  Hello. I had the pleasure of dealing with Cathy at Alarm Systems in Belleville, Ontario. Cathy is very knowledgeable, and she is a kind and caring person. She answered all of my questions without hesitation and understood my particular needs as a customer. She always got back to me promptly, and she is the kind of customer care person every company needs regardless of her actual title at Alarm Systems. In her own quiet way, she keeps the business running. Darlene.

  Aneesh Thomas arrived at our home well within the time given and proceeded to install our new security system. Aneesh was professional, knowledgeable and did an amazing job setting everything up. He was very thorough while explaining how the system worked and very patient while answering the questions we had. It was an absolute pleasure dealing with Aneesh.

  Alarm systems was so great! They came in a timely manner and set everything up quickly and efficiently. They gave me a thorough run through and took their time explaining everything. They even did all the loud testing outside or in the basement while my baby was napping so they wouldn’t wake her up! Very happy with the service and the set up.

  I highly recommend this alarm system. Damian is very professional, knowledgeable, and never pushy. He provides helpful advice, clear recommendations, and a proper quote, then gives you time to think and decide. He will not pressure you to use their service. Before, during, and after the installation, the team was knowledgeable and professional.
