I noticed one such fade to nothing shut down too, but if it resulted in a corrupted file i cant recall / tell
I have had corrupted files 2 times now, once on first files right after boot, and once on the last files.
But it is not a regular thing at all, by far the camera perform normal,,,, but of course not used it for long time yet
I did perform a short test using a PSU from a SG camera, that worked just fine in regard to recording the 3 video streams.
But i am of course carrying on with the provided power supply, the SG one was just my only option to get the camera down on the dashboard as the power wire go to the R A pillar, and the rear camera go to the L A pillar and then put back.
