The design of the Viofo A139 is all in black. There is nothing special about it, to be honest, very basic. Yet the material quality is very good. You can’t say that it’s cheap from the feeling of it.

My first concern is not finding enough cables to connect the rear cameras with. Yet there are plenty of cables in the package. The rear camera is very small comparing it to the main unit, yet of very good quality.

The Viofo A139 has a 2K front camera, with both back cameras being 1080p. The framework boots up extremely quickly; I’d say inside 5-seconds of beginning the vehicle, the framework says it is recording. 

The recording is acceptable, and obviously, climate conditions and lighting will play a factor in how the image looks. You can add more differentiation and other minor picture changes in settings. 

I don’t see a significant distinction in quality between the 2K front camera and the 1080p back cameras. The distinctions are inconspicuous and slight. I would have jumped at the chance to see the front camera using a 4K sensor all things being equal. 

That doesn’t mean these cameras are awful, they are entirely acceptable however could be better. 

The units appear to hold up fine in searing conditions also. The 3M tape appears to hold solid even on days where it was more than 100 degrees. 

In general, the Viofo A139 performed very well without any issues whatsoever. I do wish the front camera had a 4K sensor rather than 2K.
