Marie Van Brittan Brown invented a video home security system

 


Marie Van Brittan Brown

 (October 30, 1922 – February 2, 1999)

 

Inspired by how long it would take the police to arrive in her neighborhood, Brown invented the first home security system.[3] Her work hours were not the standard 9am – 5pm, and the crime rate in their Queens, New York City neighborhood was very high.[4] 

 

Marie started her invention by creating three peepholes[4] in the door to provide access for tall and average height people along with her children. 

 

The next step was setting up a camera that could adjust from peephole to peephole to allow people inside the house to look outside to see who was there. 

 

Marie wanted to find a way to view who was outside the house from any room and decided a wireless television system would work best.

 

 To do this, she used a radio-controlled wireless system that could stream the video to any television in the house.  Along with the video system, Marie and her husband created a two-way microphone system that would allow for communication between the family and the person at the door. She also created a system to unlock the door remotely.
