Yes, I have a few of them. They work O.K. But remember, if someone walks between the sending and receiving units, the signal fuzzes out. The farther apart they are, the easier it is to kill the signal. I also have a few wired units. They work fine for the price. They are susceptable to sunlight damage if the lens is pointed directly east or west where bright sunlight can burn out the chip, so put them under an eaves or something when planning the installation. I have mine about 50' max between the senders and reciever.
As for their VCR commander, it really does work, if you can figure out how to program it. Google search for x10 VCR commander setup for help. I set up a couple of eagle eye motion sensors and set up the VCR commander, and a couple cameras. I threw a 4 hour tape into the VCR figuring that would be enough, since it was supposed to record for 5 minutes after motion ceases.
When I came home, the tape was ejected... all used up. I reviewed it to see what happened. A robin flew up on my gate, trigger the motion sensor, pooped on my sidewalk and flew away. Then 5 minutes of nothing. Then the robin came back from the other direction, landed on my gate, pooped and flew away... you get the idea. 48 clips of a robin pooping on my gate.
Enough of that. I stopped using the VCR commander and the eagle eye motion sensors. Instead, I hooked up the cameras to a PC with video capture card and a motion sensing video capture program. It works much better and records to the hard drive. It senses motion by comparing the picture from time to time and is easily adjusted to account for something like a bird or rabbit but still pick up large dogs and people. You can set it to FTP video clips or stills to a website or e-mail when there is an event. Lots of options.
