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. Vivint said if we would have needed the repeater within 120 days they would have replaced it for free, but we are outside of that timeframe. During that 120 day timeframe Vivint customer service was having us reset the camera. I really like this doorbell camera and how it integrates with my ADT system. Some notes on installation: 1 My mounting plate was slightly different than the one shown here as it had three slots for mounting screws as opposed to the two shown here. I used three screws to mount the plate. 2 I found routing the two existing doorbell wires to the connecting screws a little tricky. There seemed to be a couple ridges in the way of getting the wires into position to align with the two small slots in the rubber plug that environmentally seals off the electrical connections. It took some patience to get things aligned for a good seal. 3 I mounted the plate snugly to my wooden door frame and then followed all the instructions to let the camera update firmware, register it to my system and then snap it into place on the mounting plate.
