This camera utilizes a 0.33-inch color CCD (charge-coupled device) sensor, with a resolution of 512-by-492 pixels or 330 TVL (TV lines). The OC225 includes a 4.3-millimeter lens, has a usable illumination down to two Lux, 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:

• Sensitivity: down to 2 Lux
• 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 4 x 9 x 4 centimeters (W x D x H)

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 Surveillance Camera Housings
Most video surveillance systems can be deployed for outside use when a proper camera housing is used. Key features for housings are a blower/fan to keep the camera cool in the summer, and a heater for the cold-weather months and to keep the glass from fogging up. Most housings can accept many types of security cameras. An outdoor dome housing is used for external mounting when tamper resistance or pan/tilt functionality is desired.
