Product Description
Amazon.com Product Description
The Sylvania SY4225 2.4 GHz Wireless B/W Video Security System is a simple, reliable, and highly economical solution for most basic remote monitoring needs. The easy-to-install Sylvania SY4225 camera features wireless technology to save you the hassle of cable connections, making it an ideal solution when portability is required. Not only is this system compatible with all Sylvania 2.4 GHz wireless devices, but with built-in listen-in audio and the receiver's ability to autoscan up to four separate cameras, this system can turn any TV into a video security system that is great for monitoring situations where installing cables are not convenient.
The SY4225's camera utilizes a black-and-white CMOS (complimentary metal-oxide semiconductor) image sensor, with a 3.7-millimeter fixed lens. This unit delivers a standard-resolution picture with 240 horizontal TVL (TV lines), even in no-light conditions down to a minimum illumination of 0 Lux via its built-in IR (infrared) LEDs (light-emitting diode), and includes a built-in condenser microphone. The Sylvania SY4225 camera runs on 12-volt DC power via an included AC/DC adapter or can run on eight AA batteries for complete portability, and has an operating temperature of 14 to 122 degrees Fahrenheit.
The SY4225's monitor utilizes a 2.4 GHz frequency to allow for signal reception through walls and ceilings, or from up to 300-feet away with a clear line of sight, and a 5.5-inch black-and-white picture-tube display. The Sylvania SY4225 monitor includes a standard RCA composite video output connection that easily connects to most VCRs for recording, and runs on 13-volt DC power via an included AC/DC adapter or on 10 C batteries for complete portability. This receiver can accept signals from up to four cameras simultaneously, allowing you to autoscan all four or display full-screen images of a single camera, and has an operating temperature of 14 to 122 degrees Fahrenheit.
Technical Features:
- Signal distance: up to 300-feet (with clear line of site)
- Light sensitivity: minimum illumination of 0 Lux within range of IR LEDs
- Horizontal resolution: 240 TVL
- Camera and monitor operating temperatures: 14 to 122 degrees Fahrenheit
- Camera dimensions: approximately 6.1 x 5.8 x 7.1 inches (W x D x H)
- Receiver dimensions: approximately 4.45 x 3.3 x 2.8 inches (W x D x H)
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.

Wireless a good idea?...... maybe not.,
By Benjamin S. Edwards (Trenton, TN United States) - See all my reviews
This review is from: Sylvania SY4225 2.4 GHz Wireless B/W Video Security System (Electronics)
This system is a piece of cake to install. Two people make it easier and faster. Make sure you have electrical outlets at both locations where the monitor and camera will go. Then, FIRST take the camera and set it in the area where you will later mount it. Then set up the monitor where you want it. Good picture? Congratulations! Poor picture? Try adjusting the antennas on each device to hopefully achieve good reception. (Poor reception will have rolling lines through it.) Still poor reception? Box it up, send it back, and buy a wired system. Perhaps the First Alert brand. It worked well for me.

Wonderful - I Love it!!,
By Montana Gal (Musselshell, MT United States) - See all my reviews
This review is from: Sylvania SY4225 2.4 GHz Wireless B/W Video Security System (Electronics)
I bought this unit to monitor my barn. I have 17 mares to foal and want to keep a very close eye on them. My barn is over 300 feet away from my house and this unit works beautifully. The monitor works with up to four cameras. I now have 3 cameras hooked up to my unit and am considering buying the 4th camera. Its easy to install, easy to run. I have a crystal clear picture in one stall, and a not quite as good of pictures in the other two stalls which are a little further away. I love this product.

This review is from: Sylvania SY4225 2.4 GHz Wireless B/W Video Security System (Electronics)
We were pleased to get this as quickly as we did, having ordered it July 5, and receiving it July 23 - much faster than the estimated delivery date of Aug 11-26!
We previously tried the Baby Quiet Sounds system purchased from Babies R Us for the same price - about a BenFranklin. This we returned in a few days because 1. There was a lot of interference/poor signal and 2. The wall transformer (the plug) for both the monitor and camera became extremely hot - almost too hot to touch. NOT SAFE! Other reviewers have commented on these flaws. Well this device was a snap to "install" All you do is plug both camera and monitor in and turn them on. There are 4 channels that can be used. So up to 4 cameras can be hooked up. You can set the monitor to scan through all 4 channels for a variable number of seconds. You can output the video signal to a VCR - Sylvania apparently sells a timelapse VCR to record long periods of time on 1 tape. We use it as a baby monitor. It has infrared capability so you get an image even in the dark. We set the camera a few feet from our kid, and can see her head in the dark although without fine detail. We place the monitor downstairs or upstairs in our bedroom. The signal is clear. It uses 2.4 GHz. We have a wireless computer network, 2 wireless phones, and our cell phone which all use 2.4GHz but so far the signal remains strong. Only the occasional line or 2 through the image. The plugs still get hot on this one too, but not as hot as the Quiet Sounds. It's probably best to leave the monitor off most of the time, and just flip it on when you want to see what's going on. Unfortunately there is no setting for you to just get audio, so we are using the audio baby monitor we already had to do this. Considering this was priced at One hundred fifty originally, it seems like a good deal, and so far we are pleased with the purchase.
