I'm new here, and have just been through the long trial of looking for a decent 4K 60P action / dashcam. I compared zillions of actual user footage and even comparison from so called 'pro' reviewers right up to GoPro6.
My background as a broadcaster and subsequent designer and technician has given me a very critical approach and fussy attitude to what I see from recorded video. In the end, bottom line is that I bought the Yi4K+ and am absolutely blown away by how good a product you get for the price. The high data rate limits record time on 4K 60P to about 2 hours, but the quality and detail is just breathtaking. Low light is about as good as you can expect from such a tiny sized sensor with so many light receptors. The GoPro matches it, but certainly not in the absolute detail that this baby dishes out. The feature set is good and the auto orientation options mean you can mount the camera upside down and it will correct the scan to make your video or timelapse come out the right way up. The timelapse options are great for night time stuff, as long as you make the intervals adequate for a suitable exposure time per frame to get a good photo. It will also auto produce a video instead of a series of thousands of stills if you want. I have trawled all the fake claims and I understand the frustration that plagues you guys trying to figure out what the heck a true resolution is. I nearly got caught out recently with the H9 claims ... and then realised it was interpolated to 4K from a smaller res sensor. These things used to be covered under a thing called the 'Trades Description Act' .... where did that go? With the internet and a Global Economy, it seems that we can neither check on the accuracy of product manufacturer claims, nor can we resolve compensation easily without hours of correspondence and threats. One exception, in my experience has been Bang Good ... but then I managed to get an online discussion going with their help chat and immediately found a distinctly reasonable assistant who immediately cancelled an order for 2 x '4K' with Sony IMX chips which blatantly could NOT do genuine 384x2160P at ANY framerate, let alone the 30P it claimed. So that's my experience .. for what it's worth.
