Noises in the CCTV image can cause serious problems. Darkening or bright spots in the frame make it difficult to see the details of what is happening. Because of this, the level of protection of the territory/object suffers greatly. How to suppress video noise? 3D DNR technology will help to solve the problem. We will talk about it in this article.
3D DNR is digital noise reduction in a video surveillance system. Usually, noise appears on cheap cameras.
That is why we do not recommend buying hardware on AliExpress. Untested devices fail faster than the warranty expires and generally fall short of expectations regarding value for money.
And if moisture appears on the lens of your camera, then read our special article: “7 Ways to Get Rid of Condensation on a CCTV Camera”.
Innovative 3D DNR technology suppresses video noise and reduces spatial noise. In the process, the rows of pixels are compared, and the whole frame is processed. As a result, the picture quality is improved.
The image is improved by removing two types of noises:
To be sure of the quality of video surveillance, you need a combination of the following factors:
If you are planning the development of the system or you need video analytics, then choose cloud technologies such as the Faceter service.
With 3D DNR, you get not only clear video monitoring but also the following benefits:
3D DNR technology is an excellent assistant for video monitoring at night.
It is necessary to eliminate the problem of the quality of shooting in video surveillance as soon as you notice it. Otherwise, at the most crucial moment, the noise will fill up a vital frame.
And if the 3D DNR technology did not help, then you may have encountered the usual interference. Read about how to deal with them in the article “5 Proven Ways to Avoid Interference in the Video Control System“.
