I could have endless fun with a swarm of those

Pretty early in the vid (0:05 or so) they show the upper half of the room. Running along it is a bunch of sensor equipment.
My assumption is they are programmed to do their little dance, and are given the signals to do so through the field given by the equipment.
Exactly my guess..
So pretty much they are useless outside.
I can see however a good application to use these, in conferences, meetings, concerts, shows, debates, or any place indoors where a lot of people will meet for some reason and have them carrying cameras in a tactical movement to closely cover the entire space with "eyes" against supposed terrorist attacks or any other threats.
They could also be used in large public spaces like airports where they fly through a tactical path in order to cover the entire airport.
