INSTALLATION
This camera unit is designed to be hanged from a ceiling. Other installation method may cause abnormal operation.
Refer to the mounting bracket (sold separately) etc. instruction manual.
Location
•
Ceiling structure
The ceiling must be strong enough to support the weight of
the camera and its accessories. Do not mount to a surface
that may vibrate when the camera is operating.
•
Protect from water leaks
This unit is to be used indoors exclusively. Do not install it
where it may be exposed to water leaking from pipes, rain,
etc.
•
Protect from vibrations
Never mount to a ceiling surface that may be subjected to
vibration or shocks.
•
Protect from damages due to humidity
The camera must be installed at a minimum distance of 1.5 m
from the air outlet of an air conditioning. If it cannot be helped,
and the camera is installed close to an air conditioning, make
sure the air flow is not directed towards the camera. If
necessary, install a cover or other protection to deflect the air.
If cold air is directed onto the camera, that may fog the lens
and the image may be blurred. Also, condensation may form
on metal parts inside the unit and that may cause corrosion
and other damages.
•
Maintaining safety
This camera unit is designed to be used hanging from a
ceiling. It is therefore very important to ensure safety by
carefully reading the mounting bracket instruction manual and
making sure it is secure and that there is no risk of the
bracket falling down.
Filming results
•
Ghosting
If a light source (such as a spotlight, etc.) is directed to the
camera lens, even if it is not in the filming range, there may
be ghosting (apparition of a secondary image).
This can be corrected by changing the light source direction
or position, or the camera location.
•
Reproduction of colours
If the lighting in the area covered by the camera is of a single
type (all fluorescent or all incandescent), the colours can be
reproduced accurately. However, if the lighting type is mixed
(fluorescent and incandescent), the colours may not be
reproduced properly.
•
Subject illumination
This camera can accommodate a wide range of lighting
intensities. However, the minimum lighting intensity for the
main subject is 20 lux with the zoom in wide angle position
and 40 lux in telephoto position. This level should be
maintained with additional lighting, in particular at night or in a
dark environment.
