Ive been with them for 12 years. Unfortunately, I was robbed and it lead me to needing the alarm. It was the best decision. I do my part and use it religiously, every time I leave, no matter how short the trip. Every night I sleep great knowing the house is secure, not worried about any little noise. I love that the call center is local and quick to call if my alarm goes off. I have had a few service calls over the years, always great people, nice and professional. Definitely recommend working with this local company night and day from the lower quality service and responsiveness of some

You don't want a dishonest, sketchy company running your alarm system.
Sentry Alarm bought out our local alarm company. We were customers for 8 years. We had a faulty sensor and had a repair man who fixed it. Soon after we moved and left a voicemail but didn't get a response. Then we got charged for another 6 months of service without any bill forwarded to us, so when we called to resolve that, they said that when that serviceman came out we had signed another 5 year contract with them. We NEVER would have signed that, so it was forged or snuck into a document dishonestly. They want us to pay
