Serving Orange County, Los Angeles, And San Diego Businesses

Protecting premises, people, and valuable assets is a critical component of your overall business strategy. When it comes to fire and intrusion detection, video surveillance (CCTV) and access control systems, the importance of installing top-of-the-line systems backed end-to-end by exceptional support services cannot be overstated.

As in all tech-based industries, security technologies have evolved, with advancements in capturing, storing, and sharing critical data becoming more remarkably accurate than ever before. You can observe these capabilities in a live demonstration at our Command Center.

Beyond the necessary technology, however, JMG SECURITY SYSTEMS takes the most pride in the committed, trusted partner relationships we’ve forged with Southern California’s most prestigious names in business, sports and entertainment. Our clients know they can consistently rely on us to exceed their expectations, and our outstanding track record has earned us a reputation as the region’s premier provider of comprehensive commercial security systems.

Security Myths, Answered

“All monitoring is the same.”

Response depends on the operator, the protocol and the servers behind them. Ours run on dual-redundant servers in two states.

“Cameras alone stop break-ins.”

Video records. Intrusion detection, lighting and a monitored response are what interrupt a break-in.

“Monitoring is just a phone line.”

JMGCONNEX, our own private radio network, keeps alarm signals moving through earthquakes, floods and storms.
