Editorial Review: Product Description: Amazon.com Product Description: 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:
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. Average Rating:
 Rating: - Great wide-angle video cameraI bought this camera as a rear-view camera to aid in docking my 40-foot power boat. I selected it because it is rated for outdoor use and it provides a nearly 180 degree view (170 actually). I have been very impressed. I moored in a tight spot the first week I had the boat, with only 55 feet available to back out my slip and turn 90 degrees to exit. I was able to move within a few feet of the boats behind me with confidence, because the video image quality is excellent in daylight, and the wide ... Read More |
