70mai 360 Omni 4K Dash Cam review: as good as it gets

The 70mai 360 Omni 4K Dash Cam is a new and improved version of an earlier model, which was a neat idea but with a lower specification. The latest incarnation addresses that issue, adding in 4K shooting capability via a beefier Sony Starvis 2 IMX678 sensor that captures 3840 x 2160 footage at 60 frames per second. There’s also the addition of a microSD card slot plus boosted video capture tools, including AI Motion Detection 2 and the Lumi Vision tool for shooting better video after dark.
