Noise reduction
■ Enable noise reduction: Check to enable noise reduction in order to reduce noises and ickers
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.
WDR enhanced
This refers to the Wide Dynamic Range function that enables the camera to capture details in a
high contrast environment. Use the checkbox to enable the function, and select the strength of
the WDR functionality, depending on the lighting condition at the installation site. You can select
a higher effect when the contrast is high (between the shaded area and the light behind the
objects).
