Now the 4K camera products launched on the camera market have become mainstream, but many people don’t know the difference between 4K and HD cameras? When I bought it, I wondered which one to buy? Today, the editor will introduce to you in detail what is the meaning of camera 4K and the difference between camera 4K and HD.

一、4k technology introduction
Compared with high-definition cameras, 4k cameras are undoubtedly the new favorite, we will focus on understanding 4k technology. The obvious performance of 4K technology is that the improvement of its display resolution makes the picture more refined. There are two important key factors that affect 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 picture of the same size, and 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 details and levels the human eye can recognize. What 4K technology can achieve in the surveillance field is to increase the pixels while also enhancing the vertical resolution of the picture, making the details and levels of the picture more.


二、The difference between 4k and HD cameras
1, the concept of 4k camera
4K refers to a resolution of 4096×2160 and an aspect ratio of 16:9. Under this standard, CMOS progressive scanning can reach 2160P. Compared with 2 million pixels, the 4K high-definition network camera has higher vertical resolution, higher level of picture detail, clearer display, cleaner and more delicate, and more immersive feeling, which can effectively solve the need The monitoring needs of high-definition picture quality and complex lighting.

2, the concept of high-definition cameras
High-definition means high-resolution, and high-definition cameras are capable of high-quality and high-definition images. The captured images can reach 720-line progressive scanning with a resolution of 1280*720, or reach 1080-line interlaced scanning with a resolution of 1920* 1080 cameras.
