What Our Customers Are Saying:

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 guys were so nice and explained everything to me. They were here at the time I was told. Can't say enough good things about them!

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!

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!
