Section 4. Directional Adjustment - Bosch EX40 Installation Instructions Manual

4. DIRECTIONAL ADJUSTMENT
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/lens
assembly away from the dome. See Figure 4-2
on page 19. The camera and PTT bracket can
also be rotated horizontally by loosening the
base adjustment knob. See Figure 4-3 on
page 20.
The camera picture can be adjusted by twisting
the PTT disc. See Figure 4-4 on page 21.
Refer to Figure 4-1 on page 18 for the
explanation of directional viewing.
