Any good quality rear view mirror dash cams?

[venezian]

I've seen ads on IG for a few brands and when I research, nearly all of them do not have technical specs disclosed on their website.

Are there any good quality mirror cameras out there?

I like the idea of having a true 4K 2-ch frame less rear view mirror that can utilize existing power.

Have you looked at the 70mai S500? That's the only rear-view mirror cam solution that I've seen so far, that utilises the Sony Starvis 2 IMX675 sensor (not 4k but it's the latest you're going to get really).

Others that claim to be 4k aren't actually. Lot of Wolfbox cameras going out there that use the now five-year-old Sony IMX335 sensor that has been interpolated to 4k (i.e. blown-up to say it's 4k, but it can only really capture 2K max).
