29 de enero de 2014 a las 11:21 Home Security Inventions – Marie Van Brittan Brown While home security systems today are more advanced than ever, back in 1966 the idea for a home surveillance device seemed almost unthinkable. That was the year famous African-American inventor Marie Van Brittan Brown, and her partner Albert Brown, applied for an invention patent for a closed-circuit television security system – the forerunner to the modern home security system. Brown’s system had a set of four peep holes and a camera that could slide up and down to look out each one. Anything the camera picked up would appear on a monitor. An additional feature of Brown’s invention was that a person also could unlock a door with a remote control. A female black inventor far ahead of her time, Marie Van Brittan Brown created an invention that was the first in a long string of home-security inventions that continue to flood the market today.
