LAPOLE-Dash POV?BMW M3 Competition RWD, Shanghai F1 Circuit. 2:29.66.

iPhone mounted on LAPOLE-Dash mount, utilizing Dragy Lap's double cam recording function. The iPhone screen worked as a lap time display, and the front and rear lenses recorded simultaneously. The two footages can be replayed in the app, and rendered as a PiP video. This might be the most reliable, economic, simple and easy onboard recording solution!
