External Day/Night Infrared
Colour 1/3" CCD Camera
The CCT651-657 range of external day/night colour
cameras use a high sensitive 1/3" CCD sensor and
solid-state circuitry which provide long life and high
reliability. They offer excellent image quality with
built in IR illuminator for night vision and a true
Day-Night motorised filter. The cameras are supplied
complete with a tough lockable bracket and can
effectively see in complete darkness up to about 15
meters. They can be used in extreme conditions such
as fire and terrorist attack and have been passed for
underwater test for 24 hours to guarantee
condensation free operation.

POWERING THE CAMERA
Powering 12v DC models CCT651 and CCT652
The 12v DC cameras require a power supply that has a continuous rating of at least 600 mA to cater for the
infra-red capability. It is recommended that a 1 amp power supply or higher are used and that they are well
regulated and provide a smooth 12v DC output. The power supply used must not be a security type used in
intruder alarms as the over voltage may damage the camera and void the warranty. These cameras are
supplied with a 12" waterproof cable out with a 4 pin din connector and a 48" extension lead with a
corresponding 4 pin din female connector with the lead terminated with a BNC female male DC jack plug
for 12v DC power in.
Powering 24v AC models CCT656 and CCT657
If you are using the either of the 24v AC models CCT656 or CCT657 you will need a 24v power supply unit
to power them. As the 48"extension cable supplied has a BNC and power connection attached it is
recommended that the RG59 composite cable is utilised.
Video Out
The video out from the camera is provided by the 4-pin din connector and the use of the 48" extension lead
provides a waterproof connection. There are two connections for video, the video connection and the 0v
ground connection. At the BNC end, the inner core provides the video connection and the outer core of the
braid of the co-ax provides the 0v ground connection.
Dip Switch Settings for CCT651/CCT656 Panasonic Cameras
These cameras have a 4 pin dip switch function adjustment. This is accessible by opening the back of the
camera by turning the large screw anti-clockwise. To avoid damaging the screw it is advisable to use a coin.
Varifocal lens adjustments can be made externally.

opened to its maximum without creating too bright a picture. This then allows the iris to be open as much
as possible for the best low light situations.
BLC - Backlight Compensation
This helps the camera when it is looking at a bright image such as an external window. The BLC tries to
compensate for the bright part of the image so that some of the surrounding area is not too dark.
MIR -Mirror
Setting this switch to OFF sets the mirror function on. This will reverse the video image to a mirror
image.
APT -Automatic Picture Translation Produces sharp or soft quality images.

Troubleshooting Guide
These cameras are built to the highest standards and every unit is tested prior to packing. If you
experience an installation problem you first need to check your cabling, connections, power supply and
monitor.
No picture or a poor picture
The camera cannot function without the correct working power supply. The power supply must be
regulated and be capable of supplying 1A per camera continuously.
For 12v DC cameras check that the power supply is functioning correctly using a multimeter set on DC
voltage (above 12v) and connect the probes to the power supply's output plug or terminal strip. The
meter reading should be between 12 - 13 volts. If a negative voltage is read then either the power supply
is incorrectly wired or the multimeter leads have been reversed in error. If the reading is over 13 volts
DC you may be using an unregulated power supply, which can damage the camera. If the voltage is
under 12 volts it has been known for a camera to work perfectly during the daytime without using the
infrareds but not allowing the infrareds to operate during the night.
If you get a black or very dark picture it could be that the lens iris is not opening properly. Ensure that
the dipswitch settings match those shown in the above diagrams according to model type and adjust the
Automatic Exposure Control (AEC) as per instructed above.
Make sure that the video lead that you connect between the camera and the monitor has no shorts or
open circuits. If you are making your own lead ensure that you have two connections for video i.e. video
and ground as the camera will not function correctly. Faulty leads are generally the most common
problem found when connecting cameras.

Waterproof Infrared Camera INSTRUCTIONS
Interference on the camera picture
Interference is usually caused by poor or inadequate cabling, not observing correct wiring techniques or
not using a regulated power supply. If you want a good quality picture ensure that you do not use an
intruder alarm power supply unit with 12-volt cameras.
Poor performance in low light
This can be due to an incorrect setting and may need adjustment of the AEC control. See above
instructions on ALC setting.
Too bright picture
This can be due to an incorrect setting and may need adjustment of the AEC control. See above
instructions on ALC setting.
