I have two of those INNOVV K2 systems on my bike. Front, Rear, Left, Right .... basically you connect to them with with a a WIFI connection to your phone. Then you use their app to connect to the controller via ID and password to view history or configure the options. They have a security feature that will start recording if triggered by bump or shake, but mine are mounted in tourpak and that feature is not as sensitive as i would like. I have them connected to switches on the dash so they can be deactivated when riding.
Frankly, it is not all that i would have wanted due to the hassle of connecting and searching for the one of MANY video files you may be looking for.
I have seen other dash cams that seem like they would work better and have the option to review history with less difficulty.
If you do choose to go this route, make sure you get the latest version ... they have the metal connectors to power converter.
