Abstract
The invention relates to a smoke detection device (1) for detecting smoke (7) from a fire (6) in a monitoring area (3), comprising a camera interface (8) for receiving an image sequence having chronologically successive individual images from a monitoring camera (2), wherein the individual images (4) show the monitoring area (3), and comprising an evaluating device (9) for detecting at least one moving object in the monitoring area (3), wherein the evaluating device (9) is designed to detect a motion of the at least one moving object from at least two individual images (4) of the image sequence (5), characterized by a filter device (10) for distinguishing the moving object as smoke (7) or as a non-smoke object on the basis of the motion of the moving object.
