Dash Cams vary in weight and size and therefore for DE Events double-sided tape is not an acceptable mounting method. Rigid mounting only is allowed. The concern is that if the camera breaks loose from its mounting, it will at the very least be a distraction and worst case could hit the driver or instructor causing injury.
One thing to be aware of if wiring the camera to be ON at all times, is that this will increase the ‘parked’ drain on your battery. Make sure you use a solar charger plugged into the accessory socket or you might one day find the battery dead with no way to open the electric released frunk on your Boxster to access the battery 🙁 I know the early cars had this potential issue, not sure about the later models.
