I don't think we can get these cameras in the UK, but there are a few that are either copies or the same thing, see https://www.amazon.co.uk/gp/product/B07 ... 616030b420 for example.

Xiaomi hardware ? Different firmware ? I'm about to sell my house, and I may just bug the whole place

I see a lot of copies or clones of these on Ali Express, Banggood, Deal Extreme, and other Chinese shop & ship places. Shouldn't be too hard to find.

As for the differences, I don't know the specifics but there are after-market FW packs available for them, like these:
