This bullet camera utilizes a 0.25-inch color CCD (charge-coupled device) image sensor with a 3.6-millimeter fixed lens, and provides 510-by-492 effective pixels. The CVC-627 has a high resolution of 420 horizontal TVL (TV lines), and achieves a S/N (signal-to-noise) ratio of 48 dB or better. Already extremely sensitive to light with a minimum illumination of 0.01 Lux to infinity, this camera has 12 built-in IR (InfraRed) LEDs (light emitting diodes) that allow it to receive a picture in total darkness (0 Lux) up to 45 feet away, as well as a CDS sensor that turns the IR illuminators on automatically when it gets dark. The SPECO CVC-627 operates on the NTSC TV scanning system, and includes a standard BNC (Bayonet Neill-Concelman) video output. This unit runs on 12-volts DC power and can operate in temperatures ranging from -14 to 120 degrees Fahrenheit. The CVC-627 comes complete with automatic gain control and back-light compensation, and a built-in automatic electronic shutter with speeds ranging from 1/60 to 1/100,000 of a second.

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.
