Protect your home, family or business with this wireless video surveillance system by Sylvania. Easy to install and operate, it uses the latest 2.4GHz wireless technology to provide a 300' open-field transmission range. Just mount the camera to the wall or desktop with the included bracket, plug-in the 5 high-resolution, black and white monitor and adjust the antenna. The camera features infrared emitters for low-light viewing and listen-in audio communication with the monitor. Includes 2 power supplies, RCA cable and warning decals. Auto-scanning option rotates picture between a maximum of 4 different cameras (each sold separately). Imported.
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.
- Signal distance: up to 300-feet (with clear line of site)

- 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.
What's in the Box
Wireless camera with camera stand, 5.5-inch monitor, 2 AC adapters (monitor and camera), RCA A/V cable, owner's manual/warranty card, screws and anchors, set of warning decals, trilingual owner's manual, and warranty card.

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.
I HAVE ABOUT 6 OF THESE UNITS.
2 I USE 24 HOURS A DAY.
4 ARE FOR BACK-UP UNITS BECAUSE THEY DO NOT MAKE THIS MODEL ANYMORE.
THE CAMERA WORKS OFF OF 12 VOLTS AND THE NEW ONES WORK OFF OF 9 VOLTS.
I HAD A 9 VOLT CAMERA AND TRIED TO MAKE IT WORK OFF OF 12 VOLTS - NO LUCK SO IT WENT IN THE TRASH.
THE SYSTEM WORKS VERY WELL .
