There are only a very limited amount of camera’s that have custom firmware (I only know of two Xiaomi camera’s), and none of the ones you mention seem to have one (but you probably found that out already by Googling before you asked your question here).
You already know that the K5 offers ONVIF support, which is local (however, I don’t know if that’s similar to Homey’s “local”, where it still needs cloud access occasionally).
