York City who, together with her husband, Albert Brown, patented the 
first home security system.
Brown got the idea for the security 
system because she and her husband worked long hours as an electronics 
technician, and she often found herself coming home to their apartment 
and being by herself late at night.
The system that Brown 
invented involved a sliding camera that could capture images through 
four different peepholes in her door, TV monitors to display the camera 
images and two-way microphones that allowed her to talk with anyone 
outside her door. 
There was also a remote to unlock the door from a distance and a button to alert police or security.
This system paved the way for modern security systems, and has been cited in at least 32 patent applications that came after it.

America has been the benefactor of the love and courage of women since the day they stepped into the New World we now call America.
Women are problem-solvers both in and out of the home. That’s likely why many life-changing inventions and discoveries point to an American woman. They’ve given us solid leaders and inventions that transformed life, faith, family and the American Dream.
How important women are to the success of our great country.
Women are the heart of America, and America owes her women the same.
