Homeland Security 810 Day and Night Color Security Camera, Silver

The 00810's utilizes a 0.25-inch color CCD (charge-coupled device) image sensor, and achieves a horizontal resolution of 380 TVL (TV lines). Already excellent in low-light conditions with a minimum illumination of one Lux to infinity, this unit includes 12 IR (infrared) LEDs (light-emitting diode) that allow it to see in no-light (0 Lux) conditions within a limited distance. Ideal for outdoor use with a weather-resistant housing, the 00810 features automatic infrared trigger-on under low illumination. Including a 60-foot connecting cable that allows placement flexibility, the easy-to-install 00810 connects to most any standard TV, VCR or monitor. Users should note that the CCD image sensor in this camera 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 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 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.
