On this day in #BlackHistoryMonth✨we celebrate the life and contributions of Marie Van Brittan Brown, a nurse and the inventor of the 1st Home Security System.
"Her original invention consisted of peepholes, a camera, monitors, and a two-way microphone. The finishing touch was an alarm button that, when pressed, would immediately contact the police. Her patent laid the groundwork for the modern closed-circuit television system that is widely used for surveillance, home security systems, push-button alarm triggers, crime prevention, and traffic monitoring." - Pamela Rosario Perez
