I’d like to buy the Kami Outdoor camera as it has the feature called “Smart AI Human Detection”.
But I do not want to buy Kami Cloud due to extra costs. Is it possible to connect Kami cameras to Yi Home cloud? And if not today, will it be possible in near future?
Hi @timow welcome to the forum! 
You can mix and match YI and Kami Home Cameras using your current cloud subscription. You can also use both camera brands within the same phone App. The YI Home App and Kami Home App are compatible with both YI and Kami products.
