Abstract: The invention relates to a device that receives images from one or more cameras, process images and automatically detects unknown humans in the field of view of the camera, for example to prevent burglary. In order to do so, the device comprises a processing logic configured to detect faces, recognize faces and verify if a face corresponds to a face in a collection of faces of known humans. If a face is detected, but does not correspond to a known face, an alarm event is triggered. The processing logic is further configured to classify objects in the image in classes of object comprising at least a human class. If a human is recognized, but no face has been detected for this human, an alarm event is also triggered. Thus, an alarm can be triggered in any case wherein a human is detected, which is not a known, trusty human.
