American Guardian Advantages

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

  • Our corporate headquarters is located in Norcross, Georgia, incorporated in 1985, and we have been providing excellent service to Georgians for over 34 years.
  • American Guardian is Georgia’s oldest and most respected ADT Authorized Dealer.
  • You deal directly with us instead of a ADT Dealer Network or an out of state ADT Dealer.
  • By dealing with our locally based company you will receive better service and much faster response than that of out of town companies and dealers who use sub-contractors instead of employees, and frequently don’t even maintain offices or service centers in our state.
  • We use Service Technicians that are employees rather than Sub-contractors. This way we can provide a higher level of training, quality control and service to our valued customers.
  • By activating your ADT security monitoring through American Guardian you enjoy the best of all worlds. Your system activation is performed by a locally based ADT Dealer who is also Georgia’s oldest, most respected ADT dealer. Additionally, you receive world class monitoring by ADT Security Services, the world’s largest and most respected security provider and the only security company that provides monitoring by five fully redundant monitoring stations to each of their customers.
  • Unlike many other security companies, when you activate your system through American Guardian, you own your system, you are not leasing it. If you are considering activating through any other company be sure to read their disclaimers to make sure you own the equipment. Most national security companies will put you in a lease.
  • With American Guardian, you receive the latest wireless security system technology. We are one of only a very few companies that offer the newest wireless systems. Most of our competitors are still selling old wireless systems that have not been upgraded in years.

Fill out the form and an ADT security specialist will call you to discuss your security options.

With Atlanta owned and operated American Guardian, you pay only a $99 one time installation fee and only $33.99 monthly for 36 months to own your residential security system.

Again, this is not a lease. With many of our competitors like Brinks, Alarm Force and others you are only leasing the equipment. You never own it. This puts the security company in control and if you are not happy with their equipment or service you have to replace the equipment and start all over again with another company.
