4K is the next big thing in video. While 1080p has become the 'standard' for HD, the next step is 4K, quadrupling resolution / pixel count from ~2MP to ~8MP. It is already showing up in TV sets as well as consumer cameras. Indeed, the first 4K surveillance camera was announced this spring, with many more announcements certain to follow this fall.
Can 4K really make a difference for surveillance? Or is Axis right that the 'megapixel race is over'?
We bought a GoPro Hero3 Black camera that delivers 4k resolution (indeed up to 12MP). What is especially interesting is that they use the same chip manufacturer (Ambarella) used by cameras from many well known manufacturers (like Avigilon, Bosch, Pelco, Hikvision, Honeywell, etc.).
We took the Hero 3 Black and put it to the test at FoV widths from 20' to 160' feet to understand 4K performance.
We tested at 12MP, 4K, 1080p and 720p to determine what actually quality difference each resolution / pixel count delivered.
