Satisfied Customers..

“I was contacted quickly by Jim, the owner. We had an alarm system, but were interested in something with wi-fi capability so we could monitor and control the system remotely. He described the options, and I was happy with his suggestions and the cost. He did the installation within a couple of days, and everything went perfect. In the process of testing some of our original equipment, Jim discovered that two of our critical zones weren’t working at all. Jim’s cost on the monitoring was also a significant savings over what our previous alarm company was proposing. I would highly recommend Jim.”
