About JMG
1987
Our goal is to provide a more client-centric approach to the security system industry. Founded by Ken Jacobs and Mike Christensen, JMG SECURITY SYSTEMS began operations in 1987.
In 1987, both Ken Jacobs and Mike Christensen left executive positions with large commercial alarm companies to find a better way to provide excellent customer service in their industry. From humble beginnings in a garage, they identified a market in serious need of a higher level of customer service and support than had ever previously existed.

Security system companies have long been known for their poor customer service and both Ken and Mike decided the time was right to demonstrate what true service excellence can be when providing security systems for businesses. JMG SECURITY SYSTEMS is now the premier business security systems consultant and installer for Southern California companies and remains committed to providing the excellent service its reputation was founded on.
JMG’s offering of commercial security systems combines the latest cutting edge technology with expert and custom tailored solutions to businesses across Southern California who are looking to install or upgrade their commercial security systems. The brilliant staff that have supported this vision since 1987 are at the heart of what makes JMG SECURITY SYSTEMS such a reliable, service-oriented company and what drives the positive culture that Ken and Mike are still so proud of.
To accomplish these goals, we work continuously to present security solutions at the forefront of technology while improving internal ordering and inventory systems and maintaining award-winning customer service. A strategic decision was made to focus entirely on the Southern California market to ensure that whenever our clients need assistance, they can always rely on the team at JMG SECURITY SYSTEMS.
JMG SECURITY SYSTEMS is proud to announce our expansion into the California Central Coast. We offer our best-in-class service from Paso Robles south to all Southern California.
To deliver the absolute best customer service experience in the business security system industry possible.
Our story, our team, our resources, and our vision are all centered on one mission.
At JMG SECURITY SYSTEMS, we believe we honor that mission each and every day.

To deliver ‘Best-in-Class’ commercial security systems, customer service is what drives us each and every day.
“I have never worked at a company where every single person is equally dedicated to best-in-class customer service!”
The JMG family has grown heavily from within and any outside talent that joins us often shares similar feelings. We’ve worked hard since 1987 to instill and nurture this vision from day one, and it would not be possible without our incredible team.
