Blackvue DR900S-1CH dashcam for the rear window

I received the dashcam. Before I mounted it in front, I had a look if it would fit in the rear.
Sadly the heating wires in my rear window are 23 mm apart. So there is always a tiny line visible at the edges of the pictures.
If only the mount were a a few millimeters lower, I would have clean pictures.

I have to drive another 50 hours to complete the map, and I find it a waste of money not to do it on both sides when there is not much traffic.
