Next, let’s talk about the video quality of these dash cams. The Rove R2-4K Pro dash cam is one of the most affordable “4K dash cams” on the market, equipped with a Novatek NT96670 Processor, a 5MP Sony STARVIS IMX335 Sensor, and an F1.5 Large Aperture 6-Glass that delivers up to a resolution of 2160p. It covers a 150-degree field of view and sports Super Night Vision and WDR, which allows for clearer recording in low-light situations.
However, In our previous reviews for the standard Rove R2 4K, we found out that the dash cam only has a video resolution of 2880 x 2160P @ 30 frames per second, which is lower than 3840 X 2160P @ 30 fps. When running a real 4K dash cam like the VIOFO A139 Pro or the Thinkware U3000. Admittedly, when the upgraded Rove R2-4K Pro was released, we assumed that they would upgrade the resolution into true 4K – and they did. Now, the new Rove R2-4K Pro captures in 3840 X 2160 P and also at 1440P @ 60 FPS. But still, there’s a catch.
4K dash cams are supposed to have an 8MP image sensor, and Rove R2-4K Pro and the Rove R2-4K still use the same image sensor – a 5MP Sony STARVIS IMX 335, which is commonly used in 2K dash cams like the first generation A119 Mini. So, in terms of video resolution, we can also confirm that while the Rove R2-4K does imply that its footage was being recorded at 4K (3840x2160p), but rather it only records in 2K QHD.
The sad truth is that many dash cams, especially the ones you see in Amazon, pretend that they’re 4K. Meanwhile, here goes the VIOFO A119 Mini 2, a true 2K QHD dash cam but captures footage that we can say rivals many 4K rivals.
The VIOFO A119 Mini 2 is VIOFO’s best-in-class 2K QHD dash cam, thanks to its Sony STARVIS 2 IMX 675 sensor that records up to 60 frames per second – frame rate increased! While Sony STARVIS 2 is known for its excellent low-light performance, the VIOFO A119 Mini 2 exceeds expectations with Super Night Vision 2.0, the first in VIOFO. Its highest resolution can be set up to 2592 x 1944P @ 30fps, or 2560 x 1440P @ 60fps.
Comparing the Rove R2 4K and VIOFO A119 Mini 2, we learned that the A119 Mini 2 has the highest sensitivity and lowest noise captures in nighttime driving, which also works best with its High Dynamic Range (HDR) feature. It also offers a wider dynamic range of 78 dB in a single exposure – significantly improving over previous STARVIS sensors of the same size. Pair it with a CPL filter, and a BlackboxMyCar Aqua Shield to keep the view glare- and rain-free, and you’re very close to capturing 4K.
