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 strength (low, medium, high) to reach the best image quality.
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
Profile
to adjust all settings above in a pop-up window.
Activated period: Select the mode this profile to apply to: Day mode, Night mode, or Schedule
mode. Please manually enter a range of time if you choose Schedule mode. Then check
Save
to
take effect.
Noise reduction: In low light conditions where electronic gains are applied to reveal more details,
noises may also increase. Select this option to reduce noises in images. Noise reduction, a.k.a., 3D
Noise Filter, decreases noises on images and hence reduces the bit rate consumed and also helps
with smooth streaming.
Note that with fast moving objects in dark environments, trailing smears may occur when this
function is enabled.
