One variation of a method for recording accidents includes: in a first mode, capturing a second video frame at a second time, storing the second video frame with a first sequence of video frames, captured over a buffer duration, in local memory in the helmet, removing a first video frame captured outside of the buffer duration from local memory, and rendering a subregion of the second video frame on a display arranged within the helmet in response to detection of an accident involving the helmet, transitioning from the first mode into a second mode in the second mode, capturing a second sequence of video frames, and storing the second sequence of video frames exceeding the buffer duration in local memory and generating a video file from the first sequence of video frames and the second sequence of video frames stored in local memory.
