Optical defog function in Savgood Network modules

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.
Weather greatly affects video image quality captured by outdoor camera systems. Depending on weather conditions, the color and contrast of video can be degraded dramatically. “Bad weather” factors such as rain, haze, vapor, dust, and fog affect the quality of captured video. Traffic monitoring and border control must be done under all weather conditions. It’s a major limitation to not be able to recognize if a moving object is a person or an animal, or to not be able to see a license plate number. Outdoor camera systems, especially for surveillance, need to have functionality that can remove unwanted bad weather effects - “fog” - from the video, to improve video quality.
Expectations for a camera’s performance, no matter the application, are that it must work and provide clear usable images, regardless of any environmental or mechanical challenges the camera is exposed to.

Savgood Technology cameras could provide 2 methods: Software Electrical defog and Optical defog technology, to providing defog video enhancement processing capability.

All zoom modules with “-O” in model number can support Optical Defog by default.
