This miniature camera utilizes a 0.33-inch CCD (charge-coupled device) image sensor with a 3.6-millimeter conical pinhole lens, and provides 512-by-492 effective pixels. The CVC-57PH/HR has a high horizontal resolution of 400 TVL (TV lines), works well in low-light conditions with a minimum illumination of 0.5 Lux, and achieves a S/N (signal-to-noise) ratio of 46 dB or better. The SPECO CVC-57PH/HR operates on the EIA (Electronics Industries Association) scanning system, and includes a standard RCA for video output that allows it to connect to most any TV or VCR. This unit runs on 12-volts DC power, and can operate in temperatures ranging from 14 to 122 degrees Fahrenheit. The CVC-57PH/HR comes complete with a built-in automatic electronic shutter with speeds ranging from 1/50 to 1/10,000 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.
