The new GoPro Hero5 Black and Hero5 Session have the ability to respond to voice commands, so the GoPro 'Remo' camera remotes are intended to help expand this functionality.
If your GoPro camera is out of hearing distance, the GoPro 'Remo' enables users to speak to the device to perform commands in order to help expand the capabilities of the action camera.
The GoPro 'Remo' is designed to be clipped onto your clothing or worn on your wrist and features a waterproof rating for up to 16-feet. While you won't be able to speak to it under water, the GoPro 'Remo' camera remotes are also outfitted with a simple record button that can be physically used if voice control isn't possible or not wanted.
