it is the version 2013, 2014 Version GoPro Smart Remote long-range remote control for GoPro HERO4, HERO3 + HERO3 and has indeed in all three button (the button in addition allows for directly setting the gopro used)
Attention still uses only the remote wifi, and therefore demand that it is also enabled on the gopro, and suddenly the camera will empty the battery much faster.
why the wifi? as it runs away and the remote control can run up to 50 GoPro ... then it was the time to put wifi everywhere ... now is the bluetooth, the bluetooth live !!!!
