Maybe is looking better only during day. People are paying much money on dashcams because they want good image also during night.Guys is it me or does this new Aptina AR0521 look better in every situation to me. Any good dash cams using it. I am tired of these 1080p Sony sensors.

Because you are tired about Sony 1080p sensors maybe is time to prepare for the Sony 2K sensors like IMX335 Starvis.
Right now a good dashcam during night can be only with a Starvis sensor from Sony. Maybe in next 5-10 years Aptina will create the same which is creating Sony now.
If you take a modern plastic framed window with a single sheet of glass and replace it with four separate pieces of glass joined by strips of wood, the window is still the same area, but you get less light because the wood blocks a lot of light. That is the equivalent of going from 1080 to 4K, to reach your 48 megapixel sensor you need not 4 pieces of glass, but 16 pieces, and the wood will block so much light you will have to use expensive lead to join the pieces, but you will still loose a lot of light!I read about a phone with a 1/2 inch 48 megapixel main camera ( IMX586 ) , when low light you can do a 4 in 1 pixel binning to get better low light performance and so give you "a pixel" of 1.6 X 1.6 micron instead of the actual 0.8 X 0.8 micron each pixel are.
But to me it feel like with these high pixel count phones, well shooting pictures in the binned mode and so a lesser resolution are often better than if you shoot pictures in the sensors native resolution.
Which are strange to me as i am talking about daylight pictures here and not just night time pictures.
Also taking those low light pictures well it seem like to be several pictures stacked on top of each other, and so take a while to snap a picture like that in low light and so probably wont do well with movement in the frame.
aside from pixel size Starvis are BSI sensors which works better than an equivalent pixel size FSI sensor, 4K sensors will still need to be a bigger format to do as well, smaller pixel size would still put them at a disadvantage compared to the larger pixel size of 2MP sensors, there's more to it than just the sensor used, there are cameras around that use good sensors but still don't do that well in low light
