Today, 11/12/25, Guardian technician John Fay came to my home to determine why my new wireless doorbell could not connect to my WiFi system. The problem started 11/6/25, when I recharged the battery for the first time and it did not reconnect to the WiFi system. I called Guardian Alarm technical support and worked with Andre for 30 minutes but the doorbell could not connect. He scheduled first available appointment for 11/12, noon to 4 pm window. John Fay called ahead and arrived at 2:25 as estimated. John updated the firmware and then connected the doorbell with no problem. He was professional and efficient, patiently answered my questions and provided tips on setting the doorbell for best use in my location. I will be asking for John Fay if I need any service calls in the future. I am pleased with service and quality of equipment Guardian Alarm provides.
