Plane of Focus
The lens has rotational focus control that allows the focal length of the lens to be adjusted manually. Depending on the chosen physical location for your camera, it is likely that several planes of focus will exist throughout the full focusing depth of the unit; consequently, the Status Indicator is likely to display green - indicating a good level of focus - several times throughout the full travel of the lens assembly.
Focusing Procedure
