The SPECO CVC-637EX H.E.A.T. Miniature Color Bullet Camera with Built-in 3.6mm Lens is great for any outdoor applications, especially those involving discreet video surveillance. Constructed with a durable weatherproof housing, this camera’s incredibly small size allows it to be placed virtually anywhere without drawing attention to itself. Designed to provide a high-resolution picture even in low-light conditions, the SPECO CVC-637EX is a great addition to any video surveillance system, especially in round-the-clock outdoor applications requiring stealth.
This bullet camera utilizes a 0.33-inch color Sony HAD CCD (charge-coupled device) image sensor with a 3.6-millimeter fixed lens. The CVC-637EX has an extremely high resolution of 470 horizontal TVL (TV lines), and achieves a S/N (signal-to-noise) ratio of 50 dB or better. Very sensitive to light, this unit can receive a clear and usable picture with a minimum illumination of 0.03 Lux. The SPECO CVC-637EX includes a standard BNC (Bayonet Neill-Concelman) video output, runs on 12-volts DC power, and can operate in temperatures ranging from -20 to 122 degrees Fahrenheit. The CVC-637EX 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 50 dB
- Minimum illumination: 0.03 Lux
- Horizontal resolution: 470 TVL
- Operating temperatures: -20 to 122 degrees F
- Dimensions: 1 x 2.6 inches (diameter x depth)
The SPECO CVC-637EX 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.
