Features
Ⅵ High-sensitivity CCD and bright zoom lens
The CCD features an improved sensitivity and the
zoom lens has a large aperture ratio of f1.6 (at
WIDE end). These features provide the camera
with a high sensitivity of 2.0 lx in the color mode
(50% output, AGC 20 dB).
Ⅵ Optical + Electronic zooming
The 25X optical zoom lens and 10X electronic
zoom circuitry allows the camera to be used even
in surveillance situations in which the object is very
small.
Ⅵ DSP with a wide dynamic range
Even objects that have a large difference in bright-
ness can be monitored clearly.
Ⅵ Day/Night surveillance
When the light is low, the camera pictures can be
switched automatically to black and white pictures.
The camera is also compatible with IR illumination
(wavelength 850 nm to 880 nm).
Ⅵ High-speed pan/tilt table
The high-speed rotating table with a horizontal
panning speed of 300˚/sec. and a vertical tilting
speed of 180˚/sec. makes it possible to recall a
preset position quickly.
Ⅵ Frame Rate
Up to 30 frames per second in 640 x 480 VGA
resolution.
Ⅵ Supports Multicast
With Multicast, the same image data can be sent
at one time to multiple computers on the network
without decreasing the frame rate.
Ⅵ Image Recording Function
Equipped with an image recording function by
alarm input.
Ⅵ Conventional surveillance camera peripheral
can be used
VN-C655 has a design similar to other CCTV moni-
toring cameras, allowing peripheral equipment for
such cameras to be also used for VN-C655.
Ⅵ Private masking facility
When the camera target area contains an area
that is required to be hidden the camera can be
set accordingly in order to mask it.
Ⅵ To save energy, turn the system power off when-
ever it is not in use.
Ⅵ This camera cannot be used outdoors if the op-
tional outdoor housing is not attached.
Ⅵ This camera has been designed to be hung from
a ceiling with its base uppermost.
Do not install it in an upside down position on
surface or at an angle, as this may cause mal-
function or a noticeable shortening of its ser-
vice life.
Ⅵ Do not install or use the camera in the following
locations.
• In a place exposed to rain or water.
• In a place containing vapor or oil soot, for ex-
ample in a kitchen.
• In a place outside the operating temperature
range 0˚C to 50˚C (32˚F to 122˚F).
• Near a source of strong radio waves or mag-
netism, radiation or X-rays.
• In a place where corrosive gasses are gener-
ated.
• In a place subject to vibrations.
• In a place with excessive dust.
Ⅵ Insufficient ventilation of the camera may cause
a malfunction. Be careful not to block ventila-
tion to the camera. This unit radiates heat from
the panel surfaces (top panel and side panels).
Do not install it in a place where a heat pool
may form, such as near a wall.
Ⅵ Do not install the camera in a place exposed to
cold air, for example near to the air outlet of an
air onditioner. Otherwise, moisture may become
condensed inside the dome cover.
Ⅵ Do not point the lens at a strong light source, for
example the sun, doing so may cause the cam-
era to malfunction.
