Just come across a company called Zobi who say "We created Zobi Home Intelligence to make it easy for anyone to detect and prevent cybercrime in their home."
From what I can tell, the model is that they'll include their AI in compatible devices; they're promoting a home appliance called Hedgehog that retails for £99/$135 (I think these are introductory prices and it will cost more once launched properly?). I'm pretty sure I saw somewhere on the website that it said there was a subscription after the first year, but that seems to have disappeared and now the product pages clearly say NO subscription fees.
Links below... Would be interested to see what you guys make of it. And no... I don't work for them!
