70 mai A800 (I think) has been great for me. Simple. Used it for about 3 years. Has a front and rear cam
It's currently USB charged, so no parking recording. Video is crystal clear and great in the dark.
When that dies at some point I really want to look into the T'EYES CC3 360. I wasn't aware you could get after market 360 cams and the main screens they sell (CC3) are pretty powerful compared to 99% of the underpowered Android devices around.
