The Clover OB250 B/W Indoor Night Vision Camera with 12 LEDs is a fast and simple-to-operate outdoor video surveillance camera that has the ability to record even under no-light conditions. This camera provides high-quality images at high-resolutions, has 12 LEDs that emit an invisible light for illumination up to 30 feet away, and can be used with most TVs or VCRs to allow users to remotely monitor warehouses, construction sites, parking lots, office buildings and more. Easy to install, the OB250 is designed for primarily indoor use, but can be used in well-protected outdoor environments as well. This camera utilizes a 0.33-inch black-and-white CCD (charge-coupled device) sensor, with a resolution of 512-by-492 pixels or 380 TVL (TV lines). The OB250 includes a 3.6mm lens, and a better-than 46 dB S/N (signal to noise) ratio. The unit's exposure times range from 1/60 to 1/100,000 of a second, ensuring a high picture quality. This camera can provide a frame rate of up to 30 frames-per-second (frames per second), equivalent to a 460-NTSC analog video. Powered via a 12-volt external DC power supply (included), it can operate in temperatures from -10 to 50-degrees Celsius. Technical Features: - S/N ratio: more than 46 dB
- Frame rate: up to 30 frames per second
- Resolution: up to 512 by 492 pixels or 330 TVL
- Operating temperature: -10 to 50 degrees Celsius
- Dimensions: approximately 5 x 2 x 4.5 centimeters (W x D x H)
Overall, the Clover OB250 provides you with a reliable, easy-to-use camera that can complement most any monitoring system. Quick and easy to install, this camera comes completely assembled and ready to use, and is designed to cover areas that sometimes receive absolutely no ambient light, even up to 30 feet away. Users should note, however, that the CCD sensor may become permanently damaged if exposed to long hours of direct sunlight or halogen light. 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. About Infrared Cameras
An infrared camera uses an infrared illuminator for low-light and nighttime viewing. Typically designed with fixed focal lengths, infrared cameras provide black and white images of nighttime viewing, and many have color capability for daylight use.
