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

Smoke detection device, method for detecting smoke from a fire, and computer program

A device and method for detection of an event in a monitoring area. The detection device includes a camera interface for transferring at least one image of the monitoring area, an image analysis unit configured to determine event specifications for at least any one position in the monitoring area, an alarm unit configured to define an alarm based on a comparison of alarm specifications with the event specifications, a storage unit configured to store the event specifications for the at least any one position, a calculation unit configured to determine at least one false event area based on the event specifications and the alarm specifications, and a masking unit configured to automatically modify the alarm specifications within the at least one false event area, exclude the false event area from the determination of event specifications by the image analysis unit, or both.
