4K CCTV camera Technical advantages

First of all, the most obvious 4K technology performance is that its display resolution is improved, making the picture more detailed. There are two important key factors affecting the fineness of the picture, one is the pixels of the picture, and the other is the vertical resolution of the picture. The higher the pixels of the picture, the finer the pixels on the same size picture, and the smaller the lattice. And because the human eye is quite sensitive to the vertical resolution of the image, the higher the vertical resolution, the more detail and layers the human eye can recognize. What 4K technology can achieve in the field of monitoring is to increase the vertical resolution of the picture while increasing the pixels, making the details and levels of the picture more accurate.

Secondly, the enhancement of color levels and details makes the picture closer to real life. The change from standard definition to high-definition display systems is actually mainly an upgrade in resolution, and there has been no significant improvement in color. However, in the era of 4K ultra high definition, in addition to the leap in resolution, the changes in color are particularly noticeable. This part is reflected in the latest BT.2020 ultra-high-definition broadcasting standard promulgated by ITU-R.

Finally, 4K video systems process 10-bit or even 12-bit encoded video signals. At present, HD or Full HD systems usually use 8-bit video systems, while 4K Ultra HD uses 10-bit or even 12-bit video systems. Therefore, whether it is the gray-scale secondary transition or the color depth, the performance is greatly improved compared to the high-definition system.
