So I had an Arlo camera but I could not set sensitivity low enough to stop annoyance notices so I sent it back and got the ring 2 door bell. It works much better except every so often it loses communication with our phones, this will last for a few hrs. then everything will be fine for several days then it happens again. Anyone else having this problem? I have a friend who works for a CCTV Co. and he said it is not a modem or router problem as far he can tell. Any thoughts?
