CONTACT US Only been using ADS for a little over a month now, but every single interaction with the company is extremely professional. They fix issues right away and are very responsive to any inquiries. Their techs are friendly and helpful, as well. Adam Motz We have had ADS protect our home for over 14 years. They are far superior to the two companies that we had before we moved to the Chicago suburbs. They have always contacted us in less than a minute when we have accidentally set off our alarm. Recently they contacted us to advise that one of our batteries was weak and needed replacement as they have done a couple of times before. The technician, Jose arrived as promised and quickly diagnosed what the real problem. He ended up replacing both of batteries in our 2 controllers and replaced one of the controllers completely as an upgrade. He was very courteous and cleaned up completely before leaving. Our radio backup has been great when we have had power failures and phone line problems. Tom Kloempken We have had ADS protect our home for over 14 years.

In that time we have had maybe a dozen alarms (all accidental, thankfully) and their response has always been perfect! Their service is excellent. They do all of the work themselves, no subcontractors to worry about. We have always been more than satisfied and recommend this company to anyone contemplating installing a full service alarm system. Colin C.
