I got security guard services for my an event I was hosting and I got a guard on site with in a couple hours same day, highly recommended Guardian Integrated Security for your event security!
I called Guardian Integrated Security for security camera installation on a Monday and got all 6 cameras done on Tuesday. They are great to work with and move very fast and efficient. Thank you!
We've worked with Guardian Integrated Security for several years for night patrols at our property, and we've been very happy with their service. They're great to talk to, have a great response time, and provide consistently great service. Highly recommend!
About Guardian Integrated Security
Guardian Integrated Security is a security guard service in Chatsworth, California. It also works as a security system supplier, so its trade covers both people on a site and the cameras that watch it.
What a security guard company in Chatsworth takes on
Guardian's categories cover three strands: guard service, broader security service and the supply of security systems. In practice that means putting guards on a site, sending vehicles on patrol rounds, and fitting and watching cameras.
The company describes much of that watching as remote work. Its description says live agents based in Los Angeles review camera feeds around the clock, with AI tools flagging activity for a person to confirm. When something looks wrong, the agents can speak through two-way audio and call police. The firm also names virtual guarding and mobile surveillance units among its services.
Where Guardian Integrated Security puts its work
The company says its clients are businesses, from small shops to large corporations, with commercial and industrial property across California. Its website lists construction sites, retail stores and parking lots among the places its guards cover. It says its guards hold licences from the state Bureau of Security and Investigative Services and pass background checks and drug testing.
The description states two licence numbers, PPO #121089 and ACO #7501. It reports more than 900 California businesses served over 20 years. The firm also pitches a hybrid model, which it describes as pairing on-site guards with AI camera monitoring so a property needs fewer guard hours.
Guardian holds a 4.6 rating across 47 Google reviews. Reviewers most often mention speed, such as a guard arriving the same day or cameras going in the day after a call. Property managers also describe patrol and monitoring arrangements that have run for years, steady communication and regular reports on incidents.
The company says the first step is a call to set up a site security evaluation. After that, it describes installing the systems a property needs, then monitoring the site and keeping the owner informed.
