One of the main benefits of a plasma screen is the vivid and brilliant color display of over 16 million colors. Additionally, the 6842PF boasts extremely wide viewing angles (compared to most LCD screens), and easy placement due to its slim profile of less than 5 inches of depth. And like all plasma displays, the 6842PF is immune to the distortion and negative color balances one may encounter when using a conventional CRT television near flourescent lighting or speaker systems.

25-inch color CCD (charge-coupled device) image sensors with 3. 6mm fixed wide-angle lenses. Powered from the monitor via their connecting cables, these cameras achieve a horizontal resolution of 330 TVL with 510 x 492 effective pixels, and can receive a usable picture at a minimum illumination level of 0. 5 Lux for low light-condition viewing. Constructed of durable white ABS (Acrylonitrile Butadiene Styrene) plastic, the SY20C6144-A's cameras come with their own 63-foot connection cable allowing you to install them virtually anywhere, and can operate in temperatures ranging from 14 to 122 degrees Fahrenheit. The Sylvania SY20C6144-A's built-in time-lapse VCR utilizes a dual azimuth four-head rotating helical scanning system that provides a resolution of 250 horizontal TVL in color, and 300 TVL in black-and-white recording. This unit operates on the NTSC color TV system, includes four selectable audio recording speeds, 14 selectable video recording speeds, and features a long-life ball-bearing Capstan motor that provides 250 to 800-percent longer life than standard time-lapse VCR's. The SY20C6144-A uses a standard BNC (Bayonet Neill-Concelman) video input/output connection, a standard RCA audio input/output connection, and includes an alarm input/output connection as well. Technical Features: Camera lenses: 3. 6mm fixed wide-angle Sensitivity: minimum illumination of 0. 5 Lux Image sensor: 0. 25-inch color CCD Resolution: monitor 380 TVL up to 30 fps, camera 330 TVL Operating temperature: 14 to 122 degrees Fahrenheit for camera; 41 to 104 degrees Fahrenheit for monitor VCR recording space: 40-hours real-time, 1,280 hours total Camera dimensions: 2. 25 x 2. 5 x 3. 33 inches (W x D x H) Designed primarily for indoor use, the Sylvania SY20C6144-A offers you everything you need in a security surveillance system. Perfect for small- to medium-sized installations, the SY20C6144-A allows up to four cameras to be controlled, viewed, and recorded all by a single unit. Users should note that the CCD image sensors in the cameras may become permanently damaged if exposed to long hours of direct sunlight or halogen light, so the cameras 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.
