The military origins of closed-circuit television (CCTV) cameras can be traced back to Soviet Russia during Stalin's reign. In 1927, Russian scientist Léon Theremin connected a video camera and television to form one of the earliest CCTV systems in history. It was used to watch visitors coming to the Kremlin in Moscow.
When did cameras start being used for security? In September 1968, Olean, New York was the first city in the United States to install CCTV video cameras along its main business street in an effort to fight crime. Marie Van Brittan Brown received a patent for the design of a CCTV-based home security system in 1969.
