We attribute our success to our dedication to service and customer satisfaction.

We pride ourselves on taking the time to get to know your unique needs and expectations. Then we design a security system that matches those requirements. We believe a security system should be personalized, not stamped from a mold and sold as if “one size fits all.”

AES has been servicing clients in Fairfield County and Westchester County since 1973. Over the years, we have protected nearly 4,000 homes and businesses.


Who We Are.

Advanced Electronic Systems is a Norwalk-based security provider specializing in the design, installation, service and monitoring of security and fire alarm systems for both residential and commercial markets.

Our roots date back to 1973. In 1999, Howard Friedman purchased the company and created a simple mission: 100% customer satisfaction.

We are able to attain this goal because AES believes that Local is Better! With nearly 4,000 clients, we are large enough to have the necessary resources available 24/7 and have a human being answer every customer phone call. Yet, we are small enough to know all of our customers by name, and never too far away to help. 2017 #1 Ranked Residential Alarm Company  in CT rated Advanced Electronic Systems as the #1 Ranked Residential Alarm Company in CT in 2017.
