<p>A security camera system (100) detects misting within the transparent portion (112) of the security camera system (100) by analyzing the actual images (210) that are captured by the security camera system (100) in order to determine whether or not there is misting on the transparent portion (112). Specifically, video analytics are applied to detect areas of the scene that appear to be out of focus as a result of misting of the transparent portion (112) of the security camera system (100), also known as the bubble. The system uses, in a preferred embodiment, an edge- detection algorithm to look for areas (212, 214) of the scene that appear to have gone out of focus. When these are detected, the condensation mitigation system (114, 116, 118, 120) is activated in order to remove any misting.</p> |
