Women in Security

An African American woman paved the way for the CCTV systems we use today.

Often, when we think of technology or security professionals, we picture the characters from the IT crowd or a male-dominated office where even the workroom pet plant named Peeve goes by him/he pronouns.

As a result, the phrase, Women in Security, often finds itself misplaced at the start of a joke when in reality, women are far from it. Did you know that in 1966, an African American woman called Marie Van Brittan Brown invented the first modern home CCTV security system after a spate of robberies in her neighbourhood.

Mrs Brown created a CCTV system hidden in a peephole, powered by a motor which moved up and down the door when she had visitors at her doorstep. She also developed a wireless radio that projected the recorded image of the visitors onto a television monitor. The inventor is also the mastermind behind the system that allows the resident to talk to the visitor through two-way microphones and remote control option to lock and unlock the front door from a safe distance. Mrs Brown filed a patent under the title: “Home Security Utilizing Television Surveillance,” which she received in 1969.
