I never tried to install rear cam too.
i read the same article like you but my friend using Viofo A119, he say its overrated
But im still going to get A129 becoz this price cant get better dual dashcam

Viofo A119 have 3 version. Viofo A119, Viofo A119S and Viofo A119 Pro. The difference is the lens and sensor, so different quality.

What's the benefit of using a dual cam system compared to 2 standalone for front and back?
Timing, if dual then video have same timing. when edit you have a better video. In the events of accidents, every seconds
count.
In case using dual, if 1 detected a hard hits, both will record a secured video.
If 2 single units, maybe front will detected that, so rear won't record a secured video.
also when want to record secured video manually, how to press a button on rear one?
