4K and Ultra HD are four times the resolution of Full HD. A standard Full HD screen will have a resolution of 1,920 x 1,080 (a total of 2,073,600 pixels). Ultra HD and 4K screens have a resolution of 3,840 x 2,160 (a total of 8,294,400 pixels). The more pixels there are, the more detail the picture contains.

4K has not only been adopted by the television industry as a standard but is also becoming the new norm for video-based security systems, promising better image quality and richer detail.
