Product Description

The Lorex SG254 5-inch B/W 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 sequentially in full-screen with its built-in four-channel switcher. The included four cameras have built-in motion detection capabilities so you won't miss any action. Featuring two-way audio, the Lorex SG254 is a complete, self-contained observation system perfect for home or business applications.

The SG254's 5-inch black-and-white monitor is protected by a durable metal cabinet, and includes four 6-pin 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 a two-way audio capability that lets you speak to a camera location with the push of a button, as well as RCA outputs for connecting to a time-lapse VCR or DVR. The four cameras that come with the SG254 utilize 0.33-inch black-and-white CMOS (complimentary metal-oxide semiconductor) image sensors with 3.6mm fixed wide-angle lenses. Powered from the monitor via the connecting cables, these cameras can receive a usable picture in very low-light conditions with a minimum illumination of 0.1 Lux. 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 SG254's cameras come with their own 63-foot connection cables, and can operate in temperatures ranging from 14 to 122 degrees Fahrenheit.

Technical Features:

  • Camera lenses: 3.6mm fixed wide-angle
  • Image sensor: 0.33-inch B/W CMOS
  • Sensitivity: minimum illumination of 0.1 Lux
  • Operating temperature: 14 to 122 degrees Fahrenheit
  • Camera dimensions: 2.5 x 3 x 2 inches (W x D x H)
Designed primarily for indoor use, the Lorex SG254 offers you everything you need in a basic security surveillance system. Compatible with other Lorex digital video devices, the SG254 allows up to four cameras to be controlled, viewed, and recorded all by a single unit. Users should note that the CMOS 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.
