Help me understand the difference between Face Detection and Face Recognition

[Bill Gates]

Hello! I was looking at the specs of various cameras from Dahua and Hikvision. Many of them offer Face Detection, but I read somewhere that's more of a gimmick. Is Face Detection worth at all? What is the difference between face recognition? And are hikvision and dahua face recognition/detection the same or is one better than the other?

FD= I see a face and identify it as such (vs a bird or a leg or a car). I dont store it or compare it to anything
FR= I see that face and copy it into my internal database, check my database to see if I recognize it from before, and can use rules and alerts to do things about it
