Se alguém está curioso, é este aplicativo.
A friend gave me one a few years ago from Canada Computers.
I don't use it any more, to be honest. Not because it didn't work, but because I found a better solution was to repurpose an old Android cell phone and use this dash camera application, instead.
The benefits of this are that since it's connected to the phone's GPS, it shows your car's speed/position at the time of any accident, and it allows you to upload video to a server immediately. That's not really an issue in Canada, but if you go to places where you're worried that cops (or others) will confiscate or trash the camera recording, it's nice to have it uploaded to the cloud automatically. And being just an app, was only about $10. Oh, it also has a database of speed traps, as well, though to be honest, I don't notice that very much, since most of my driving is highway.
The camera my friend got me isn't made any more, but this one looks very similar to my old one.
Looks great! Also, checkout Sygic's version if you need inspiration for more features, may be helful.
