Abstract

Video monitoring systems usually comprise one or more monitoring cameras directed to related monitored areas such as intersections, parking lots, manufacturing plants, etc., wherein the image data streams recorded by the monitoring camera (S) are often collected at a monitoring center. In the automated evaluation of image data streams, there are known methods that detect moving objects in the monitored area, track them and carry out evaluations based on the detection or tracking. On the other hand, a monitoring module 4 for a video monitoring system 1 is proposed, wherein the monitoring module 4 can be data-coupled and/or is data-coupled to at least one monitoring camera (2), wherein the at least one monitoring camera 2 is directed to a monitored area and the monitored area can be displayed or is displayed as a monitoring scene that includes or can include moving foreground objects and a scene background, and wherein the monitoring module 4 is designed for the analysis of the monitoring scene and for the output of a signal based on the analysis, wherein the output of the signal based on the analysis of the scene background occurs upon deviations in prescribed base states.
