4. CAMERA / LED ARRAY,
ADJUSTMENTS.
For optimum picture quality the camera lens
must be as close as possible to the dome's
inside face, without touching. However, the foam
ring around the lens should be adjusted to seal
against the dome, minimizing any side light
interference, but without obstructing the field of
view.
The lens dome clearance and camera viewing
angles can be achieved through a combination
of adjustments available on the PTT bracket.
For example: If the lens touches the dome,
loosen the side adjustment knobs and slide the
Camera/LED Array assembly away from the
dome. See Figure 4-2 on page 18.
The Camera and PTT bracket can also be
rotated horizontally by loosening the base
locking knob. See Figure 4-3 on page 19.
The camera picture can be adjusted by twisting
the PTT disc. See Figure 4-4 on page 20.
The LED Array brightness has been set at the
factory before shipment.
For photocell brightness adjustment see
Figure 2-2 on page 8.
