INTRUSION DETECTION WITH DIRECTIONAL SENSING

摘要

A method and system of intrusion detection, which includes displaying sensing device output data as one or more images of a field of view of a sensing device (14.1, 14.2, 14.3). Through interaction with a graphical user interface: a user input to define and display an image detection area in relation to the one or more images of the field of view is received, wherein the image detection area is correlated to a detection area to be monitored by the sensing device (14.1, 4.2, 14.3) for intrusion detection. One or more user inputs that define a detection vector in the image detection area are received, the detection vector specifying a predetermined minimum displacement and direction of displacement in the field of view to be monitored. A graphical representation of the detection vector may be displayed on the image detection area. The method further includes detecting a target object and tracking the target object at least partially through the detection area and determining whether the progressive displacement of the target object has a component which exceeds the minimum displacement in the direction of the detection vector.
