Hi, I really would love to buy a Tapo 4K resolution cam (or close to it). I've looked and looked and would I be correct in saying that the likes of the C520WS is about the highest resolution camera at 2560*1440? 

Does any insider know if such (4k) cameras are in development/in production?

Or if I'm missing something in my Amazon searches, please enlighten me as to model numbers :-)

Thanks
