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 reports more than 20 years in commercial security and work for 900+ California businesses. Its core offer pairs camera installation with live remote monitoring. It also fields guards and patrols.
Live video monitoring and virtual guarding
The company describes a monitoring center in Los Angeles, staffed around the clock. AI detection flags activity, and live agents verify it, issue warnings over two-way audio and call police. It says this approach can cost up to roughly 70% less than traditional guards.
Guardian Integrated Security lists hybrid guarding, which blends on-site officers with AI remote monitoring. It also names automated license plate recognition and remote guarding across multiple locations. Mobile surveillance units round out the remote offer.
CCTV and security camera installation
Guardian installs NDAA-compliant cameras for commercial sites. Its CCTV work covers service and repair as well as new installs and monitoring. The process it describes starts with a site evaluation, moves to installation, then continues with ongoing monitoring.
Security guards and vehicle patrol
The company provides on-site guards and vehicle patrol for sites such as construction projects, parking lots and retail stores. It states that each guard passes an interview, a background check and drug testing. It also offers to match or beat a competitor's price.
Reviewers most often mention quick scheduling, fast camera installs, steady night patrols and clear incident reports. The office keeps weekday hours of 8:00 am to 5:00 pm.
The company states it holds California PPO license #121089 and ACO license #7501, that its guards are licensed by the Bureau of Security and Investigative Services, and that it is BBB-accredited.
Guardian says it works for commercial and industrial property owners across Southern California, from small and medium businesses to large multinational corporations.
