| JVC Launches the VN-V686U PTZ Network Dome Camera JVC introduces the VN-V686U Pan/Tilt/Zoom (PTZ) network dome camera, following the recent release of VN-V686WPU outdoor vandal and weather resistant model. JVC product advantages stem from the core in house technical disciplines in mechanical engineering, image processing and software development which have led to the JVC's direct drive pan/tilt motor silent operation with incredible accuracy to 0.03°. Operation speed can be extremely fast, or excruciatingly slow, meaning finding and tracking objects is much easier. Additionally, the VN-V686U precisely maintains operator assigned preset camera positions even after frequent panning and tilting — especially important with its high zoom ratio. The VN-V686U features 36x optical zoom lens with a focal length of 3.4mm to 122mm, for crystal clear long-range images. The optical zoom capability is complemented with an image stabilization system based on an internal gyro instead of less reliable digital image processing. A powerful ¼-inch CCD with 380,000 pixels and full motion dual stream codec delivers both MJPEG and MPEG4 streams simultaneously. MPEG4 images are ideal for monitoring because they require less bandwidth and MJPEG images are recorded for forensic purposes. True day/night operation is achieved with the IR Cut Filter, delivering images in light levels as low as 0.04 lux. Installation and maintenance are also incredibly easy with the unique mechanical design from JVC, which separates the network intelligence hardware from the camera hardware with a hot swap removable camera head. In addition, a variety of installation options are available from JVC for wall mount, recessed ceiling mount or pendant mount using optional accessories. The camera features a motion detection and tracking function that outputs an alarm whenever movement is detected within a pre-specified area of the image. The onboard tracking function may be turned on by the operator to automatically lock on to a moving object or person. write your comments about the article :: © 2008 Computing News :: home page |
