1. A method for visualizing ( 200 ) zones of higher activity ( 220 , 230 , 240 , 250 ) in a surveillance scene monitored by at least one surveillance apparatus ( 111 , 111 ′, 111 ″; 210 ), the method comprising: a) at least one of identifying and tracing ( 102 , 102 ′, 102 ″) moving objects ( 112 , 112 ′, 112 ″) by the at least one surveillance apparatus ( 111 , 111 ′, 111 ″; 210 ), b) establishing ( 103 , 103 ′, 103 ″) a spatial localization ( 113 , 113 ′, 113 ″) of the moving objects ( 112 , 112 ′, 112 ″) in the surveillance scene, and c) determining and visualizing ( 200 ) zones of higher activity ( 220 , 230 , 240 , 250 ) of the moving objects ( 112 , 112 ′, 112 ″) in the surveillance scene.
