Colour Observation Camera
Table of contents
Read these instructions, before taking your system in operation.
This camera is especially designed for the colour Philips Observation Systems. It combines a high sensitivity sensor with advanced digital signal processing, resulting in a high quality camera with excellent performance under even difficult circumstances. The camera has a standard camera mount allowing installation on, for example, a tripod or wall bracket.
Camera accessories:
The following camera accessories are available:
• Protective camera housing for protection against dust and theft
• Weather proof housing for outside use
• Extension system cables
• Mains power adapter for providing additional power to the camera at large distances

This chapter describes the installation of the camera. For more detailed information about the installation and operation of the system monitor you should consult the monitor manuals.
Remarks:
* When the system configuration is altered, the system monitor needs to check and memorise the cameras
and accessories connected to its inputs. This is done automatically when the power is switched on (rear switch).
* This system uses a 4 wire twisted pair telephone type cable. The use of the correct twisted pair cable can
be critical to operation, especially at larger cable lengths.
Caution: Never touch the glass of the camera lens as this may cause damage.

Installation
1. Take the camera, system cable and monitor to the area you want to observe (with the monitor on site, you can check whether the camera covers the required area).
Remark: For outdoor use protective camera housing has to be used to protect the camera from rain and snow.
2. Connect the camera to the system monitor (1).
3. Connect the system monitor to the mains (2).
4. Switch on the mains power switch (3).
The monitor will check the system. After a short time the camera image will appear on the monitor screen.
5. If necessary adjust contrast /brightness and/or colour (controls at the front of the monitor) to optimise the camera image.
6. Hold the camera at the proposed installation position.

7. Check on the monitor whether the camera covers the required area (The best results are obtained when the camera is pointed slightly downwards and is not looking into a bright light source). Adjust focus if necessary.
8. Fasten the wall bracket (1) to the wall, or another even and firm surf ace.
9. Tighten the knob (2).
10. Fasten the camera to the bracket (3).
11. Loosen knob (4) and screw (5) slightly (figure below).
12. Direct the camera at the object or area you want to observe (8). Check the camera image on the monitor. Adjust focus if necessary.
13. Tighten the knob (4) and screw (5) when the camera is in position.
14. Check if the cable length compensation (6) selector is set to the correct length. The length set must be the same as the length of the system cable (0-300m/900ft max.) connecting monitor and camera.
Remark: If the length of the system cable is more than 200m/600ft, a mains power adapter (optional should be used (the max. cable length is 300m/900ft). Connect the adaptor to the mains and to the external supply socket (7) at the back of the camera.

Focus adjustment
• Adjust the focus ring of the camera lens to obtain optimal image sharpness.
Remark: If still no sharp object image is obtained, you should adjust the back-focus of the camera.
Back-focus adjustment
Caution: Back-focus adjustment is only necessary when no sharp object image is obtained with the focus adjustment ring.
• Set focus adjustment ring to Far or Infinity (1).
• Aim the camera at an object at least 15 metres/45 feet away.
Remark: When bright light sources are positioned within thecamera view field; dim the light source.
• Loosen the back-focus locking ring (2).
• Rotate the lens, including the CS-mount ring, until the video image on the monitor is sharp.
• Tighten the back-focus locking ring (2), while keeping the lens in place.
Camera sound on/off
Use switch (9) to enable or disable the built-in camera microphone.
The camera switches to specific settings optimised for outdoor use when connecting an auto-iris lens. For outdoor use a protective cover has to be used to protect the camera.
When the camera is used outdoors an auto-iris lens is recommended.

The CS-mount of the camera allows you to use other lenses. The field of view (= covered area) of an 8mm lens is half of the field of view of the 4mm lens (see f igure below).
The auto-iris lenses are recommended when the camera is used in environments with variable light conditions (eg. outdoors). By means of the auto-iris the amount of light going through the lens is regulated. The auto-iris is DC-controlled through a 4-pole connector at the back of the camera (3).
Perform the following steps to change a lens:
• Point the camera downwards. This to minimize possible deposit of dust on the inside of the camera when the lens is removed.
• Remove the old lens by turning it counter-clockwise (1). Do not release the back-focus locking ring (2), otherwise you may have to readjust the back-focus of the camera.
Caution: Never touch the CCD sensor which is located at the inside of the camera. Only use clean, dry air to blow particles from the surface of the sensor.
• Mount the new lens by turning it clockwise onto the lens mount of the camera.
• Direct the camera at the object or area to be monitored (6).
• Tighten the knob (3) and screw (4) when the camera is in position.
• Adjust the focus ring (1) of the camera lens to obtain an optimal image sharpness.
If an auto-iris lens is used, connect the auto­iris cable to the camera (5). Switch the system on and off to setup the camera with specific outdoor settings.

For the interconnections between the system monitor and camera 25m/75ft system cable is supplied. For an optimum picture and sound quality you should always use 4-wire dual twisted­pair cable when extending the connection. The max. allowed cable length is 300m/900ft. The cable and plugs are available in the hobby and professional trade. Pay attention that the connectors are fixed to the cable corresponding to the figure.
If the cable length between the monitor and camera is more than 200m/600ft a mains power adapter should be used (see accessories).
Caution: The plugs used for the observation system have the same dimensions as standard telephone plugs. Never connect a telephone to the camera or system monitor.
Cleaning
You can clean the outside of the camera with a moist fluff-free cloth or shammy leather cloth.
When cleaning the camera lens a special cleaning cloth should be used. Do NOT use cleaning fluids based on alcohol, methylated spirit, ammonia, etc..
Never touch the glass of the camera lens to prevent its delicate coating from damaging. Avoid direct contact with water.
