We are unique in that we live outside of the London area. As a matter of fact, we live in another province. That's what makes the personal attention and service we receive from AlarmTech so remarkable and exceptional. One of the best small businesses we've had the pleasure of dealing with.

I have Security ONE at my house, the service is amazing, the people are great and the system itself is awesome. I highly recommend Security ONE to everyone looking for Security. They're also a local company so that's a bonus!!

I had Ian and his guys install 7 cameras throughout our warehouse and parking lots and they were great to deal with. They were able to do the install over a whole day on the weekend and got it up and running that day.Overall it was an easy and great experience. I would recommend using IRS Security!
