Security Systems

Founder Joe Giannini began protecting the streets in the Castro district of San Francisco as a patrol special officer in the late ‘60s. After a few years, Joe and his partner decided to work together and begin their own security business. They started installing simple wired alarm systems that would trigger a bell when activated.

Later on, they opened their own central station with only one alarm system being monitored full-time. Joe’s wife, Florence, managed the office and his youngest son, Ron, also started working there when he was a teenager. Currently, our business is being run by the third generation of our family.
