Abstract: A method and apparatus for analyzing a dirty camera lens to determine if the dirty camera lens causes a failure to detect various events is provided herein. During operation, a filter is created that, when applied to previously-recorded video, mimics a dirty camera lens currently existing on a camera. The filter can then be applied to video taken previously with the camera as a result of an event being detected. The video analytics to detect the event are run again on the filtered video to see if the event is again detected. If the event was detected in both the filtered and unfiltered video, it is assumed that the particular event can still be detected even with the dirty lens. If the results differ, an alert can be sent to an operator indicating that the camera may no longer be capable of detecting the particular event.
