What is 4K? We can tell you for sure that it isn’t a standard definition, not high definition, and not in the slightest a HD resolution! 4K is 4 times HD! It has a resolution of at least 3,840 x 2,160 pixels, which is four times of full HD’s 1,920 x 1,080 pixels. More pixels means more detail and better clarity, especially when viewing on a large monitor. This is big for drones, as the higher resolution means that images and videos will look clean and it will be easier to find certain details during inspections.
