Viofo sent me this early unit to test and review, but they had zero input in the contents of this review. I did not receive any compensation for the review other than getting the test unit.

The Viofo A139 is a 4K dash cam with either a 1-channel, 2-channel, or 3-channel configuration where the interior and rear cameras are 1080p. I was very impressed with the quality of this dash cam, but I did have some issues with parking mode not triggering correctly when there was motion.
