About Us

AT Systems is the premier provider of high-quality home and commercial security products and services in Columbus, Ohio. The company strives to be the one you will always call for services and facilities for fire, intrusion detection, closed circuit television, access control, and residential and commercial surveillance systems.

Where We Started

Starting out as Alarm Service and Repair, Inc., in 1970, AT Systems initially provided installation and repair service to Columbus area customers who wanted their existing alarm and security systems fixed or updated. This very first service offering would serve as the foundation for our present success and our complete range of home and office security systems.

In 1978, immediately after gaining loyal following among its Columbus customers as a reliable service provider and security systems specialist, AT Systems expanded its services to include security systems installation (for residential and commercial set-ups), front-end services, maintenance, as well as retailer and distributor for the latest advances in security and surveillance systems.

As a sign of emerging new services and the development of a new range of services that includes the latest advances in security systems technology, Alarm Service and Repair, Inc. formally became AT Systems.

Serving Customers and The Columbus Community

AT Systems has established itself as the benchmark in the safety and security services industry in the last four decades, serving the Columbus market with quality products, expertise and service. More and more new and repeat customers have come to rely on AT Systems for our quality service, professional and polite technicians and installation / repair teams, and great rates.

This is because AT System’s treats each customer like family – and this philosophy of family helping family is the key to all our efforts in improving our quality service and expertise. AT Systems has a lean, service-oriented staff focused on ensuring that our customers needs’ are answered to promptly and we guarantee that our staff will always be there to talk with you, and personally help you with your security needs, whenever you visit.

AT Systems is committed to improving safety and security not just of its customers, but also for the entire Columbus community.
