Even for adults, there’s separate restrictions on publishing the video for commercial purposes than for recording it in the first place. I don’t think Ring’s TOS can protect them from claims from the people who aren’t Ring customers themselves.

A science outreach job I had (in Australia) took special care to ask for consent for photos for their media page. If no consent forms were received, then they got a fluoro yellow sticker to wear so that photos were not taken. I was told that the reason for this is that some children are hidden from their bio-parents because said parents were bad people. We didn't want to risk the stalkers/bad parents from finding vulnerable children so no photos without a consent form.

I think this is the implication that should be considered in this situation and I think this makes Ring either very stupid or very greedy (or both).

...in the US.

In other places the laws can be different, especially if the camera hasn't been registered.
