Product Description

The Sylvania SY21424-A 21-inch Color Quad Observation System with 4 Cameras provides convenience, versatility, and quality in a robust and complete system. This system allows you to view up to four camera locations in real-time sequentially in full-screen, or simultaneously in quad or PIP (picture-in-picture) modes. The included four cameras have built-in microphones and speakers allowing audio communication between the monitor and any camera location. Rich in features, the Sylvania SY21424-A is a complete, self-contained observation system perfect for everything from the home or business applications, to professional security installations.

The SY20CSY21424144-A's 21-inch color picture-tube monitor can be operated via its built-in main panel or via an included remote control. Protected by a durable metal cabinet housing, this monitor includes four DIN/BNC (Bayonet Neill-Concelman) composite video inputs and four RCA audio inputs, as well as four alarm inputs and two alarm outputs for connecting external devices. The SY21424-A monitor displays date/time/camera and features single or dual PIP viewing options, a video loss-detection warning, and selectable still-frame in quad or full-screen display modes. Multi-voltage compatible, the SY21424-A's monitor runs on 100 to 240-volts of AC power, achieves a horizontal resolution of 450 TVL (TV lines) at up to 30 fps (frames-per-second), and has an operating temperature of 32 to 104 degrees Fahrenheit.

The four cameras that come with the SY21424-A utilize 0.25-inch color CCD (charge-coupled device) image sensors with 3.6mm fixed lenses. Powered from the monitor via their connecting cables, these cameras achieve a horizontal resolution of 330 TVL 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 SY21424-A's cameras come with their own 63-foot connection cable , and can operate in temperatures ranging from 14 to 122 degrees Fahrenheit.

  • 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
  • Monitor dimensions: 19.5 x 18 x 18 inches (W x D x H)
  • Camera dimensions: 2.5 x 3 x 2 inches (W x D x H)
Designed primarily for indoor use, the Sylvania SY21424-A offers you everything you need in a security surveillance system. Perfect for small- to medium-sized installations, when used with a Sylvania time-lapse VCR or DVR the SY21424-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.
