The Elmo HC7501 Color CCD Camera with Frame Accumulation is designed to emulate the performance of a three-CCD camera with a single CCD, making it ideal for remote monitoring applications at significant cost savings to you. With controls that are easily accessible by means of an on-screen menu and a frame accumulation feature that allows low-light image captures, the Elmo HC7501 is perfect for a wide range of monitoring situations such as those in industrial, medical, and scientific applications. This OEM (original equipment manufacturer) high-resolution camera utilizes a 0.5-inch interline-transfer color CCD (charge-coupled device) sensor, with 768-by-494 effective pixels at a horizontal resolution of 480 TVL (TV lines). In standard mode, this camera has a minimum illumination of 1.4 Lux, but features a frame-accumulation mode for extremely low-light conditions that lets the camera receive a usable image down to 0.02 Lux. Operating in NTSC format, this unit achieves a S/N (signal-to-noise) ratio of 50 dB or better. The Elmo HC7501 uses advanced digital signal processing and includes both a standard BNC (Bayonet Neill-Concelman, RF-type) 12-pin VBS (video burst sync) connector and a Y/C (luminance/chrominance or S-Video) 12-pin connector for video out. This unit comes complete with features such as AGC (automatic gain control), automatic or manual white balance, and backlight compensation with selectable zones. Powered via 12-volt DC (either four-pin or 12-pin), the HC7501 can mount both CS and C type lenses.
Technical Features:
- S/N ratio: 50 dB with AGC off
- Sensitivity: 1.4 Lux standard, 0.02 Lux in Frame Accumulation mode
- Effective pixels: 768 by 494 pixels
- Horizontal resolution: 480 TVL in NTSC
- Dimensions: approximately 6 x 14 x 6 centimeters (W x D x H)
The Elmo HC7501 surveillance camera is a reliable, economical and high-quality solution for demanding remote monitoring applications. Designed for primarily indoor use, this unit requires a housing to be used in anything but well-protected outdoor environments. 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.
