For over twenty-five years, ADSi has offered peace of mind to our family, friends and neighbors. Unlike large national companies, we live and work in your community. Our local staff of highly qualified and NICET certified technicians are proud to serve our local hometowns of Mountain Home and Harrison as well as southern Missouri and most of Arkansas. Providing fast, friendly and personal service to our customers is what sets us apart. We offer security systems and fire systems for both home and commercial, as well as Medical Alert Systems, Video and Camera Surveillance, Central Vacuum Systems, Computer Networking along with Intercom and Sound Systems.

Our goal is not to make a deal; but instead make a difference in your life. Our Build Your Own System is different; and a ground breaking approach in the security industry. Unlike our competitors that offer pre-packaged systems; we allow our valued customer, the freedom to personally design a system that fits today's needs and budget. Better yet, our lease program offers a full repair or replacement service agreement and you will never be left with yesterdays technology. System upgrades with loyalty credit are available at little or no cost to you. To truly see what makes ADSi different, contact us today!
