more thorough. Increasing the value will
make the noise reduction effect better but it will reduce the image resolution.
