  The thread may be old, but today's action camera are very freindly in temrs of operating them. One of the latest release (https://www.yitechnology.com/yi-4k-plus-action-camera) has some amazing features.

  Nice find. The specs for the YI 4K+ seem to match the latest GoPro. But the price undercuts GoPro substantially. I wonder if the camera lives up to the comparison or if it's just an inexpensive knock-off. Have you done a direct comparison? Low Light sensitivity? Image quality?Some cameras (and software) like to do dumb things to the videos which make them useless for physics analysis. The drop frames, they blur fast-moving details.If you get one of these, I'd be happy to hear about your experience.
