zD/N Level
The D/N level is the light level at which the IR cut filter switches DAY or NIGHT. Three levels are selectable: HIGH, MID and LOW.
The default setting is MID.

zSharpness
The sharpness function enhances picture detail by increasing the aperture gain of the camera and sharpening the edges in the picture.
Levels from 1 to 16 are selectable, with the default setting of level 9.
zBLC/WDR
If a bright backlight is present, the subjects in the picture may appear dark or as a silhouette. Backlight compensation (BLC) enhances
objects in the center of the picture. The dome uses the center of the picture to adjust the iris. If there is a bright light source outside of
this area, it will wash out to white. The camera will adjust the iris so that the object in the sensitive area is properly exposed.
When the Wide Dynamic Range (WDR) function is on, the dome is able to balance the brightest and darkest sections of a scene to
produce a picture that is better balanced in lighting and provides more details.
Note: The BLC/WDR feature varies depending on camera model. The default setting is for BLC function.
