When we signed the Vivint agreement we didn't select the premium service. That service costs an extra $10 per month and covers all of your equipment and the cost of the service calls. Our Vivint salesman told us all of our equipment was covered by warranty for the entire length of the contract 60 months. What he didn't tell us was that it would cost $49 to have a technician come to our house to replace the broken equipment. I will admit that it is my fault for skimming the the fine print, and I mean almost unreadable fine print, on the back of the Vivint contract. It does say there that you must have the Vivint premium service package to waive the service fee. Our new Vivint doorbell camera has the same connection issues. I once again called Vivint and was told that we would need to have a repeater installed between the camera and the panel. The panel shows that the signal strength on the camera is above 90%. Vivint said that they will charge another $49 service call fee to have a repeater installed. I argued that the system was not installed properly if we needed a repeater, but they will not waive the fee.
