EMG-Connectivity have developed a system which remote triggers multiple GoPros in a single venue to shoot at 200fps for a selected time period which recovers the footage within 5-10 seconds to make available for playout. 

This system was used very successfully at the recent European Championships in Munich on the BMX and Athletics venues. 

Four GoPros were placed in discreet locations and footage was triggered and turned around for playout immediately. 

As well as playout to EVS , the EMG-C server stores all of the clips ready for later playback or archiving for production download with our web media interface. 

Please have a look at the setup and the output of these cameras at the recent European Championships in Munich:
