Ask HN: AI Baby monitoring state of the art?

I remember many years ago seeing a demo from an algorithm from MIT which took a simple raw video of a baby and, with clever video manipulation, could so clearly augment changes between frames that it made it even trivial for the naked eye to see the baby's pulse, or breathing rate (and it had accompanying demos which showed that data simply from the inferred image).

My extended family suffered an incredible tragedy many years ago after a cousin briefly asfixiated during sleep, causing irreversible brain damage, and it has constantly nagged me that surely some kind of baby monitoring leveraging that tech could have prevented it. As a newly-expectant father, I am turning my attention now to these questions for my own child, but as hard as I've looked, it seems to me that the technology behind baby monitoring hasn't strayed too far from what we've grown accustomed to for a long time, save for just improvements in ergonomics and things of the sort. Curious if anyone was aware of some examples of what today would be the most extensive types of monitors available, eyeing especially any leveraging of "tech" to infer things like oxigenation, pulse, etc.
