This camera utilizes a 0.33-inch black-and-white CCD (charge-coupled device) sensor, with a resolution of 512-by-492 pixels or 380 TVL (TV lines). The CM600W includes a 3.6mm lens, and has a usable minimum illumination down to 0.1 Lux. The unit's built-in electronic auto iris control, built-in automatic backlight compensation, low-illumination function, and exposure times ranging from 1/60 to 1/100,000 of a second, ensuring a high picture quality with user-definable parameters. This camera can provide a frame rate of up to 30 frames-per-second (frames per second), equivalent to a 460-NTSC analog video. Powered via a 12-volt external DC power supply (included), it can operate in temperatures from -10 to 50-degrees Celsius.

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.
