What Our Customers Are Saying

Excellent

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!
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.
Quick replies and great attention to detail! Knowledgeable and friendly staff! Got us taken care of quickly!
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!
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.
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
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.
So pleased with the security system at UcamP Express RV Park, it has afforded me the freedom to do life, but yet be able to keep up-to-date on everything at the park. Customer service is top notch at Security Alarm of Salem, IL.
We have had Security Alarm for several years. Unfortunately, we have accidentally forgotten on occasion the alarm was set when we opened a door. Within seconds we would get a call making sure everything was okay.A couple times we had to have a technician come out to our house for a minor problem. The problems were resolved quickly and professional.We highly recommend Security Alarm for your home and business security.
Response from the owner: Thank you Vicki for taking the time to leave a review!

Thank you Watson for your prompt attention to our issue.
Our technician was the the Salem office. He was very nice, professional, and knowledgeable. I'm bad with names, but I think him name was Troy. I hope his boss acknowledges his good work.
Security Alarm is one of the best companies I have ever dealt with. As a landlord I have used so many companies for so many different things but not all give amazing service and give you a product beyond your expectations. It's always a pleasure doing business with you guys. Thank you for the wonderful service over the years.
We had a minor issue with our buzzer system for the entry door and Josh responded to our email within a few hours. An employee was at our office the next day and had the problem fixed within 30 minutes. We love the system they installed and would highly recommend Security Alarm. Mark Miller, Marion County Supervisor of Assessments

I have been dealing with Lowitt Alarms Security Alarms since 1997, I an very satisfied with there service, I had a problem 4/5/24, I could not shut off the alarm, after calling Lowitt and following directions I was not able to shut off the alarm, I was told that the next appointment for repair would be tomorrow, I explained the we are seniors and please see what you can do, Linda, was able to made some adjustments and a repair person came to our home at 4Pm and put a new battery and radio, I highly recommend Lowitt Alarms to any one who is shopping for a Security System

Response from the owner: Thank you Vicki!
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: Thank you, Russ, for taking the time to leave us a review! We SO appreciate it!
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!
Security Alarm has a great team and has always taken great care of my business and home. Would highly recommend!

“Staff performance: Just would like to report I have had excellent experiences with all your staff. They all have been very professional, courteous and personable. The one stand out is Watson. He has demonstrated a great deal of patience and genuine willingness to give his best to resolve any problems I have brought to him. His technical knowledge and ability to troubleshoot is outstanding. You have a solid team at Security Alarm and as a customer of yours I wanted you to know I appreciate it.”
We have several cameras from Security Alarm. Our favorite is the thermal imaging camera. It is great for watching pastures at night.
