Abstract
A system and method for securing an edge zone in a space, while not restricting normal activities in the space, is provided. The system and method comprises an infrared detection device and a data processing means. The infrared detection device monitors a space using two or more fields of view. Some of the fields of view cover an edge zone of the space, while the rest of the fields of view cover an adjacent zone to the edge zone. The infrared detection device produces a signal when one or more infrared sources, such as human beings, enter one of its fields of view, in which the signal is unique for identifying the field of view being entered. The data processing means processes the signals from the infrared detection device for securing the edge zone with either intrusion detection or escape detection. The data processing means produces an alarm signal when an intrusion or escape is detected, but does not produce such a signal for normal activities in the monitored space, including the edge zone.
