BACKLIGHT COMPENSATION (BLC)
If a bright backlight is present, the subjects in the picture may appear dark or as a silhouette.
Backlight compensation 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.
There are two backlight compensation settings:
OFF (default): Backlight compensation is not activated.
ON: Backlight compensation is activated.
If backlight compensation is ON, decrease the auto iris level setting and adjust the auto IR level
to a darker setting. Refer to Auto Iris Level on page 43 and Auto IR Level section on page 41.
VIDEO LEVEL
Set the video output to one of the following options:
NORMAL: 1.0 Vp-p.
HIGH (default setting): 1.2 Vp-p. to compensate for losses in video cable.
