> A camera take a picture of that wall every millisecond
That makes the camera work at at least 1000 fps, and it needs to take picture of 100 lava lamps. From what I've seen from hight FPS cameras in science channel shows, those tend to work well for a small target area with bright light. Can anyone from cloudflare talk about what kind of camera or cameras are used for this?
They are not trying to record high speed video. A camera may take a picture every millisecond, but it doesn't have to be one camera. They could be using multiple cameras interleaved in time...
