VIOFO A119 V3 Supports 4K Resolution?
Nowadays there are many “4K” dash cams flooding in the market as demand for safety grows. A real 4K dashcam packs 4 pixels into the space that one takes up in Full HD, meaning higher pixel density, more vibrant color and more in-depth image. 4K video footage perfectly restores critical evidence if you’re caught in an accident or trouble with the law as it reads license plates better and even tells if the driver ahead is making a phone call. However most users couldn’t even differentiate between real and fake 4K dash cams.
What is real 4K?
Firstly let’s take a look at how things work in dash cam description. A 4K titled dash cam could have below advertised resolution, 3840*2160P@30fps, 2880*2160p@24fps or 2880*2160p@30fps. But which one of them exactly is a REAL 4K dash cam? In Wikipedia, 4K resolution refers to a horizontal display resolution of approximately 4,000 pixels. In television and consumer media, 3840x2160 (4K UHD) is the dominant 4K standard, which making it plain to see that the above mentioned 2880*2160p@24fps or 2880*2160p@30fps are both fake 4K dash cams. 2880*2160P records at aspect ratio 4:3 resulting details missing from left & right bar while videos @24fps are usually not smooth enough.
What is interpolation?
Normally in order to record real 4K video, a dash cam needs to have an image sensor with at least 8MP, such as VIOFO A129 PRO with SONY IMX317 8MP Sensor, but many fake 4K dash cams have equipped only 5MP, 4MP or 2MP image sensor which originally supports a max resolution of 2560*1600P, 2560*1440P, 1920*1080P. In these cases, they’re interpolated to upscale the image to 2880*2160P from what it actually is, which does absolutely no help improving video quality at all. That’s why VIOFO sticks to real 4K dash cam VIOFO A129 PRO and never tends to interpolate to play tricks on other models.
VIOFO A119V3 supports 4K?
As VIOFO A119 V3 also use the Sony IMX335 sensor, does it support interpolated 2160P resolution? Of course, it can! We have implemented the 2880*2160P 30FPS on V2.5 version. Please download new firmware from below link to have a try.
