The technician was friendly yet professional. He stated that he'd been doing that type of work for 15 years which was very reassuring to us. Two new color touchscreen control panels, door sensors, three external cameras and one internal camera was installed. In addition the existing window sensors were connected to the system. He also took time to walk us through how to use the system. The company has also offered to continue providing support as needed. Needless to say, we are very more

The folks at American Guadian Security Systems helped us map out the system that is right for us. Brant Henke discussed all the options with me, and provided knowledgable and reasonably affordable options. The installer came out on time, (And was even a few minutes early!) The installation was done in under two hours, and the he took the time to explain the system, making sure we understood everything before he left. The installer was courteous and wore a mask the whole time he was in our home, which we really appreciated. If you're looking to install a security system for your home, I highly recommend more

Good day! My name is Dr. Roosevelt Isom, Jr. and I have been a customer with American Guardian for roughly 15 years! Since day one, they have always made me feel important as well as ensuring my family and I were catered with outstanding customer service! I would highly recommend American Guardian to any and every body who needs their home protected. Further, if you already have a carrier, I would definitely suggest you that you at least give them a call to inquire. I know the manager and receptionist by name and we're always glad to hear from one another. I am so glad that I have them protecting my home and will continue until the end!

Find the Answers to Your Questions About American Guardian Security

Frequently asked questions from our customers

Do you require a contract?

No Contract – No Problem

American Guardian offers month to month monitoring options or agreements with one, two, or three years rate lock in provisions to take advantage of our occasional monitoring rate sale promotions.

Do you background check your installers?

Employees Not SubContractors

You’ll be pleased to know that unlike many of our local competitors our Technicians are pre-screened employees instead of sub-contractors. This way we can provide a high level of training, quality control and supervision.

I have some unusual security requirements, can you still help me?

No Cookie Cutter Approach

Some companies use the cookie cutter or one-size-fits-all approach with their customers. With these companies each customer receives the same plain vanilla security system. However, with American Guardian our security professionals sit down with the customer and recommend equipment offerings based on their customer’s unique needs.

What type of monitoring do you offer?

Best In Class Monitoring

With American Guardian you receive premium, best-in-class monitoring. Unlike our competitors who only offer a single monitoring station platform, each American Guardian customer is monitored simultaneously by five (5) redundant, interconnected monitoring stations for the ultimate in redundancy and protection.

Are you local to Atlanta?

Locally Owned and Operated

You will be happy to know that we are not a branch or an affiliate of some out of state or foreign corporation like so many other security alarm companies in the Atlanta area are now-a-days. We are locally owned and headquartered right here in the Atlanta area. And we’ve been here since 1985!

I already have a security system at a great price, can you still help me?
