Marie Van Brittan Brown is the reason home security systems exist today. Born in 1922 in Queens, New York, Brown was a nurse who often worked irregular hours, leaving her concerned for her safety at home. With crime on the rise in her neighborhood and slow police response times, she took matters into her own hands.
In 1966, Brown and her husband Albert patented the first home security system, which included a camera that could slide up and down to view through multiple peepholes, a microphone for two-way communication, a remote-controlled door lock, and an alarm system. The setup even allowed her to see visitors on a monitor in another room—an early precursor to modern closed-circuit television (CCTV) surveillance.
Although her invention was initially designed for home use, it laid the groundwork for the entire home security industry, influencing everything from video doorbells to modern alarm systems. Despite her groundbreaking work, Brown remains relatively unknown compared to other security pioneers.
Her contribution proves that necessity breeds innovation, and her foresight continues to protect millions of homes and businesses today.
