How to choose 4k ultra HD surveillance camera

First of all, you need to understand what is 4K ultra HD camera, 4K refers to the resolution of 3840*2160, aspect ratio of 16:9, under this standard CMOS progressive scan can reach 2160P. Compared with 2 million pixels, the high-definition network camera using 4K has a higher vertical resolution, a more accurate level of detail, a clearer, cleaner and more detailed display, and a more immersive feeling, which can effectively solve the monitoring needs of high-definition picture quality and complex lighting places.

The most obvious performance of 4K technology is that its display resolution has been improved, making the picture more detailed. There are two important key factors affecting the fineness of the picture, one is the pixel 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, the smaller the lattice. Because the human eye is very sensitive to the vertical resolution of the image, the higher the vertical resolution, the more detail and level the human eye can discern. Secondly, the enhancement of color levels and details makes the picture closer to real life.

For video surveillance, image clarity is undoubtedly the most critical feature. The clearer the image, the more obvious the details, the better the viewing experience, and the higher the accuracy of applications such as intelligence. So image clarity is the eternal pursuit of video surveillance. How to choose a better 4K surveillance camera, under normal circumstances, you need to understand all the functions that the surveillance camera should have, according to the application environment to choose whether it needs day and night conversion, wide dynamic, noise reduction, fog penetration, HLC (high highlight correction function, take the license plate at night, will not be exposed) and other functions, 4K monitoring can be applied to ultra-wide lane monitoring, safe city panoramic monitoring, public security GIS map command and so on.
