Yes - it's exactly that: an adaptation of pix_movement that lets you specify an area to analyze.  That way you can use several instances to create multiple regions for triggering different events.  I haven't looked at this in two years!  I'll take a look at the helpfile and see what's missing/unclear.

what's the difference between that, and using [pix_crop] and [pix_movement] with [pix_separator] ?

Please correct me if I'm wrong, 
Doesn't having these as externals instead of abstractions, make it significantly faster/efficient?
particularly if you have many of them?

best,
