Installation Instructions
AUTO-IRIS LENS CONNECTOR
All cameras within the range can be used with lenses fitted with automatic irises (either direct
drive, DC drive or video drive types). The lenses are connected to the camera via a 4-pin
square socket located at the front of the camera. The type of auto-iris lens (either video drive
or direct / DC drive) is selected by a two position switch located behind the doorsee also
Auto-iris lens Selector Switch
.
SEPARATED Y/C VIDEO OUTPUT CONNECTOR
This connector provides a separated Y/C (luminance and chrominance) video output.
COMPOSITE VIDEO OUTPUT BNC CONNECTOR
To obtain a 1.0V [pk-pk] composite video signal, connect a video coaxial cable terminated with
a 75 Ohm BNC connector to the BNC socket marked VIDEO OUT. For cameras with twisted-pair
video outputs, ensure that the Video Output Type Selector switch is set to
CV
see
Video
Output Type Selector switch
.
TWISTED-PAIR VIDEO OUTPUT TERMINALS
(SUFFIX ...TP CAMERAS ONLY)
These terminals provide a composite video output signal which may be transmitted over a
twisted-pair connection to equipment furnished with a suitable receiver. Ensure that the Video
Output Type Selector switch is set to
TP
see
Video Output Type Selector switch
. Remove
the blue connector to connect the twisted pair. Ensure that the connection polarity is observed
in relation to the connected twisted pair receiver.
NOTES:
Cable runs of up to 3000ft (approx. 1km) with an active receiver may be used; 1000ft (300m)
with a passive receiver.
Use unshielded twisted-pair (UTP), Category 2 or better, 24 AWG or thicker, stranded or solid
core.
For safety, do not run the unshielded twisted-pair cable alongside high-voltage carrying cables.
The twisted-pair output cannot be used at the same time as the Composite Video output .
VIDEO OUTPUT TYPE SELECTOR SWITCH CV/TP
(SUFFIX ...TP CAMERAS ONLY)
This switch is used to set the type of video output from the camera. The camera may be set to
Composite (
CV
) or Twisted-pair (
TP
).
