Has had big problems with mine GoPRO 3 black and 4 silver camera,have had only trouble with them.
Camera turns on and off all the time and Camera Freezes Up.
Sow yesterday i buy the new GoPRo 5 black, but camera can not output video from usb,only from hdmi.
If you are going to have video out you need a hdmi converter,shall return it to the store.
So now I’m tired of everything that matters GoPRO,Is not worth the money,in my opinion.
Have discovered a camera called FOXEER Box 4K CMOS.
This camera has USB video out and you can supply camera with 5 volt.
Looks pretty good,Costs $ 170
I have ordered one from http://www.foxeer.com
