Product Description

The Philips VS23645T B/W Quad Observation System offers a cost-effective solution for basic surveillance needs. This system allows you to view up to four camera locations simultaneously in real-time quad mode. The included camera incorporates a built-in motion microphone and standard alarm input-screw connector for use with external sensors. Featuring time and date display, patented EventReplay technology and other functionality, the VS23645T is a complete, self-contained observation system perfect for your home or small- to medium-sized business installations.

The VS23645T's 11-inch black-and-white monitor is operated from its built-in main panel, and includes four video inputs with four RCA audio inputs. Also included are a slave-monitor output, one-way (two-way prepared) audio input/output, and an alarm output for connecting to external devices such as a door-strike. This monitor features on-screen display of date and time, EventReplay that digitally stores several seconds of video before and after a triggered event, and a power-save feature whereby the monitor automatically turns on from power-save mode if an alarm or other device is triggered. Multi-voltage compatible, the VS23645T's monitor runs on 100 to 240-volts of AC power, achieves a horizontal resolution of 500 TVL (TV lines), and has an operating temperature of 50 to 114 degrees Fahrenheit.

The camera that comes with the Philips VS23645T utilizes a 0.33-inch black-and-white CCD (charge-coupled device) image sensor with a four-millimeter CS-mount fixed lens. Powered from the monitor via the system cable through a RJ11E connector, this camera achieves a horizontal resolution of 380 TVL with 512 by 492 active picture elements. This camera includes a built-in Electret microphone, can receive a usable picture in very low-light conditions with a minimum illumination of 0.1 Lux, and achieves a S/N (signal-to-noise) ratio of 48 dB or better. The VS23645T's camera comes with its own 75-foot connection cable, and can operate in temperatures ranging from -4 to 114 degrees Fahrenheit.

Technical Features:

  • Camera lenses: 4mm CS-mount fixed
  • Image sensor: 0.33-inch B/W CCD
  • Sensitivity: minimum illumination of 0.1 Lux
  • Resolution: monitor 500 TVL, camera 380 TVL
  • Operating temperature: -4 to 114 degrees Fahrenheit for camera; 50 - 114 degrees Fahrenheit for monitor
  • Monitor dimensions: 12.6 x 12.5 x 12.5 inches (W x D x H)
  • Camera dimensions: 2.8 x 2.5 x 2.8 inches (W x D x H)
Designed primarily for indoor use, the Philips VS23645T offers you everything you need in a security surveillance system. Though only one camera is included, the VS23645T allows up to four cameras to be controlled, viewed, and, with an easily connected VCR or DVR, 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.
