The Viofo A139 is a solid 3-channel choice with excellent overall video quality, decent reliability and a whole host of features. It represents one of Viofo’s forays into the midrange dashcam market, and upholds the brands positive reputation as a quality manufacturer.
The Zenfox U1 is a competent camera (without notable overheating issues), reasonable video quality for the price, and several features found on higher end cams. The slightly soft focus prevents the cam from being a home-run, although if you’re watching the video on a small screen, chances are you won’t be able to notice.
The Viofo A129 is my current camera of choice, replacing my previous daily driver set up of the A119 + A119S. The A129 is a worthy successor to these cams, featuring clear dual 1080p with great night video. This is one of the first dual dashcams that I can recommend with ease, despite some little things that could be improved. If you want a single forward facing cam, get the Viofo A119 instead. If you want a front and rear setup without the hassle of wiring two separate cams, the A129 is a decent budget choice. And don’t forget a good memory card to go with this camera.
The Viofo A119S is a low profile dash camera based on the A119 form factor however there are two main differences: the camera uses an updated lens with a narrorwer field of view, and it contains a Sony imaging sensor that is capable of a max resolution of 1080p at 60 FPS.
Overall, in my opinion, it is worth the extra money for the A119 until Viofo releases a firmware update to improve the exposure rendering of the A118C2 and even then the performance can only be improved so much. The video on the A119 is sharper and it has 1080p60, as well as 1440p.
Overall, my recommendation is to spend a bit extra and get the A119 over this camera. The video quality is higher in daylight, because the A119 does a better job with colour, shadows and highlights, and the night video is close enough to call it a draw. The A118C2 is an OK camera, but there is better value available for just a little bit more money.
For most users, who want a dash cam in their daily driver, the adhesive mount is the way to go because it is very low profile, stands up to heat and is semi-permanent. The downside is that it is difficult to remove, if needed. The suction cup mount is good for a first dash cam or for one that will be used in multiple vehicles. Just keep in mind that if you have these little black dots it is hard to hide the camera behind the rear-view mirror. Rear view mirror cameras, I wouldn’t currently recommend getting but that may change in the future.
In most cases dual lens dash cams are a bit too expensive to be worthwhile because they do not offer the same video quality as single channel dash cams.
At $100, this camera outperforms every other camera I’ve used in its price range, and even some cameras that are far more expensive. Viofo has a good track record of making quality devices that last a long time. That means this camera has a lot of value. It would be silly to spend more money for only a marginal increase in performance.
This video puts two 2k cameras side by side. Viofo takes the edge, with slightly sharper video and a super-capacitor. The Vantrue has slightly better color/exposure and less distortion.
