Modern home security systems, which come with features like video monitoring, remote access, and intelligent alarms, are a testament to the pioneering work of African American inventor Marie Van Brittan Brown. Brown co-invented the first home security system in 1966. It was so innovative that it served as the model for contemporary home security and alarm systems.
Let’s look at how this bright woman transformed the way we secure our homes long before smart homes were even an idea.
Who Was Marie Van Brittan Brown?
In Queens, New York, Marie Van Brittan Brown was born in 1922. Her husband, Albert Brown, was an electronics technician, and she was a nurse. Safety was a top priority because they both worked odd hours. Police response times were delayed, and they didn’t always feel safe in their neighbourhood.
Marie, therefore, came up with a solution rather than waiting for one.

The Invention: World’s First Home Security System
In an attempt to protect her family and frustrated by the lack of reaction from local police enforcement, Marie and her husband created a closed-circuit television (CCTV) system. This was the first patented home security system, so it wasn’t just any do-it-yourself job.
Here’s what their 1966 system included:
-
Four peepholes at different heights in the front door
-
A motorised, adjustable camera that could slide between peepholes
-
A monitor inside the home to view who was outside
-
A two-way microphone system for communication
-
An alarm button that contacts police or security instantly
Their 1966 application and 1969 invention (U.S. invention #3,482,037) established the groundwork for modern smart home and video doorbell technology.
A Legacy That Lives On
Marie’s invention wasn’t just innovative—it was revolutionary. Her system introduced the concept of:
-
Remote surveillance
-
Real-time video monitoring
-
Direct emergency alerts
The fundamental ideas of her creation are now the foundation of reputable businesses like Ring, ADT, and Nest.
Millions of families are able to sleep more easily at night due to Marie Van Brittan Brown, even if her name isn’t as widely recognised as it ought to be. She genuinely altered the rules of home safety.
Recognition and Impact
The patent owned by Marie and Albert Brown served as a template for later advancements in home security. After the invention was highlighted in The New York Times, demand for home security systems skyrocketed.
More significantly, she created opportunities for women and African Americans in STEM subjects, where representation was and continues to be required, in addition to the tech industry.
She is now hailed as a groundbreaking inventor, particularly during Women’s History Month and Black History Month.
