Donny and Mike were super. My system is older and they took extra steps to find info on the system and reset it. Gave me perfect instructions and the system is working great. I have been a customer for over 20 years and remain a very satisfied customer. Linda Tunnell

We have been with Sentinel Alarm Company for many, many years. We couldn't be happier with the monitoring side and the service side of the business. Excellent Company and Service.

Mike Spannagel from Sentinel Alarm came out and rewired a window for us, then out of courtesy checked all the windows. He’s very professional and pleasant. Did a great job!

Sentinel has protected my home for years. Intrusion, smoke, fire and carbon monoxide. They just upgraded my cellular unit, made our system controlled with our cell phones and put in cameras at our front door and rear entry garage. We had a problem with the garage and Chuck stayed until almost 7 on a Friday evening to make sure it was up and running correctly. The cameras are HD, color and analytical, as well as being set for a field of recognition. No unwanted alerts when a car drives by or a cat walks across our driveway. We can set it to recognize a person, vehicle or animal in a defined area. When the safety of your home s at stake, you want the best. And Sentinel The Alarm company is the best.

Robert is awesome. He moved a sensor over three inches to accommodate construction. He was fast and efficient. As a whole, Sentinel is a great company. I appreciate their attention to detail and great customer service.

Sentinel is one of the best companies I have ever worked with. They have a customer-first mindset, which is always appreciated. Everyone is professional, knowledgeable and a pleasure to work with. Robert Adsit is terrific. He came in, recognized the problem immediately and fixed the battery issue within minutes. I had a couple of questions for him, which he stayed and answered. Sentinel goes above and beyond. Thank you.
