JVC VN-C655U manual Features, Operating Precautions

Features

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).

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.

DSP with a wide dynamic range

Even objects that have a large difference in bright- ness can be monitored clearly.

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).

High-speed pan/tilt table

The high-speed rotating table with a horizontal panning speed of 300û/sec. and a vertical tilting speed of 180û/sec. makes it possible to recall a preset position quickly.

Frame Rate

Up to 30 frames per second in 640 x 480 VGA resolution.

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.

Image Recording Function

Equipped with an image recording function by alarm input.

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.

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.

Operating Precautions

To save energy, turn the system power off when- ever it is not in use.

This camera cannot be used outdoors if the op- tional outdoor housing is not attached.

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.

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 0ûC to 50ûC (32ûF to 122ûF).

¥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.

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.

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.

Do not point the lens at a strong light source, for example the sun, doing so may cause the cam- era to malfunction.
