Not sure about the specifics, but this looks like a bluetooth microphone whose receiver connects to Sony cameras via the multi interface hotshoe.
It claims a 600' maximum range.
Seems like maybe it can only use one channel and the transmitter probably doesn't record?
Probably no locking connector for the mic input, either.
And perhaps the receiver has an internal mic as well?
