I do NOT have a touch screen. My intent was to use the cameras through the xfinity home app. I have 2 XCAMs and 2 XW3 wireless adapters. My router / modem is a Cisco XB3. When I try to pair through the xfinity home app, I follow all of the instructions, but when trying to pair with the power adapter, it says "we're having trouble detecting your camera." It then has me try to add manually, but stops and says "your wireless gateway is not supported."
I have had numerous discussions with support where they have told me that everything should be compatible and working, and even swapped out my gateway this afternoon to no avail.
In doing some research on my own I figured out that I need the touch screen to pair the XCAM with xfinity home. I am not sure why the 4 or 5 customer service reps I spoke with told me it was compatible and should work when it is not but hopefully this helps someone else.
