10 months agoYou don’t film two minutes of realtime with a high speed camera. It would take years to play back.
You record on a loop (constantly erasing a few seconds of realtime) on the internal RAM, and when you trigger the camera, you save a little bit of footage before and after the event. This can still be hours of footage when played back at 30 fps. You only need an SSD or regular old ethernet to download the saved footage.
The disposable ones also use rechargeable batteries because they’re cheap and can deliver the power required.
Discarded vapes are actually a pretty good source for free lithium batteries for hobbyists.
