Owners of GoPro action cameras can now live-stream video to the world on Periscope.
The small cameras are a favorite with adventure seekers and videographers of all kinds.
To make it work with Periscope, a "GoPro Hero 4" camera first links to an iPhone through WiFi.
The newest version of the Periscope app now allows users to select to GoPro signal and stream it live.
Periscope is owned by Twitter and has about 10 million users.
