Anyone have played with one of these expensive thermal  cameras?

We will have an update this year - we've been comparing a high end  camera 
with a high end calibration system against a 'relatively' inexpensive  hand 
held.
 
Either has to be used when ambient temperatures are used - best at  night.  
During day, solar radiation hitting outside of hive obscures  temperature 
of bee population inside.
 
One can get misreads from combs full of honey.
