■ Sharpness: Adjust the image sharpness level, which ranges from 0% to 100%. 

■ Gamma curve: Adjust the image sharpness level, which ranges from 0.45 to 1, from Detailed to 

Contrast. You may let firmware 

Optimize your display or select the Manual mode, and pull the slide bar 

pointer to change the preferred level of Gamma correction towards higher contrast or towards the higher 

luminance for detailed expression for both dark and lighted areas of an image. 

■ Noise reduction

■ Enable noise reduction: Check to enable noise reduction in order to reduce noises and flickers in 

image. This applies to the onboard 3D Noise Reduction feature. Use the pull-down menu to adjust 

the reduction strength. Note that applying this function to the video channel will consume system 

computing power.

  3D Noise Reduction is mostly applied in low-light conditions. When enabled in a low-light condition 

with fast moving objects, trails of after-images may occur. You may then select a lower strength level 

or disable the function. 

You can click on 

Restore to recall the original settings without incorporating the changes. When 

completed with the settings on this page, click 

Save to enable the setting. 

The following applies to a fixed-focal lens module:

■ Enable low light compensation: Select this option in low light mode, and the values of sharpness and 

brightness will change automatically. This function also benefits from an automated noise reduction 

feature.

■ WDR enchanced: This function allows users to identify more details of objects in the high contrast 

environment especially for details in the shaded area. You may check the 

Enable WDR enhanced 

checkbox, and then adjust the sensitivity (low, high) and the strength (low, medium, high) to reach the 

best image quality.
