Section 4. Adjustments - Bosch EX49N Installation Instructions Manual

4. 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.
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 15. The Camera and PTT
bracket can also be rotated horizontally, see
Figure 4-3 on page 16. The camera picture can
be adjusted by twisting the PTT disc, see Figure
4-4 on page 17. The LED Array brightness has
been set at the factory before shipment. For
photocell sensitivity adjustments see Figure 2-2
on page 8.
