Excellent questions, @Howdoesitwork. At this time the Blink Cameras do not integrate with Ring and is not supported through the app. Keep an eye on our integrations boards in the Community, as neighbours will often share what they’ve accomplished with these integrations.
You’ve got a great use case for your inquiry about the shortcuts! The new shortcuts feature in the Ring app are dedicated to only your Ring or Works With Ring devices and history. As we value our neighbors’ feedback, we’ve created a Feature Request board. Feel free to add this and any future feature requests there. This will help us to organize and share your requests with our teams here, as well as allow other neighbors to comment and add interest, all in one place.
