Patrol Services

Founded by Sam Post over 60 years ago. Post Alarm is a family-run business committed to protecting our neighborhoods in Southern California.

Complete commercial, home security & alarm monitoring in Los Angeles, Orange County, and SoCal since 1956.


One of the many benefits of choosing Post Alarm is our Commercial Patrol Service. From commercial or industrial spaces to town homes, apartment complexes, and dedicated patrol for communities, we can provide patrols of common grounds, parking garages, and pool areas to monitor and secure the private driveways, streets, or parking lots around your commercial space.

When alerted, our highly-trained patrol officers will respond to your location, inspect the premises, and notify you of their investigation as well as report back to our Central Monitoring Station for the dispatch of the appropriate authorities if there is an actual alarm or fire.

If you’re in need of professional Officer Services in Southern California, we can provide highly trained patrol officers. Your employees or tenants will feel happier and safer knowing there is someone looking out for them.
