When a fire safety system goes offline, the clock starts — and so does your liability.
Guardian National Security provides BSIS-licensed fire watch guards for Los Angeles construction sites, hot work projects, sprinkler outages, and fire code compliance. Our guards patrol for hazards, maintain detailed logs, and are trained to respond the moment something goes wrong — keeping you compliant and your property protected until systems are back online.
When a sprinkler system fails, or an inspector requires coverage, you can't afford to wait. We dispatch trained, documented fire watch guards within hours of your call.
Serving all of Los Angeles County, dispatched live 24/7.

A production schedule doesn't leave room for security problems — every delay costs the budget.
Guardian National Security protects film and TV sets across Los Angeles, from controlling set access and managing crowds to safeguarding expensive equipment and keeping unauthorized people away from talent. We understand how productions run, and our guards work around your call sheet, not against it.
Every guard is BSIS-licensed, trained under retired police officers, and GPS-tracked shift to shift. Available armed or unarmed, day or night, on location or on the lot.
It's the kind of professional presence that protects your production and reflects well on it.
Serving all of Los Angeles County, dispatched live 24/7.
🎬 Set access • Equipment protection • Crowd & talent security

Vehicle Patrol Services in Los Angeles
One fixed post can't cover a sprawling property — and intruders know it.
Guardian National Security's marked patrol vehicles run randomized routes across your site, so there's no predictable pattern to wait out. It's the right coverage for large lots, multi-building campuses, and after-hours protection where a single guard at the door would leave too much ground unwatched.
Every patrol is BSIS-licensed, GPS-tracked, and documented — you receive a record of every route run and every check completed. No guesswork about whether your property was actually covered.
Serving all of Los Angeles County, dispatched live 24/7.
🚗 Marked vehicles • Randomized routes • GPS-verified
