Note :
Reason for facing the camera down.
The Zoom-Lens unit has a moving lens inside. This
moving lens requires a tolerance (10 µm order) when
starts to move.
Because of 1/4" CCD and x22 zooming raito, the toler-
ance will affect the focal point.
When adjusting the camera with the Lens facing down,
the tolerance will be always pulled downward by the
gravity, which makes it possible to adjust back foccus
as the best.
