I don't think we've added support for Philio yet. We've been a bit slow at getting some things that we have working, but as we often only have one sample of things, I can't test things here
In what way was the camera proprietary? Any Wi-Fi or Ethernet based camera should work with the Almond+, we just don't have any kind of integration in our apps/UI's for cameras at this point in time.
