Jwin JV-TV2040 5.5-inch B/W Security Monitor with Infrared Camera description
The Jwin JV-TV2040 5.5-inch B/W Security Monitor with Infrared Camera is a simple and reliable solution for most basic remote monitoring needs. The easy-to-install Jwin JV-TV2040 monitor comes complete with a Jwin JV-AC51 IR (infrared) camera with a 60-foot cable so you can install it almost anywhere. This system allows for both day and night viewing and includes A/V (audio/video) outputs for recording, making it perfect when low-cost 24-hour surveillance is required, and for monitoring rooms, entrances, or other areas in your home or business. 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.

Designed primarily for indoor use, the Jwin JV-TV2040 two-camera monitor deserves serious consideration as one of the most care-free and user-friendly monitoring solutions for small to medium scale surveillance applications. The Jwin JV-AC51 camera that comes with this system is easy to use and install, and includes a built-in microphone. User's should note that the image 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. |
