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.
