Hikvision Digital Defog Technology

Surveillance cameras installed outside are expected to stand the test of 24/7 operation through strong light, rain, snow, and fog. Aerosol particles in the fog are especially problematic, and remain one of the main causes of degrading image quality. At present, one common approach for defogging an image is a specific optical component that detects more IR information in fog. One of the liabilities of this physical means is its high cost.

Advancements in digital technology have brought about a new defog image process. This whitepaper offers an in-depth look of Hikvision’s digital defog technology, which can adjust the distribution of the information captured by the image sensor, enhancing the color and details of the surveillance target.
