Some tips; the zoom and picture quality of an MV32 is no where near as good as an MV12. So I use MV32 to be able to track where people are moving or where things are moving around or to get a general impression of how things are moving in the environment, and MV12's to get specific details (like a clear picture of someone's face).
Often if you zoom in on someone's face with an MV32 it just isn't clear enough to be usable for an "identity" photo.
