I flipped the camera to upside down mode and used a 3M mount to stick it to the underside of the bumper where the foglight grilles are. That way the mount is hidden and doesn't really matter if it makes the paint sticky when you remove it. Make sense?
Another idea - you know the grille on the top of the dash?? Buy a spare one and stick a 3M mount there too.
Software, I just use the free iMovie on my Mac.
