This day-and-night CCTV camera utilizes a 0.33-inch interline-transfer CCD (charge-coupled device) image sensor with a standard CS-mount lens that employs 510 by 492 effective pixels. The IK-6200A provides a good resolution of 350 horizontal TVL (TV lines), and has a great S/N (signal-to-noise) ratio of 50 dB or better. This camera features backlight compensation, automatic electronic shutter and gain controls, and features a sensitivity to light that allows a usable picture at a minimum illumination of 0.2 Lux. The Toshiba IK-6200A operates on the NTSC video format, is dual-voltage compatible running on either 24-volts AC or 12-volts DC power, and can operate in temperatures ranging from 14 to 122 degrees Fahrenheit. This unit is mounted by a 0.25-inch threaded screw, holes for which are provided on both top and bottom.

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.
