Installation Instructions
CAUTIONS
In order to avoid damaging the camera note the following points:
1) The camera has threaded mounting points on the top and bottom of the case.
Only use a standard, photographic, mounting-bolt with a 1/4” 20 UNC thread.
2) Before fitting the lens make sure that its back will not touch the CCD sensor or
associated components when screwed fully home.
3) Do not touch the image-surface of the sensor. If the sensor is accidentally
touched, only clean it using ethyl alcohol.
4) Do not expose the camera sensor to very bright light over a long period of time
as this may cause damage to the CCD. The camera and lens set-up must be
correct to avoid continual over exposure by bright light.
5) The weight of your camera is 0.5kg (0.35kg for low voltage versions).
6) Only use your camera in a clean, dust-free environment.
7) For outdoor use, an appropriate protective housing conforming to IP65 or UL50
or better must be used.
POWER SUPPLY
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. Only
power low voltage cameras from a class 2 isolated power supply. The typical power
consumption of a VP... 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 98 to 260 VAC at 50 Hz for CCIR/PAL (60Hz for EIA/NTSC).
REFER TO THE WIRING INSTRUCTION LABEL ATTACHED TO THE SUPPLY CORD and terminate
the cord with the appropriate circuit fitted with a 3A fuse.
MAINS CAMERAS MUST BE CONNECTED TO A PROTECTIVE EARTH GROUND. 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 11-40 VDC and
14-30 VAC. Connections and polarity are indicated above the screw terminals on the rear
panel. The power supply must be a class 2 isolated type.
