Defog: Defog helps improve the visibility quality of captured image in poor weather conditions such as
smog, fog, or smoke.
Note that the Preview button has been cancelled, all changes made to image settings is directly shown
on screen. You can click Restore to recall the original settings without incorporating the changes. When
completed with the settings on this page, click Save to enable the setting. You can also click on Prole
mode to adjust all settings above in a pop-up window for special lighting conditions during a specic
period of time in a day.
Enable 3D 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.
Electronic image stabilizer
Select the checkbox to enable the Electronic image stabilization (EIS) function at installation sites where
vibration is expected, such as a train station.
Sensor Setting 2:
For customized situations such as
night mode.
Scene mode: deblur
■
When enabled, shutter time will be fixed 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.
