What doorbell features are only available with protect plan? (UK)

I’ve just bought the ring view cam. Can someone confirm what specific features only work with a protect plan? The ring website is quite generic and doesn’t go to the detail of features. For example:

I assume WILL work regardless of whether I pay for protect plan:

  • Knock detection
  • People only mode
  • Motion zones
  • Motion sensitivity

I assume will NOT work as rely on saving images/videos in cloud:

  • Snapshop capture
  • Event history

Thanks!

Update to this based on chat with ring support - they say people only mode requires a plan, but the other factors don’t. So…

  • Knock detection
  • Motion zones
  • Motion sensitivity
