FitcamX dashcam. Anybody installed one?

[verdee]

I want to get a dashcam for my car. I really like the integration the fitcamx offers. I emailed them and they recommended Audi Model A (HD2-7708) for the car, which looks similar to the Porsche model A on their site. I want to make sure I’m ordering the correct one.

Interesting they recommend Audi Model A, and not Porsche Model A. Any reason they explained?
Good thing about this dashcam is it does not need a lot of wiring or a separate battery.
But would a battery be needed for the rear dashcam?
