The current consumption of the camera is 200 mA.
7 Operation
1) After applying the operating voltage, the camera is
ready for operation.
2) After switching on the monitor, align the camera to
the surveillance zone in such a way that the lenses
of the lens assembly are not exposed to direct sun-
light, otherwise the CCD image sensor chip might
be damaged!
3) Adjust the distance on the lens. In case of a lens
with manual iris control, adjust the iris to optimum
picture reproduction (depth of focus and bright-
ness).
4) If the picture is not sharp despite a correctly ad-
justed distance, readjust the mechanical focus set-
ting for the lens. For this purpose, release the set-
screws (8). Bring the picture into focus by turning
the threaded ring (together with the lens and the
adapter ring, if required). Then retighten the
screws.

5) In case of a DC controlled lens, the operating point
of the control can be readjusted if the picture is too
dark or too bright: Adjust an optimum brightness by
turning the control LEVEL (3) with a small screw-
driver. When using a lens with video signal control-
led iris, the controls can be found on the lens.
6) Adjustment of the DIP switches (6)
GAMMA 1/GAMMA 2 (gamma correction)
The standard adjustment is GAMMA 1 for a grey
scale conversion of 0.45. If an optimum adjust-
ment of the contrast on the monitor is impos-
sible, set the switch to the position GAMMA 2.
AGC (automatic gain control)
The standard adjustment is AGC MIN. In case
of great variations in the luminous intensity, it
may be possible to obtain an optimum control
by the camera in the position AGC MAX.
SHUTTER (electronic shutter)
The standard adjustment for lenses with iris con-
trol is OFF. In case of sufficient brightness and
fast-moving objects, enhanced focussing can be
obtained in the lower position SHUTTER.
