Along with her husband, Marie Van Brittan Brown invented a security system


 

 

Marie Van Brittan Brown

(1922-1999)

 

 In 1966, Brown, along with the assistance of her husband, invented a security system which consisted of four peepholes, a sliding camera, television monitors, and two-way microphones.

 

 These items created a closed-circuit television system for surveillance also known as CCTV. With multiple peepholes, the sliding camera was able to capture images of people who were different heights. 

 

The two-way microphones allowed Brown to communicate with the person outside. She also had a remote that would allow her to unlock the door at a safer distance. Lastly, she could press an emergency button that would send an alarm to police or security.
