Section 4. Camera/Led Adjustments - Bosch EX49N Installation Instructions Manual

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.
