The SPECO CVC-638/170 Ultra Wide-angle Waterproof Color Bullet Camera is great for any outdoor application. Constructed with a durable waterproof housing, this camera's compact design allows it to be placed virtually anywhere. Designed to provide a high-resolution picture with a very wide viewing angle, the SPECO CVC-638/170 is a great addition to any video surveillance system, especially in applications subject to inclement weather conditions.
This bullet camera utilizes a 0.33-inch color CCD (charge-coupled device) image sensor with a 2.2-millimeter ultra wide-angle lens that gives the camera a 170-degree field of view. With 512-by-492 effective pixels, the CVC-638/170 has a high resolution of 380 horizontal TVL (TV lines), and achieves a S/N (signal-to-noise) ratio of 48 dB or better. Fairly sensitive to light, this camera can receive a usable picture with a minimum illumination of one Lux. The SPECO CVC-638/170 operates on the NTSC TV scanning system, and includes a standard BNC (Bayonet Neill-Concelman) composite video output. This unit runs on a regulated 12-volt DC power supply, and can operate in temperatures ranging from 14 to 122 degrees Fahrenheit. The CVC-638/170 comes complete with a built-in automatic electronic shutter with speeds ranging from 1/60 to 1/100,000 of a second.
Technical Features: S/N ratio: better than 48 dB Sensitivity: minimum illumination of 1 Lux Effective pixels: 512 by 492 pixels Horizontal resolution: 380 TVL Operating temperatures: 14 to 122 degrees Fahrenheit Dimensions: 1.5 x 3.5 inches (diameter x depth) The SPECO CVC-638/170 camera provides you with a high-quality color picture from a camera that can go virtually anywhere, and deserves serious consideration as an addition to any severe-weather security system. Users should note that the CCD sensor may become permanently damaged if exposed to long hours of direct sunlight or halogen light, so the camera should not be mounted or pointed directly at the sun or other bright-light sources.
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.
