Amazon.com Product ReviewThe Elmo UN411E Color CCD Ultra-micro Video Camera is compact and lightweight, and an excellent solution in many monitoring situations involving specialized circumstances. Designed to fit with a large variety of Elmo's micro and macro lenses, the Elmo UN411E's one-piece construction and high resolution make it perfect for medical and scientific applications, while its miniature size makes it ideal for covert surveillance purposes. This micro video camera utilizes a 0.33-inch color interline-transfer CCD (charge-coupled device) sensor, with 768-by-494 effective pixels at a horizontal resolution of 470 TVL (TV lines). This camera has a minimum illumination of 15 Lux, and achieves a S/N (signal-to-noise) ratio of 46 dB or better. The Elmo UN411E operates on the NTSC format and includes a VBS (video burst sync) connector, and dual function BNC (Bayonet Neill-Concelman, RF-type)-composite and Y/C (luminance/chrominance, or S-video) connection for video out. This unit comes complete with features such as AGC (automatic gain control), manual or automatic white balance, and the option of interchangeable cables ranging from two- to 30-meters in length. Powered via 12-volt DC, the UN411E can operate between -10 and 40-degrees Celsius. Technical Features: - S/N ratio: better than 46 dB
- Sensitivity: 15 Lux
- Effective pixels: 768 by 494 pixels
- Horizontal resolution: 470 TVL
- Operating temperatures: -10 and 40-degrees Celsius
- Dimensions: 1.25 cm in diameter, ranging from 4.75 to 8.25 cm in length depending on lens
The Elmo UN411E camera is a reliable and high-quality solution for a wide variety of surveillance and monitoring situations. Designed for primarily indoor use, this camera requires a CCU (computer control unit) that is included. This camera also requires an optional connecting cable, such as the EMC-02D, that is not included. User's should note that the CCD sensor 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 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. |
