Marie Van Brittan Brown
(1922-1999)
The Brown’s invention laid the foundation for later security systems that make use of its features such as video monitoring, remote-controlled door locks, push-button alarm triggers, instant messaging to security providers and police, as well as two-way voice communication.
Their invention is still used by small businesses, small offices, single-family homes, and multi-unit dwellings such as apartments and condominiums.
The Browns’ patent was later referenced by thirteen other inventors including some as recently as 2013.
