Actually, there are four articles from Dec 2016 through summer 2916 on IR cameras.  It's fairly easy to spot queenless colonies - there's no tight cluster with a hot center - rather a diffuse temperature pattern across the frames.


P.S.  An IR camera clearly shows the disadvantage of top bar hives in terms of temperature control - bees evolved mostly in vertical shafts like hollow trees and they use that structure to set up convection currents.
