Our pick

A810 Lite covers both ends of the car with native 4K ahead and 1080p behind. It also gives you a screen, GPS, quick phone transfers and a 512GB card ceiling. Choose the ROVE R2-4K Dual Pro when rear detail and an included 128GB card matter more. Thinkware ARC900 is the stronger parking-first alternative.
A strong everyday camera should cover both directions, handle difficult light and keep clip retrieval manageable.
