Excellent company and great service after the sale! Top notch! I wanted to update my review. I had CSS come out and do some tune ups and add a few things. Always great service! Still providing great service 9 years later! CSS is the best company in Middle TN period!

We love our CSS alarm system! We have set ours off accidentally several times since we moved into our new house and they are always so responsive! It's great to know they are there if we need them! Our siren is so loud there is no way that it will be missed! The installer and everyone we have interacted with on the phone with have been so polite and helpful!

CSS Alarms is a locally owned Nashville company. We signed up for their "cameras for life" program. It gives us peace of mind knowing that CSS will replace cameras and offer upgrades when available. I can't say enough good things about their customer service. They are prompt, professional, and honestly go to great lengths to get to their customers individual needs and situations.

CSS Alarms was awesome to work with! They didn't bombard us with tons of paperwork and overall process was fast and easy. The installers were professional, friendly & knowledgeable. If we have any questions about the equipment, they respond quickly and provide detailed instructions. Go with the folks at CSS, you won't be sorry.

The Cameras For Life Program was a perfect solution for our business. The install was done by true professionals. They had them up and recording in one afternoon. 3 days later, a neighboring business had some vandalism, and we were able to help local detectives with the footage from these cameras. Thanks CSS.

I have been a CSS customer for 18 years. Recently, I had them install several cameras on my property. Justin met me at home and went over the process step by step, and was able to show the resolution of the cameras. They are excellent, and I now I have full surveillance of my home and property. The entire process went fine. The installers and all involved are very personable and professional. I would give them 10 stars if I could

Extremely satisfied with the service provided by CSS Alarms. The owner did a personal review of the current set up and provided recommendations. The technician did an excellent job with the installation, and showing us how the system works. Everyone in the office that we dealt with over the phone have been responsive and helpful. Everyone was professional and friendly. Very happy with the decision to work with CSS Alarms.

The CSS Team has been with us every step of the way the past 5 years after we built our home. They installed our Sonos home speakers, our alarm system, and now our home video monitoring set-up. From Justin (President), to Katy (Operations Manager), and all the service / install people - absolutely top notch, could not ask for anything more. The 4k Video monitoring system was a much easier install than I thought, and has given my family peace of mind. Thank you CSS!

I have been very pleased with the professionalism and capabilities of CSS. Their employees present themselves well and I am happy to have them in my home. They had more products/services than I needed at the time but never pressured me to purchase more than what was necessary.
