4. LENS: DIRECTIONAL, FOCUS, and
“AUTO-IRIS”
ADJUSTMENTS
For optimum picture quality the camera lens
must be as close as possible to the dome’s
inside face, without touching.
The lens and inside dome clearance as well as
the camera’s directional adjustment can be
achieved through the use of the PTT adjustment
bracket attached to the housing base.
Refer to
Figure 4-2
,
Figure 4-3
, and
Figure 4-4
on pages 17, 18, and 19 respectively.
The installer must determine whether the lens
needs to be adjusted once the camera’s viewing
angle has been finalized.
For the “Vari Focal” Auto-Iris Lens: Focal and
Zoom adjustments are shown in
Figure 4-5
on
page 21.
