Abstract
A smoke detection apparatus 1 is proposed, the smoke detection apparatus 1 being able to be connected to at least one monitoring camera 2 which is designed to record images of a monitoring area, the monitoring area comprising at least one stationary contrast pattern object 3, having an evaluation device 5, the evaluation device 5 being designed to detect the at least one contrast pattern object 3 in the images transmitted by the monitoring camera 2, the evaluation device 5 evaluating a change in the contrast pattern object 3 in the images as at least one smoke detection feature in order to detect smoke, the evaluation device 5 being designed to evaluate a contrast deviation between an upper contrast pattern section 4a and a lower contrast pattern section 4b of the at least one contrast pattern object 3 in at least one of the images as the at least one smoke detection feature.
