Characteristics

High-speed Rotating Table
High-speed rotating table with a horizontal
panning speed of 180˚/sec and vertical tilting
speed of 120˚/sec makes it possible to recall
a preset position quickly.
Optical Zoom
Closer surveillance is made possible using
the 12x optical zoom lens.
Day/Night Surveillance
When the light is low, the camera is able to
switch automatically to the high-sensitive
(Black & White) mode by turning ON/OFF the
IR filter.
It also suppor ts infrared illuminators
(wavelength of 850 nm to 880 nm).
Employment of a highly-sensitive CCD
and bright zoom lens
Employment of a highly-sensitive CCD and
bright zoom lens with a maximum aperture
ratio of F1.6 (at the Wide end) produces a
highly sensitive color mode of 3.6 lx (AGC:
20 dB, 50%).

Operating Precautions

To save energy, turn off the power supply of
the system when not in use.
This camera is intended for indoor use. It
cannot be used outdoors.
This camera has been designed for suspension
from ceilings. Fixing it to the ground surface or
at an angle may cause malfunction or shorten
the product's service life.
Do not install or use the camera in the
following locations.
• Places exposed to rain or water
• Places containing vapor or oil soot, such
as kitchens
• Places exceeding the operating ambient
temperature range (0˚ to 40˚)
• Places where corrosive gases are
generated
• Places nearby radiation or X-rays as well
as sources of strong radio waves or
magnetism
• Places subject to vibration
• Places with excessive dust
Insufficient ventilation may cause the camera
to malfunction. Be careful not to block
ventilation around the camera.

at one time without lowering the frame rate.
Built-in CF (Compact Flash) Slot
Interface with alarms and enables storage of
a recording file in the CF card. Please
purchase the CF card separately.
Private Mask Feature

portion of the shooting area if it is to be
hidden.

Built-in Web Server
Enables browsing using the Internet Explorer.
(top panel facing ceiling and side panel). Do
not install at a location that may trap heat,
such as near the walls.
Do not install at a location that may expose the
camera directly to cool air, such as nearby the
air outlet of air conditioners. This may cause
moisture to condense within the dome cover.
Dew condensation may occur when there is
a drastic change in the ambient temperature
of the camera, hence causing a malfunction.
When the camera is installed at such
locations, turn on the power after allowing it
to dry for a few hours.
Do not point the camera lens at a strong light
source such as the sun. Doing so may cause
the camera to malfunction.
This camera contains a built-in AGC circuit.
As a result, gain increases at dark places
and screen may appear grainy. This is not a
malfunction.
When an equipment that generates a strong
magnetic field, such as transceivers, is used
near this camera with the AGC turned on, beat
noises may appear in the image. When using
a transceiver, therefore, place it at least 3 m
away from this camera.
