Defog Technology

Sunday, July 10, 2016 6:34:36 PM America/New_York

These environmental conditions have a great influence on the image quality of the surveillance camera, especially the fog. The aerosol particle containing moisture and fumes in the fog is the main cause for the degrading of the image quality.
