Introduction
This camera is especially designed for the Philips Observation System. It can be used in
combination with a system monitor (System, Quad or Slave). The System and Quad monitor
provides input for up to 4 cameras. The slave monitor can handle 1 camera in a stand-alone
configuration. The camera has a standard camera mount allowing installation on, for example, a
tripod or wall bracket.
Power supply:
The safe low voltage (16-32V _) for the camera and system accessory is supplied by the monitor
through the system cable. If the length of the system cable is more than 200m/600ft a mains
power adapter should be used to provide the camera power supply.
Camera accessories:
The following camera accessories are available:
•Auto-iris lens 4mm (F1.2)
•Auto-iris lens 8mm (F1.2)
•Protective camera housing
•Mains power adapter

Installation
This chapter describes the installation of the camera. For more detailed information about the
installation and operation of the system monitor and accessories (optional) you should consult
the monitor and/or accessory manuals.
Remark: 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.
Use the power switch to switch off, only operating the power save key is not sufficient. If switching off is
impracticable, use the auto install option of the system monitor’s install menu.
Caution: Never touch the glass of the camera lens as this may cause damage.

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 about 30 seconds or when a key is pressed the camera
image will appear on the monitor screen.
5 If necessary adjust contrast T/brightness (and/or colour S(controls at the front of the
monitor) to optimise the camera image.

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. allowed 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.
Outdoor use
For outdoor use a protective cover has to be used to
protect the camera.
Remark: When the camera is used outdoors an auto-iris lens
is recommended.
Using a different lens
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 figure below).
Lenses available are:
4mm/F1.2 lens
8mm/F1.2 lens
4mm/F1.2 auto-iris lens
8mm/F1.2 auto-iris lens
The cameras are supplied either with the 4mm
or 8mm lens.
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).

Changing a lens
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.
Remark: If an auto-iris lens is used, connect the auto-iris cable to the camera (5).
