I want to translate the camera by 2 inches, but found that POV does not have unit declarations. Are there any default settings to declare 1=? If there is none, then how can I translate by 2 inches?

The units in POVRay are arbitrary. If you want to model something in inches, just assume that all coordinates in inches (including the camera). Then translating by 2 means translating by 2 inches. You just need to be consistent that all distances are using the same units. Something that's two feet away has to be entered as 24 if you're assuming that 1 means an inch. If you want to do feet to inches conversions, you can create macros to do it.
