FBCAnna church Office

They reworked our code system. Did a wonderful job with everything. We are happy with their work every time we call them.

Response from the owner: Thank you for taking the time to leave a review!

Randy Henderson

Once again the technician asked the right questions and sorted the problem out. I was unable to verify which zone each sensor was on, but he tracked it down and determined that the problem wasn't where we thought it was. He replaced the bad sensor and checked the others. And on the day I called. Thanks again, Security Alarm.

Curt W. Ferguson, P.C.

Quick replies and great attention to detail! Knowledgeable and friendly staff! Got us taken care of quickly!

Robert Marley

Troy and Larry showed up in a timely manner. They were courteous, knowledgeable and professional. They fixed my problem in minimal time.

Response from the owner: Thank You Robert!

Tony Wielt

Have worked with SAC for over 15 years now and recently made a much needed upgrade. Each interaction that I have had with them, from the Office Staff to the Sales Staff to the Installers, was professional and positive. They worked around my customers during installation and was minimal interruption to my business. Plus - they are locally owned and operated. That means a lot to work with other business owners like us.

Larry Bemesderfer

Jeff was here yesterday and found the problem with both cameras and even had to work in the rain to get them replaced and up and running. Thanks

Jim H

Everything you could hope for. There was no attempt to sell us something we did not need. When a minor problem occurred they were there to take care of it. Great friendly people.

The technicians (Curtis and Jeff) arrived as scheduled, had the installation diagrams as discussed with Larry during the sales presentation and immediately began working on the planned installation. These gents came prepared with proper tooling, equipment and most impressive was a strong desire to satisfy the customer. The install was timely, they ensured their quality of work was satisfactory and cleaned up their work areas after the system functionality was verified. Great technicians!

Response from the owner: Gene, thank you so much for taking the time to leave us a review! We are so thankful for our techs and the amazing work and customer care that they give.

I called Security Alarm to check on cameras for outside since we had used them in our Ag business for years. The process to get lined up was simple and Larry was very thorough in explaining everything. They were out in just a few days to install them. Both guys were very friendly and professional. It didn't take long to install and I know they probably had wiring issues to deal with. They did a great job and the cameras show exactly where I wanted them. I am very pleased with the service and products installed.Thanks!

Response from the owner: Thank you for taking the time to leave a review Cindy! We are so happy that you had a great experience with us and that you are pleased with the product. If either of those things ever change, please let us know!
