Our pick

U3000 Pro combines radar-led parking with a pre-event buffer and front and rear recording. ARC900 is better when you want to review the clip on a touchscreen at the car. BlackVue ELITE 9 adds a 1TB ceiling and an optional cloud path.
The useful clip starts before the impact, which makes buffering and power setup more important than resolution alone.
