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/lens
assembly away from the dome, see Figure 4-2
on page 16. The camera and PTT bracket can
also be rotated horizontally, see Figure 4-3 on
page 17. The camera alignment can be adjusted
by twisting the PTT disc, see Figure 4-4 on
page 18. Zoom and Focus adjustments can be
made as shown in Figure 4-5 on page 19.
Refer to Figure 4-1 on page 15 for an overview
of directional viewing.
