The SY2500's receiver utilizes the 2.4 GHz signal system allowing reception through walls and ceilings, and has a built-in five-inch black-and-white monitor for viewing your camera's image. Utilizing a 0.33-inch black-and-white CCD (charge-coupled device) image sensor, the Sylvania SY2500's camera includes a 3.7mm wide-angle fixed lens and delivers a resolution of 420 horizontal TVL (TV lines). Excellent in low-light conditions, this camera can receive a usable picture at a minimum illumination of 0.5 Lux. The Sylvania SY2500 camera and monitor both run on 12-volts DC power adapters (included), and the camera can operate in temperatures ranging from -14 to 122-degrees Fahrenheit.

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.

Great baby monitor,
By
This review is from: Sylvania SY2500 2.4 GHz Wireless B/W Video Security System (Electronics)
When we found out we were expecting a baby, this is the first thing my husband bought. This little unit works great! We have the camera mounted in the nursery and the video monitor in the living room. We get a clear picture with great sound. We can even hear the birds chirping outside our baby's window. The best part? We can see our baby even with NO lights on in the nursery. The t.v. monitor is so light, it can be carried anywhere in the house and plugged in.
