This day-and-night bullet camera utilizes a 0.33-inch color Sony Exview HAD CCD (charge-coupled device) image sensor with a 12-millimeter DC auto-iris lens, and provides 768 by 492 effective pixels. The CVC-980IR has an extraordinarily high resolution of 570 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 0.001 Lux to infinity, this camera has eight built-in super-range IR (InfraRed) LEDs (light emitting diodes) that allow it to receive a picture in total darkness (0 Lux) up to 150-feet. Additionally, the CVC-980IR has a built-in CDS sensor that turns the IR illuminators on automatically when it gets dark. The SPECO CVC-980IR runs on a regulated 12-volts DC power supply, and can operate in temperatures ranging from -20 to 122 degrees Fahrenheit. The CVC-980IR comes complete with 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.
