Recently, 4K resolution becomes the hot topic, 4K and 8K these phrases can be easily found in both home electronics and video surveillance industry websites. Actually, 4K and 8K firstly appeared in home electronics industry, dated back to 2012, International Telecommunication Union passed the 8K SHV TV standard which delivers 7680×4320 image resolution originally derived from NHK TV station.
Although there are many articles talk about this topic, we believe some of you may not clearly know the definition of FHD, 4K, 8K. Therefore, we write this article to provide you detailed knowledge about these TV resolution standard.
Resolution is the "Overall picture sharpness" and it's measured by counting horizontal lines (horizontal resolution) and vertical lines (horizontal resolution) of an image. The white lines are also counted as a line in the picture. In other words, resolution quantifies how closely the lines are to each other and yet still be visibly counted.
With increased demand for higher resolution, especially in high-end displaying area, requires much higher resolution display equipment. From the first 480P CRT TV, to 720p, 1080p, 2K, 4K, 8K etc resolution display equipment, image resolution has been gradually increased. 480p, 720p has been outdated, while 2K resolution is generally used in professional cinema players.
FHD: 1920x1080
Talking about FHD, foremost we need to know the current HD format available in the market, this info helps us to know FHD resolution. In the market, HD resolution includes: 720p, 1080i, 1080p, 720p means vertical resolution is 720 TV lines adopting progressive scan; 1080i means vertial resolution is 1080 TV lines adopting inter-laced scan; 1080p means 1080 TV lines vertical resolution adopting progressive scan, 1080p is the most clear resolution format among them. FHD is the abbreviation of full high definition, some people call it 1080p, the actual image resolution is 1920×1080 (including 1080i and 1080p), equal 2 megapixels.
FHD, is the highest resolution standard in current global HDTV standard. Simply speaking, a full high definition network camera must support 1920×1080 physical resolution, besides, screen aspect ratio must be 16:9, as long as meeting these specification, they are HDTV network cameras. FHD is the current popular video resolution, most of network cameras support 1920×1080 image resolution.
4K: 4096×2160
According to the analysis from video surveillance manufacturers, 4K will become the video resolution standard within 2 years. 4K image resolution can offer 8 megapixel, to achieve cinema grade quality image, it's four times larger than 1080p resolution. Apparently, 4K also brings some setbacks such as higher network bandwidth, video storage capacity, as well as required high performance video encoder and decoder.
4K's name originally comes from approximate 4000 pixel horizontal resolution, in Cinema industry, the regular 4K resolution including full aperture 4K (4096 x 3112), Academy 4K(3656 × 2664) etc multiply standard. 4K ultra high definition video film means its image resolution is 4096×2160. To main network video surveillance manufacturers, they tend to produce the products with Quad Full HD(3840×2160) image resolution, since this 4K resolution maintains 16:9 video aspect ratio.
8K: 7680×4320
8K image resolution can reach up to 7680×4320, which is sixteen times larger than full high definition, or four times larger than 4K UHD resolution. 8K equals 33 megapixel can provide super vivid image and deliver perfect visual sense.
