4.2.3 Focal length and focus
Before adjusting the focal length or focus, place the lens
adjustment cap on the lens to ensure that the image sharpness
is the same as when the dome is in place.
1. Connect a monitor or other display device to either the
camera’s BNC connector or to the optional cable (S1460)
on the monitor jack. (If S1460 is connected, there is no
signal on the BNC connector.)
2. Press and hold the menu/select (center) button until the
Install menu appears.
– The Set focus item is highlighted. Do not change this
selection as the camera is now in a special mode for
adjusting focus.
3. To set the field of view of the varifocal lens, loosen the
focal length screw and turn the mechanism until the
required view is displayed on the monitor. (Image goes out
of focus.)
4. Focus the image on the monitor by loosening the focus
screw and turning the mechanism until the image is in
focus.
5. Re-adjust the focal length if necessary.
6. Repeat these two adjustments until the desired view is in
focus.
7. Tighten both screws.
8. Use the navigation buttons to move to Exit and press the
center button until the menu disappears.
9. Remove the lens adjustment cap from the lens and
disconnect the monitor.
4.2.4 Heater
When using the camera at low temperatures, set the heater
setting to Auto in the Install menu. The heater turns on at
ambient temperatures below 0°C (+32°F).
