VIOFO A229 Pro

This Viofo a229 pro review finds the VIOFO A229 Pro at number two of nine in our best 4K dash cams guide, carrying the Best front and rear dual-channel label. It is a two-camera kit for $279.99: a 4K front camera and a 2K rear camera, both built on flagship Sony STARVIS 2 sensors. The A229 Pro holds a 4.2-star average from 1,507 Amazon ratings. Buy it if you want one lens watching the road ahead and one watching behind, with glare control already fitted. Skip it if you only need forward coverage or if you want cabin footage. Its 140-degree front lens is also narrower than the 165-degree lens on the Vantrue in the same guide.

Sony STARVIS 2 sensors sit behind both lenses, which matters most at night. The front IMX678 captures 4K at 2160p and the rear IMX675 captures 2K at 1440p, each at 30 frames per second. HDR runs on both ends, so highlights and shadows stay balanced and license plates remain readable in headlight glare. In practice, the 2.4-inch LCD handles setup and the 5GHz Wi-Fi link pushes clips to the VIOFO app for previews and sharing. Twelve voice commands lock a file, take a photo or toggle Wi-Fi, and the GPS module pulls from four satellite systems (GPS, BEIDOU, GALILEO and GLONASS) to log speed, time and location. Loop recording overwrites the oldest file once your card fills, while an impact locks the current clip. A CPL filter comes pre-fitted on the front lens.

On top of that, the A229 Pro saves you the cost of a separate polarizing filter and a GPS module, both of which come in the box along with a 6-meter rear cable, a trim removal tool and spare stickers. Even so, it is not the cheapest way into 4K. The hardwire kit for round-the-clock parking power is sold separately, and the memory card is not included either, though the camera accepts cards up to 512 GB. Compared with the Vantrue in this guide, the VIOFO gives you sharper front detail and the fitted CPL, while the Vantrue covers a wider 165 degrees and adds cabin view options. Meanwhile, single-camera 4K models cost less, so buy one of those for a second car and save this kit for the vehicle you drive daily. If you want both directions covered cleanly, this is the one to get.
