Product Description


The Lorex SG4241-A 14-inch B/W Quad Observation System with 1 Camera provides convenience, versatility, and quality in a robust and complete system. This system allows you to view up to four camera locations sequentially in full-screen mode. The included camera has a built-in motion detection capabilities so you won't miss any action. Featuring two-way audio, remote control, and other features, the Lorex SG4241-A is a complete, self-contained observation system perfect for everything from the home or business applications, to professional security installations.

The SG4241-A's 14-inch black-and-white monitor can be operated via its built-in main panel or via an included remote control. Protected by a durable metal cabinet, this monitor includes four DIN/BNC (Bayonet Neill-Concelman) video inputs, and four RCA audio inputs. Also included are four alarm inputs with two alarm outputs for connecting external alarm devices. This monitor features on-screen display of date/time/camera, selectable and sequential PIP (picture-in-picture) viewing, a 2x zoom function, and two-way audio capability that lets you speak to a camera location with the push of a button. Multi-voltage compatible, the SG4241-A's monitor runs on 100 to 240-volts of power, achieves a horizontal resolution of 450 TVL (TV lines) at center, and has an operating temperature of 32 to 104 degrees Fahrenheit.

The camera that comes with the SG4241-A utilizes a 0.33-inch black-and-white CCD (charge-coupled device) image sensor with a 3.6mm fixed lens. Powered from the monitor via the connecting cable, this camera achieves a horizontal resolution of 380 TVL with 510 by 492 active picture elements. Constructed of durable ABS (Acrylonitrile Butadiene Styrene) plastic, this camera can receive a usable picture in very low-light conditions with a minimum illumination of 0.1 Lux. This unit also features a PIR (passive InfraRed) motion sensor that alerts you of camera activity. The SG4241-A's camera comes with its own 63-foot connection cable, and can operate in temperatures ranging from -14 to 122 degrees Fahrenheit.

  • Monitor dimensions: 12.7 x 12.5 x 12.5 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 Lorex SG4241-A offers you everything you need in a security surveillance system. Though only one camera is included, the SG4241-A allows up to four cameras to be controlled, viewed, and recorded all by a single unit. Users should note that the CCD image sensor in the camera 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 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.
