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.

The progressive scan technology is particularly advantageous as it reduces motion blur, making it suitable for capturing fast-moving subjects. Furthermore, the camera offers a frame rate of up to 30 frames per second, ensuring real-time monitoring without noticeable latency.

The VN-C655U is also designed with versatility in mind. It supports both indoor and outdoor usage, thanks to its robust construction and weather-resistant features. This adaptability ensures that the camera can perform effectively in different environmental conditions. Additionally, the camera is equipped with a 10x optical zoom lens, which allows for detailed close-ups without losing image quality. With a wide field of view, the VN-C655U can cover expansive areas and is perfect for monitoring large facilities.

Connectivity is another key aspect of the VN-C655U. It supports Power over Ethernet (PoE), which allows for simplified installation by streamlining cabling requirements. Users can also access the camera remotely via a web interface, making it easy to configure settings and monitor footage from anywhere using an internet connection. This feature is integral for security personnel needing real-time oversight and control over surveillance operations.

The JVC VN-C655U incorporates advanced image processing technologies, including wide dynamic range (WDR) to handle challenging lighting conditions. This capability ensures clear images, even in high-contrast environments where shadows and bright light coexist. Additionally, the camera supports motion detection, generating alerts and notifications when activity is detected within designated areas, enhancing security and response times.

Overall, the JVC VN-C655U is a feature-rich network camera tailored for modern surveillance needs. With its excellent image quality, versatile design, advanced connectivity, and intelligent monitoring capabilities, it serves as a reliable option for anyone seeking to enhance the security of their premises. Whether for business or public safety applications, the VN-C655U proves to be a valuable asset that combines performance with flexibility.
