I recently installed Ring standalone at a client's house. We did not try and integrate it with anything on this project. The camera is decent at its price point. The intercom works well enough.

Ironically the guys rang the doorbell at this project, I forgot I had the app on my phone and it went off while in a meeting. So I fired it up and messed with my tech for a few minutes. I could tell who he was and understand him. He could understand me, but could not recognize my voice. If it was someone I did not know it would be tough to recognize them.
