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.
Enable electronic image stabilizer
If you experience problems such as vibration on a pole mount, try enable the image stabilizer. •
EIS allows users to adjust focal length manually to enhance the EIS performance when connected
to manual lens
Highlight mask
■ If there is a strong light source in your application, e.g., light pole, enable this function to avoid
negative interference.
Scene mode: deblur
■ When enabled, shutter time will be xed to 1/120 second to reduce image smear. This feature
is designed to apply with human movement at the pace of 1.4~2.2m/s. The deblur function
is related to Motion detection where motion-alerted pixels need to be suppressed in order to
increase the accuracy of motion detection. In certain conditions, shadows or light changes can
all cause false alarms in motion detection.
The deblur function uses the same detection window as that of the Motion detection.
