Today, millions of homes rely on security cameras, alarms, and smart doorbells to keep families safe. But the foundation for these technologies began with one groundbreaking invention created by Marie Van Brittan Brown, a nurse from Queens, New York, in the 1960s. Continue reading to learn more about who invented home security, what inspired her, and what the first system looked like.
A Problem That Needed a Solution
In the mid-1960s, Brown lived in a neighborhood in Jamaica, Queens, where crime rates were rising. She often worked late hours as a nurse, and her husband, Albert L. Brown, an electronics technician, also had irregular work schedules. This meant Brown was frequently home alone at night. The situation made her uneasy—especially when someone knocked at the door, and she had no safe way to see who it was.
Police response times were also slow in her area, which increased her concern for personal safety. Instead of accepting the risk, Brown decided to invent a solution that would allow homeowners to monitor their front door without opening it.
Inventing the First Home Video Security System
In 1966, Brown and her husband developed what is widely recognized as the first modern home security system. Their invention combined several technologies into a single safety solution.
The first home security system included:
- Four peepholes placed at different heights on the door
- A sliding camera that moved between the peepholes
- Television monitors inside the home to view visitors
- A two-way microphone and speaker for communication
- A remote-controlled door lock
- An emergency alarm button to contact police or security
The camera transmitted images to a monitor inside the house, allowing the homeowner to safely see who was outside before opening the door. The two-way audio system allowed communication with the visitor without direct contact.
In August 1966, the Browns filed a patent for their invention, titled “Home Security System Utilizing Television Surveillance.” The U.S. Patent Office granted it in 1969, officially recognizing their groundbreaking innovation.
The Beginning of Modern Home Security
Brown’s invention was revolutionary because it introduced key features that are now standard in modern security systems. Concepts such as video surveillance, remote door control, two-way communication, and emergency alerts all trace their roots back to her design.
Her patent has since been cited by dozens of other inventions and helped shape an entire industry. Today, home security systems—including video doorbells, surveillance cameras, and smart alarms—are part of a multi-billion-dollar market built on the ideas Brown pioneered.
A Lasting Impact on Homeowners
For homeowners, Brown’s invention changed how people think about safety. Before her system, homeowners had limited ways to monitor their property or verify who was at the door. Her design gave people the ability to see, communicate with, and respond to visitors safely from inside their homes.
More importantly, it introduced the idea that technology could give homeowners greater control over their personal security.
A Legacy That Lives On
Although Brown passed away in 1999, her invention continues to influence modern security technology. From CCTV cameras to smart home monitoring systems, many of the tools used to protect homes today are built on the concepts she first introduced.
What began as a practical solution to a personal safety concern ultimately transformed home security around the world—making Marie Van Brittan Brown one of the most influential innovators in the history of residential safety.
Frequently Asked Questions
Who invented home security?
Marie Van Brittan Brown invented home security in the 1960s. Living in Queens, NY, she often felt unsafe when home alone, especially at night. Living in a neighborhood with rising crime and slow police response times, she wanted a safer way to see and communicate with visitors at her door without opening it.
How did the original home security system work?
The system used a camera that could move between several peepholes in the front door. The camera sent images to a monitor inside the home, allowing the homeowner to see who was outside. It also included a two-way microphone, a remote door lock, and an emergency button to contact authorities.
How did this invention influence modern home security systems?
Brown’s invention introduced ideas that are now standard in home security technology, including surveillance cameras, remote monitoring, and two-way communication. These features are now common in smart security systems and video doorbells.
Do modern home security systems still use ideas from the original invention?
Yes. Many features in today’s systems, such as doorbell cameras, remote viewing, and two-way communication, are based on concepts first introduced in Brown’s original design.
