They are fine, but it doesn't help much when the alarm goes off and nobody shows for 45 minutes, like there's really no point to the alarm

Great company to work with. I have had Sentry for 4 years and they have treated me well. As part of a home remodel their service tech (nick) came out and relocated my panel. Nick did a great job, very thorough, professional, respectful, and cleaned up afterwards better than what he started with. I highly recommend Sentry if you are looking for a security system.

I only gave a one star because there is no way to give 0 stars. Terrible terrible terrible. Avoid at all costs. I agree with what the other 1 star reviewers are saying. Terrible service and fine print contracts that you can't get out of, unless if you pay them for no service rendered. A terrible, greedy company that should have a class action law suit brought against them for the way that they do business.

Sentry Systems customer service and systems are way ahead of the other competitors. We moved to them after ADT made a massive mistake which cost my Office Condo association over $100,000. Will not work with ADT again and appreciate the opportunity to work with Sentry Systems. Thank you

Excellent service! Wonderful company to work with. Great people in sales - technicians are very knowledgeable - office staff are super helpful! Working with them doing a complete building update was a pleasure. Big thanks to everyone at Sentry Systems and keep up the excellent work!

The monitoring service is fine. The contracts, making changes and finally cancelling was miserable. I left a negative review on the BBB site as well. I will not be doing business with Sentry Systems in the future and would highly recommend that you look at other alternatives who will provide service. Think cable company/xm radio/AT&T service levels. All of which have shown up on the Wall of Shame for customer service. UPDATE 7/29 Mr. Olinger decided to contact me numerous times regarding my review.

It got to the point of harassment. I do not have patience for bad service and had many difficulties with his organization, including at the time of renewal when I requested a copy of the contract, was informed that it automatically renewed at newer terms, which were higher and I could not cancel for another three years. (Never received a copy of the contract when requested.) I firmly stand behind my original review, am not willing to change it and have told him to never contact me again regarding business or the review.
