This camera utilizes a 0.25-inch color interline-transfer CCD (charge-coupled device) image sensor, with up to 512 by 492 effective picture elements. Built with a 3.6-millimeter fixed lens, the CVC-6993P has a good resolution of 350 horizontal TVL (TV lines). For use during the day this camera has a minimum illumination of one Lux in color, but at night this camera automatically switches to black-and-white and uses its 12 LED (light-emitting diode) emitters to allow a vision range of up to 30 feet in 0.1 Lux lighting. The IP67 (Ingress Protection) rating means this unit has a protection level of six against solid-body ingress, and a protection level of seven against the ingress of water. Six is the top protection level against solid bodies, meaning the CVC-6993P is certified dust proof. Seven is the second highest protection level against water, meaning this unit will protect your camera against the effects of temporary immersion between 15-centimeters and one-meter for up to at least 30 minutes. The CVC-6993P features a built-in electronic auto-iris for automatic light compensation, and has a shutter speed ranging from 1/60 to 1/100,000 of a second. This unit runs on 12-volt DC power, and has an operating temperature of five- to 131-degrees Fahrenheit.

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.
