Installation Instructions
PRODUCT SAFETY
• Installation and servicing is only to be carried out by suitably qualified and
experienced personnel,
• Mains cameras contain hazardous voltages,
• Do not remove covers as there is a risk of injury or death by electric shock,
• Cameras connected to mains supplies must be earthed,
• Only power low voltage cameras from a class 2 isolated power supply,
This camera range is designed for use in general purpose CCTV applications and has no other
purposeꢀ Only operate your camera between the temperatures of -10OC and +50OCꢀ Do not
operate your camera outside its specified power supply rangeꢀ Cameras must only be used in
clean, dry, dust-free environments unless housed in suitable protective housings to IP65 or
betterꢀ

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 inAC mains andAC and DC low voltage typesꢀ The voltage required
to operate the camera is clearly marked on the rear panel of the cameraꢀ Only
power low voltage cameras from a class 2 isolated power supplyꢀ The typical power
consumption of a VPꢀꢀꢀ series camera is less than 5 Wattsꢀ
Mains Power Supply
Cameras that are intended to operate directly from the mains supply are fitted with a non-
detachable power supply cordꢀ The voltage of operation is clearly marked on the rear panel of
the cameraꢀ Generally this is 98 to 260 VAC at 50 Hz for CCIR/PAL (60Hz for EIA/NTSC)ꢀ
REFERTOTHEWIRINGINSTRUCTIONLABELATTACHEDTOTHESUPPLYCORDandterminate
the cord with the appropriate circuit fitted with a 3A fuseꢀ
MAINS CAMERAS MUST BE CONNECTED TO A PROTECTIVE EARTH GROUNDꢀEnsurethat
a secure means of isolation from the mains is provided for the camera in accordance with the
national wiring regulations of the country of installationꢀ
Auto-Switching Power Supply
Cameras fitted with an automatic selecting power supply operate between 11-40 VDC and
14-30 VACꢀ Connections and polarity are indicated above the screw terminals on the rear
panelꢀ The power supply must be a class 2 isolated typeꢀ

Default switch positions shown (white represents switch position)
(1) Synchronisation Selection (LL/INT)
This switch is used to select the camera synchronisation modeꢀ When the camera is connected
to anAC supply the Line-lock (LL) mode can be usedꢀ This locks the camera frame rate to the
mains frequency so that cameras in a system are triggered at the same point on the mainsAC
cycleꢀAlso see 5, 6 and 7 Line Lock PhaseAdjustmentꢀ
(2) Backlight Compensation (BLC)
The BLC (Back Light Compensation) facility compensates for back-lit scenes by enhancing
objects in the centre of the scene which would previously have been in silhouetteꢀ Select ON
or OFF using the BLC switchꢀ Default is OFFꢀ BLC will only function with a manual iris lens when
the Electronic Iris facility is switched onꢀ For direct drive and auto iris lenses, BLC will still
function even though the Electronic Iris facility is switched offꢀ
(3) Gamma
Two different gamma correction options are availableꢀ Select Normal (0ꢀ45) to provide increased
visibility in dark areas of the scene, or Linear (1ꢀ0)ꢀ The default setting is Normalꢀ

(4) Electronic Iris (EI)
CONTROLS AND SWITCHES
The Electronic Iris (EI) compensates for excessive light level by automatically adjusting the
shutter speedꢀ The electronic iris should be ON when using fixed or manual iris lensesꢀ When
usingAuto Iris (AI) lenses of either the video drive or DC drive types the EI must be OFFꢀAlso
see (10) Electronic Iris and DC Lens LevelAdjustment Potentiometerꢀ
(5) Line Lock Phase Adjust Potentiometer
When the camera is in line-lock mode it is possible to adjust the point on theAC cycle at which
the camera triggersꢀ This facility is provided so that cameras that are connected to different
mains phases may still be synchronisedꢀ
The line lock phase adjustment potentiometer allows the line lock phase trigger point to be
adjusted by ±120Oꢀ Rotating the potentiometer clockwise advances the trigger point and turning
it anticlockwise retards the trigger pointꢀ The factory default setting is the zero crossing pointꢀ
If all cameras in a system are on the same mains phase then no line lock phase adjustment
should be madeꢀ
(6 and 7) Line Lock Phase Adjust Buttons (+ Advance; - Retard)
When the camera is in line-lock mode it is possible to adjust the point on theAC cycle at which
the camera triggersꢀ This facility is provided so that cameras that are connected to different
mains phases may still be synchronisedꢀ
The line lock phase adjustment buttons allows the line lock phase trigger point to be adjusted by
±120Oꢀ Pressing the advance button advances the trigger point and pressing the retard button
retards the trigger pointꢀ The factory default setting is the zero crossing pointꢀ If all cameras in
a system are on the same mains phase then no line lock phase adjustment should be madeꢀ
(8) Direct Drive/DC Drive Lens Connector
This 4-pin connector supplies the power and DC control signal for use with DC driveAuto Iris
lensesꢀ If the lens does not have a DD plug fitted then wire the lens to a suitable plug in
accordance with the diagram below:

(9) Back Focus Adjustment screws
These two adjustment points located on the camera body top and side (top not shown), are
used to adjust the back focal length or picture focusꢀ The range of adjustment allows both C
and CS mount lenses to be used without the need for a spacer ringꢀ Refer to the section on
FocusAdjustment
(10) Electronic Iris and DC Lens Level Adjustment Potentiometer
If the camera is used with a direct drive (DD) lens this potentiometer varies the DC reference
voltage used to control the lensꢀ The potentiometer has the effect of increasing or decreasing
the lens apertureꢀ This potentiometer should be set to obtain a 1V pk-pk video outputꢀ
If a mono camera (VPM8030, VPM8032, VPM8130, VPM8132, VPM8120 and VPM8122) is used
with a manual iris or fixed iris lens, and hence the electronic iris is switched ON, this potentiometer
controls the electronic iris levelꢀ The potentiometer is factory set to give a 1V pk-pk video

LENS SETUP PROCEDURES
For manual or fixed iris lenses set the EI switch to ONꢀ
Auto Iris Lenses
Switch the EI offꢀ Refer to the lens instructions and adjust the lens for the optimum picture
(video output level of 1V peak-to-peak)ꢀ
Direct Drive Lenses
Switch the EI offꢀ Use an appropriate screwdriver to turn the lens level potentiometer (under
the hinged flap) fully clockwise then back off until the optimum picture is obtained (video output
level of 1V peak-to-peak)ꢀ
FOCUS ADJUSTMENT
The back focus adjustment screws are located on the top and side of the case and should be
adjusted using an appropriate screwdriverꢀ If possible, always use the top screw to adjust the
back focus mechanismꢀ
Turn the adjuster screw clockwise or anticlockwise to obtain focusꢀ When the focus is sharp,
turn the back focus adjustment screw 2 or 3 turns anticlockwiseꢀ The picture will lose sharpnessꢀ
Turn the back focus screw clockwise until focus is once again obtainedꢀ If you have turned the
back focus screw clockwise past the point of best focus, repeat the procedureꢀ The last turn
of the back focus adjustment screw must always be in a clockwise directionꢀ Do not
‘over turn’ the back focus mechanismꢀ
Fixed Lenses
Set the lens focus to infinity and view an image greater than two meters awayꢀ Focus the image
using the back focus screwꢀ Set the lens focus as requiredꢀ
Manual Iris Lenses
Open the iris fully and set the lens focus to infinityꢀ View an image greater than 7 feet (2 meters)
awayꢀ Focus the image using the back focus screwꢀ Set the lens focus and iris as requiredꢀ
