Is this even practical anymore? A non-technical person can set up video surveillance on their home for a couple hundred bucks. Why wouldn't a criminal do that? I think the days of the FBI planting a microphone in a lamp on Tony Soprano's basement are over.
It's hard to set up video surveillance in your home without inadvertently providing much of the surveillance data the law enforcement officers were after, especially for non-technical people.
