When I thought about where to mount mine it went beneath the seat due to having no desire to use it or have the distraction while riding. At 1080p and thru the windshield, the video quality is great for license plates and traffic incidents but not good enough for home videos. If you want an event recorder it seems to me an external button was available. Been two years so I may wrong on the button.
In any event, I've only wanted info off the video a couple of times and with a 64 chip in the thing it records for many hours. Plenty of time that evening to pull the chip and copy it to the laptop.
