Step-by-step explanation:
Marie Van Brittan Brown (1922-1999) was an African American inventor. She is best known for inventing the home security system. In the 1960s, Brown, who lived in New York City, was concerned about the rising crime rates and slow police response times in her neighborhood. She wanted to find a way to increase the security of her home.
Brown, along with her husband, developed a closed-circuit television system that allowed them to monitor the exterior of their home and communicate with visitors at the door. The system included a camera, a monitor, and a two-way microphone. They also added a remote control to unlock the door.
The Browns patented their invention in 1969, and their home security system laid the foundation for modern security systems. Today, many homes and businesses use similar technologies to protect their premises.
