Description of Jwin JV-TV2040 5.5-inch B/W Security Monitor with Infrared Camera

The JV-TV2040 has a low energy consumption and excellent stabilization, and features a two-channel A/V input (for use with two cameras) and a single-channel A/V simultaneous output. The black-and-white JV-AC51 camera delivers a decent resolution of 380 horizontal TVL (TV lines), and achieves a better than 48 dB S/N (signal-to-noise) ratio. Already highly sensitive to light with a minimum illumination of 0.5 Lux when viewing in regular mode, the JV-AC51 can receive a picture under no-light conditions thanks to six IR (infrared) LEDs (light-emitting diodes). The JV-TV2040 also features auto-switching between camera one and camera two, and two- to 20-seconds auto-switching delay times that can be set by the user. Compatible with the EIA (Electronics Industries Association) TV system, the Jwin JV-TV2040 black-and-white monitor runs on 15-volt DC power via an included AC/DC adapter, and has an operating temperature of 14 to 122-degrees Fahrenheit.

Technical Features:

• Signal compatibility: EIA TV system
• Light sensitivity: 0.5 Lux to infinity, 0 Lux in via IR LEDs
• Horizontal resolution: 380 TVL
• S/N ratio: better than 48 dB
• Operating temperature: 14 to 122-degrees Fahrenheit
• Monitor dimensions: 8.19 x 7.56 x 6.02 inches (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.
