Many dash and action cams now have a very wide angle lens which gives a lot of distortion at the edges. I have been trying to find a replacement for my dash cam with no more that 120° wide angle lens and GPS. I have tried a couple of alternatives one I sent back becuse it was faulty but I did not get a replacement because I was not entirely happy with the software. I also tried a Sony Action Cam but it vibrated too much to give a decent video and I returned it too.
I've been using a Mobius camera in my daily driver for the last two years. I've installed it behind the rear view mirror in a fit a forgot manor. It's been excellent to date.
I've not got around to installing one in the Morgan as I can't think of a suitable discrete fit and forget solution....
This is one, it's about the size of a small matchbox:
