the x10 rocks, you can do a lot with it and its simple.you can set up the security camera,its got a sensor ( if you want to hook that part up) so the camera will trigger your vcr to record if someone walks by, if youve only got one vcr bt want to watch it in different rooms, the x10 can send a signal anywhere to another tv or computer..its great, and they are always coming out with cool new stuff, check them out... X10.com or X-10.com
