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).
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 auto-
iris cable to the camera (5). Switch the
system on and off to setup the camera with
specific outdoor settings.
