The SNC-Z20N incorporates a highly sensitive 1/4" CCD with Exwave HADTM technology for superb picture quality. Images are compressed using the industry standard JPEG-compression format for efficient distribution over a network. Equipped with an auto-focus 18x optical zoom lens, this camera can zoom in on small or distant objects with exceptional clarity. Frame rates of 30 fps1 at VGA resolution is just one of the many capabilities of the SNC-Z20N. Its built-in web server allows images to be viewed and controlled from a PC running a standard web browser. The SNC-Z20N also offers a variety of other sophisticated features such as Day/Night mode, Slow Shutter, and Activity Detection functions, ideal for remote monitoring operations.

The SNC-Z20N offers a Day/Night function to provide optimized sensitivity in both day and night shooting scenarios. As the scene illumination decreases and the image darkens, the infrared cut filter is automatically removed and the camera switches to B/W mode that achieving a minimum illumination of 0.01 lx (F1.4, 50 IRE, Slow shutter OFF) --a drastic improvement from 0.7 lx minimum illumination in color mode. In addition, the slow shutter mode provides a remarkable enhancement in sensitivity by allowing the charge accumulation period of the CCD to be extended to a maximum of one second.
