This sentence is a bit awkward. How about this:

location: The mount location of a device (typically an image sensor or a flash LED)
expressed as a position relative to the usage orientation of the system where the
device is installed on.

system For -> system. For

Actually, I'd move the For to the next line.

I think you mean 'but is' instead of 'or is'.
