What Our Customers Are Saying

Excellent
4.9
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.
The gentleman that was here--I'm sorry I don't remember his name--did an excellent job researching and troubleshooting our problem. He was humming a happy tune all during his time here. We found a couple of discrepancies in the wiring which he documented, and then he replaced a motion sensor which seemed to be causing our problem. Asked me to call you if we still have more problems. Thanks.
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 cannot say enough good things about Security Alarm. Their office staff are very professional and helpful, wonderful sales staff who explain all options thoroughly and without bias. And their installers are outstanding, very knowledgeable and care about the customer, ensuring all questions are answered before they leave the job. I’m so glad we went with this company, and most of all, I feel our home is now safe and secure!!
Security Alarm responds quickly to our needs as soon as we call. Their technicians are highly skilled and the customer service team is exemplary.
The installation team did a wonderful job upgrading our system. They were friendly, efficient and very knowledgeable. We have been extremely happy with our Security Alarm service for many years now and look forward to many more.
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
The entire experience was great. Meeting with salesperson Ryan C. who didn’t try to sell us things we didn’t need. The installation crew who cleaned up as they went along and answerd all the questions about operating the system. Top notch all around.

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!

we needed to change around a camera and a camera needed to be replaced. All the work was done perfectly and service was done in record time with no problems. We always get great service with Security Alarm Company.
Response from the owner: Thank you for taking the time to leave a review!
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!
We have been trouble shooting several trouble alarms and Security Alarm has been very responsive and willing to help in what ever way they can. After the most recent service, the technician was great at telling exactly what he did and next steps if this does not solve the problem.
Response from the owner: Thank you for taking the time to leave a review, Steve! We are so thankful for our technicians and the work they do!
Security Alarm has a great team and has always taken great care of my business and home. Would highly recommend!
