A study by the Urban Institute’s Justice Policy Center discovered that Baltimore’s network of much more than 500 cameras has driven down crime in most areas.

Each camera wirelessly transmits photos up to 100 ft. to the receiver, which sends the pictures through cable to either a Tv or a VCR (Photo 2). You pick which of the 4 camera photos you’d like to view by pushing a button on the receiver or the remote handle (Photo 3).
