I live in apartments with windows facing the parking lot. For some time now, I have thought about hooking up a webcam of some kind and pointing it out the window towards where I parked. The logistics of running a long USB cable from my computer to the appropriate window prevented me from doing it that way. A wireless WiFi webcam might be the perfect solution, but not everyone has a WiFi network (and these cameras can be a bit pricey).
The Lorex LW2201 is an interesting compromise between legacy equipment (old fashioned cameras) and modern wireless technology. The camera itself is designed to be usable outdoors, meaning it is in a rugged metal enclosure complete with an adjustable hood that slides forward to cover and protect the camera lens. It is a color camera, but in low-light conditions, it clicks in to "night vision" mode and the image goes to black and white. A ring of infrared LED lights around the lens light up, allowing you to see an image even in complete darkness. There are no wires -- the camera has an antenna that attaches to the back, and a power cable that plugs in to an AC adapter. Bolt the base somewhere, run the power cable, and you are set from that side.
Elsewhere, a tiny receiver -- about the size of a deck of playing cards -- can be plugged in, and an antenna is attached to allow it to receive video from the camera. Video and audio outputs come out of the receiver (cables are included) and then run to a monitor or TV, or in to a recording device. If you just wanted to keep tabs on your car overnight, you could use a cheap VCR and let it record in 6-8 hour mode.
Overall, setup of one camera to the one receiver is very simple. The receiver can support multiple cameras, and can be set to flip between the cameras (full screen), or split the screen up to display four images at a time. I cannot comment on those features, as I only have the one camera. A button is pressed on the receiver to get it in to a scanning more, then you have to press a button on the camera within 30 seconds to let them sync to each other. It seems easy enough.
The camera does have sound, so if it is mounted outside, you can hear a bit of what is going on, but don't expect miracles. It's not quite as sensitive as a home movie camera typically is. So, overall, you have wireless color (in light) or black and white (in darkness) video with sound, transmitted to a receiver within a few hundred feet.
Now, the downsides:
First, range is very limited unless you have an open area with no obstructions. I hooked the received up to a TV in my livingroom, then tried to use the camera in the bedroom connected to the same wall that the TV is against. Even though the range was only about 15 feet between camera and receiver, signal quality was too poor to lock on. This was due to the bedroom having several large metal shelving units which obstruct the signal. If the room was empty, I doubt there would be such problems.
Video quality is also quite poor. The camera sends a digital picture that looks more like a YouTube video than a video camera image. You can toggle between high speed but low resolution (thus, motion is good but image is blocky), or a slower high resolution image. In bright light, the high resolution image looks very good -- a bit "digital" but totally watchable. The frame rate slows way down, though, so it comes across looking like a traditional security camera clip you'd see on a TV news program.
Overall, the camera seems well built and designed, but wired cameras I have seen provided a better picture than this wireless system. However, in situations like mine, a wireless solution is a MUCH easier choice. As long as you can tap in to power, you can mount this camera anywhere within range and get a totally usable image without any wiring or network configurations.
For my specific uses, though, I think my next effort will be with a WiFi camera. Since I already have a network which completely covers my home, that may produce better results than this dedicated security system.
Instructions were clear, packaging was nice, and setup was simple. It does what it does, and the wireless "plug and go" is very neat. Just keep in mind the designed use -- picture quality may be worse than you expect, and range may be more limited than you expect.
Overall, a very good product for it's intended audience.
