I’ve thought about using these kinds of camera/common systems but a while ago when I looked into it they seemed to have so-so video footage quality and had so-so battery life. I’d be interested to know what other people think too, currently have a sena and go pro setup.
Looking at their website, I don’t see much about interoperability between brands though, and no specifics on battery life when in use. I’m not sure if you’ll ever get good footage at night though, I haven’t tested that with my gopro so I can’t speak to that.
I bet google doesn’t have to. They can still mine your data and sell it for profit. They’re a data company first after all.
