Oh my God Guardian has the nicest employees working for their company. They are very informative. They take their time to let you understand their equipment. They’re not out trying to make a sale or just beat you out of money. They really want to help and that makes a difference when you’re dealing with a company Tim came out today and I feel 100% satisfied with the work that he did for me. I appreciate him greatly and I suggest anyone just not just the people are kind and nice. Their service is A1. You won’t regret it. Thank you, Guardian.

I signed up with Frase And then Guardian bought them. When I finally reached out To them to fix some issues, they have been completely responsive and John their technician has been amazing! He stayed from 8 AM until past 6 pm putting up my cameras and fixing my alarm system And was genuinely helpful, kind, and patient the entire time! In the same age where Customer Service tends to be so poor he was Absolutely phenomenal!!

Michael, the technician who came to update my Guardian Alarm system and install a security doorbell camera did an excellent job. His knowledge and experience enabled him to work quite efficiently to complete the installation.
Michael took the time to patiently show me how to install and use the new App for my new system. I'm a happy camper!
