The Sony SNC-Z20N Color Network Camera is a digital network camera that distributes live images or video over an intranet or the Internet via a built-in web-server. The Sony SNC-Z20N allows high-quality remote surveillance from any browser on the network, and provides full Web-based control of its various management and configuration functions. Connecting via 10/100 Base T/TX Ethernet for both networking and power, the SNC-Z20N achieves up to 30 fps (frames per second).
This camera utilizes a 0.25-inch color Exwave HAD CCD (charge-coupled device) image sensor and provides up to 640-by-480 effective pixels at high resolutions. With an extraordinary 18x optical and 12x digital zoom that allows you to clearly pick out even the most distant objects, the Sony SNC-Z20N features a PCMCIA slot for 802.11b wireless networking or flash memory, good nighttime sensitivity with a minimum illumination of 0.7 Lux, and a clever E-flip function for correct image presentation in ceiling-mount applications.

About Surveillance Camera Technical Features
Lux rating is the measurement used to indicate how sensitive a camera is to light, and stands for the level of light reflected off a piece of paper by a candle from one meter away. Thus a sensitivity of three Lux would mean a camera could generate an acceptable picture of a piece-of-paper-sized object that was illuminated by the equivalent of three candles from one meter away. The lower the Lux level, the better the camera's ability to work in low-light conditions. The camera's resolution should be greater than or equal to the resolution supported by the system's recorder or monitor. The S/N, or signal to noise ratio, is an important measure of a camera's quality. A poor camera, low-light conditions or poor wiring causes "noise" which consumes processing power and disk space. A camera with a wide dynamic range is ideal, especially for recording areas in which both indoor and outdoor light are present. CCD (charge-coupled device) sensors provide high-quality images that are less susceptible to noise. CMOS (complimentary metal-oxide semiconductor) sensors offer less image quality, but are usually more cost-effective and energy efficient.
About IP Cameras
An IP camera can be used to project images and video directly through a computer's Web browser for remote monitoring. An IP camera, unlike a web cam, contains the IP and Web page within it and can often be added to a network without additional configuration or software. Combined with a network video recorder, an IP camera can be used to construct a reliable video surveillance system.
About Pan/Tilt Cameras
A Pan/Tilt Camera has the ability to pan ("move" horizontally), or tilt ("move" vertically). IP cameras often have pan/tilt capability. A pan/tilt camera is ideal for monitoring of situations that need a continual real-time adjustment of the views.
