CDSP9772 Cameras Installation Instructions
PERFORMANCE
CDSP9772 series cameras are designed to give a good image over a broad range of
scene illumination. To achieve this, the cameras operate in colour mode where the scene
illumination is bright and automatically switch to monochrome where the scene illumination
is low. Typically, the switchover occurs at approximately 1.0 lux.
Cameras fitted with optical low-pass filters (suffix /LP) provide improved image quality with
less fringeing. However, colour rendition may, on occasion, be less acurate.
Cameras fitted with optical low-pass filters and IR cut (suffix /WF) provide improved fringe
rejection and colour rendition but have reduced low-light sensitivity.
POWER SUPPLY
CDSP9772 series cameras are available in AC mains and AC and DC low voltage types.
The voltage required to operate the camera is clearly marked on the rear panel of the
camera. The green POWER LED on the rear panel indicates that power is connected.
Only power low voltage cameras from a class 2 isolated power supply. The power
consumption of a CDSP9772 series camera is less than 5 Watts.
Mains power supply
Cameras that are intended to operate directly from the mains supply are fitted with a non-
detachable power supply cord. The voltage of operation is clearly marked on the rear panel
of the camera. Generally this is 230V AC +6% -10% at 50Hz. REFER TO THE WIRING
INSTRUCTION LABEL ATTACHED TO THE SUPPLY CORD and terminate the cord with
the appropriate mains plug fitted with a 3A fuse. MAINS CAMERAS MUST BE CONNECTED
TO A PROTECTIVE EARTH. Ensure that a secure means of isolation from the mains is
provided for the camera in accordance with the national wiring regulations of the country of
installation.
Auto-switching power supply
Cameras fitted with an automatic selecting power supply operate between 11-40V DC and
12-30V AC. Connections and polarity are indicated above the screw terminals on the rear
panel. The power supply must be a class 2 isolated type.
VIDEO CONNECTIONS
To obtain a video output, connect a video coaxial cable terminated with a 75
W
BNC connector
to the BNC socket marked VIDEO OUT on the rear of the camera.
On selected cameras, a means of external synchronisation may be provided - see table 1
for details. For external synchronisation, connect a video coaxial cable terminated with a
75
W
BNC connector to the socket marked GENLOCK on the rear of the camera. The
GENLOCK facility synchronises to either a 1V peak-to-peak video signal or a standard
sync plus blanking signal. A signal connected to the GENLOCK input automatically overrides
all other synchronisation settings.
