Donovan quoted me an estimate and after agreeing, we scheduled a visit the next day. He showed up on time and installed our Samsung Q910B sound bar to be used with Apple 4k and our Sony A90J TV. It sounds great. Donovan knows what he is doing. There was good communication and no surprises. The whole process was handled professionally and to our liking.

While I can't rate the quality of Sonitrol active service/response, I can rate their customer…read moreservice as poor. When I moved into a new house it had their system installed and the prior owner claimed to not know the system master code. The system randomly chirps and sometimes alarms inside the house. All we can do is silence the alarm each time, but nothing else. Sonitrol customer service said I would have to set up active service with them, including a monthly monitoring contract, for them to reset the code. I explained I didn't want a monthly service, just the ability to turn the system off. I was willing to pay a one-time fee for them to come out to reset it, but was told they couldn't help me with that unless I established monthly service. So I have a system in my house that I cannot turn off and Sonitrol wants to hold me hostage until I enter into a long-term contract with them. Ridiculous and terrible service!

If I could give them zero stars I would. They run this business with zero integrity…read more Unfortunately, three times one of my partners has selected them to provide security for our business, and each instance has been one that I've deeply regretted. They are more than happy to sell you a system but should you have any issues with it or need to cancel, forget about finding a willing partner to work through it with you. Some of the worst customer service I've experienced in twenty years of doing business in Charleston.

Installation was scheduled for the very next day, their team showed up right on time, got everything done efficiently, and they even gave me a full walkthrough of every feature. They made it super easy to understand how to access my system and monitoring status right from my phone--a huge plus. I looked at national competitors and Sentinel Alarm gave me a really good rate that was fair which is something I value highly as well as their ability to help me and my family feel safe! . Highly recommend Sentinel Alarm Company for anyone looking for reliable, affordable, and professional fire or burglar alarm systems!
