SURVEILLANCE METHOD, SYSTEM AND MODULE

摘要

A method of monitoring monitored locations by means of a monitoring system. The monitoring system comprises a plurality of monitoring modules (1), each of which has a light-sensitive sensor for monitoring the monitored locations. The monitoring system further comprises a remote monitoring station (3) with an operator. The method comprises the steps of recording by each of the monitoring modules (1) an image of the monitored location associated with the monitoring module (1), extracting in each of the monitoring modules an area in the recorded image that differs from a reference image, and extracting in each of the monitoring modules an object from the area. The method further comprises classifying in each of the monitoring modules (1) the object based on characteristics, such as a characteristic of the type: size, shape and/or movement history, associated with the object, if the object is a human alarm object, and if the object is classified as a human alarm object, transmitting data representing the area in a stylized way to the monitoring station (3), and recreating said transmitted data in the monitoring station (3) and displaying the same to the operator for verification of the human alarm object.
