How Do You Know Your Camera Contains The Components Claimed On The Spec Sheet?

I have heard some reports lately of lower-cost cameras swapping out key components like sensors or encoder chips for alternative/cheaper versions when supplies are tight.

Has anyone had this happen to them, or suspect it of happening? How do you know that the camera you are selling/installing today is meeting the same specs as the one you tested 12 months ago?
