Product Description


The Lorex SG21284-A 21-inch 2-page/8-channel 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 eight camera locations in real-time sequentially in full-screen, or simultaneously in quad or PIP (picture-in-picture) modes. The included eight cameras have a built-in motion-sensing function so you won't miss any action. Featuring two-way audio, remote control, and other features the Lorex SG21284A is a complete, self-contained observation system perfect for everything from the home or business applications, to professional security installations.

The SG21284A's 21-inch color picture-tube monitor can be operated via its built-in main panel or via an included remote control. Built inside a durable metal cabinet housing, this monitor includes eight DIN/BNC (Bayonet Neill-Concelman, RF-type) composite video inputs, and eight RCA audio inputs. Also included are eight alarm inputs with two alarm outputs for connecting external alarm devices. The SG21284A monitor features on-screen display of date/time/camera, a stand-by switch that allows recording to occur while monitor is off, video-loss detection warning, and two-way audio capability that lets you speak to a camera location with the push of a button. This unit also features selectable still-frame in quad or full-screen, as well as a POP (picture-out-of-picture) display mode. Multi-voltage compatible, the SG21284A's monitor runs on 100 to 240-volts of power, achieves an extremely high horizontal resolution of 800 TVL (TV lines) at up to 30 fps (frames-per-second), and has an operating temperature of 32 to 104 degrees Fahrenheit.

The cameras that come with the SG21284A utilize 0.25-inch color CCD (charge-coupled device) image sensors with a 3.6mm fixed lenses. Powered from the monitor via their connecting cables, these cameras achieve a horizontal resolution of 330 TVL and are constructed of durable white ABS (Acrylonitrile Butadiene Styrene) plastic. These units feature automatic electronic shutters with speeds ranging from 1/60 to 1/100,000 of a second, and PIR (passive InfraRed) motion sensors that alert you of camera activity. The SG21284A's cameras come with their own 63-foot connection cable, allowing you to install it virtually anywhere, and can operate in temperatures ranging from -14 to 122 degrees Fahrenheit.

  • Resolution: monitor 800 TVL up to 30 fps, camera 330 TVL
  • Operating temperature: -14 to 122 degrees Fahrenheit for camera; 32 to 104 degrees Fahrenheit for monitor
  • Monitor dimensions: 19.5 x 18 x 18 inches (W x D x H)
  • Camera dimensions: 3 x 3.6 x 3.5 inches (W x D x H)
Designed primarily for indoor use, the Lorex SG21284A offers you everything you need in a security surveillance system. Though only four cameras are included, the SG21284A allows up to eight 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 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.
