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%).

Frame Rate

Supports a maximum frame rate of 30 fps

when resolution is 640 x 480 in the JPEG
compression format.

Supports Multicast

Support for multicast enables sending of an

image data to multiple PCs on the network
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

This feature enables setting to mask a certain

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

Motion Detection Feature

Enables output of alarm upon detecting

motion of images within a specified area.

Built-in Web Server

Enables browsing using the Internet Explorer.

Operating Precautions

Ⅵ To save energy, turn off the power supply of

the system when not in use.

Ⅵ This camera is intended for indoor use. It

cannot be used outdoors.

Ⅵ 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.

Ⅵ 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

Ⅵ Insufficient ventilation may cause the camera

to malfunction. Be careful not to block
ventilation around the camera.
This camera radiates heat from its surfaces

(top panel facing ceiling and side panel). Do
not install at a location that may trap heat,
such as near the walls.

Ⅵ 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.

Ⅵ 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.

Ⅵ Do not point the camera lens at a strong light

source such as the sun. Doing so may cause
the camera to malfunction.

Ⅵ 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.

Ⅵ 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.
