Camera Connection - Monacor TVCCD-623 Bedienungsanleitung

6 Camera Connection

Connect the BNC jack "VIDEO OUT" (7) to the video
input of the following unit (e. g. monitor, camera switcher,
video splitter) via a 75 Ω cable (e. g. MONACOR VEC-
62/10). With a cable length exceeding 100 m, a video
amplifier should be inserted between the camera and
the cable to compensate cable losses.
Connect the plug of the mains cable (8) to a socket
(85 – 265 V~/50 Hz).
7 Operation
1) After connecting the camera to the power supply, it is
ready for operation. The red LED "POWER" (10) on
the rear side of the camera lights up.
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 brightness).
4) If the picture is not sharp despite a correctly adjusted
distance, readjust the mechanical focus setting for
the lens. For this purpose, release the setscrew (2)
and adjust a sharp picture by fine adjustment of the
rotating ring (3). Then retighten the screw.
5) In case of a lens with automatic iris control, the video
signal level of the iris control can be readjusted if the
picture is too dark or too bright:
When using a DC lens, adjust an optimum video
level by turning the control "DC LEVEL" (5) with a
small screwdriver. In case of a lens with video signal
controlled iris, the level control for the video signal
can be found on the lens.
7.1 Adjustment of camera functions
Picture synchronization
With the DIP switch (9a) set to "INT", the camera is
synchronized via an internal clock generator (stand-
ard adjustment when using a single camera).
With the switch set to "LL" ("Line Lock"), the
mains frequency will synchronize the change of pic-
tures; this adjustment is required when several
cameras are used (e. g. in systems with camera
switchers, multiplexers). In case of vertical rolling of
the picture at the moment of camera change-over,
adjust a steady picture by turning the phase adjust-
ing control (11) with a small screwdriver.
AGC (automatic gain control)
Use the DIP switch (9b) to adjust the gain factor for
the automatic gain control – to increase the video
signal level in case of poor illumination. The standard
adjustment is "AGC". In case of great variations in
the luminous intensity, it may be possible to obtain
