X.10 and Home Security?

cancerboy asks: "After last night, I need to set up some home security since a kid put a brick through my bay window. One of my primary concerns is basic video surveillance. I am aware of X.10 and know that any number of vendors sell X.10 cameras. However, I am a complete novice when it comes to X.10 technology. One, I was hoping to get some pointers for getting started (considerations, HOWTOs, code libraries, etc). I am also interested in any opinions about the cost/benefit as well as any legal issues I might be facing by installing video surveillance equipment. I live in an urban environment in a town house and I wonder if there are any issues with recording exterior shots that include public property."
