Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To facilitate the enlargement of a monitoring area and the change of a function and to stably trace an object by installing an object monitoring device and an inter-monitoring area corresponding device in a small monitoring device.
SOLUTION: In a small monitoring device 111 used for a wide area monitoring device, an object monitoring device 202 monitors the inner part of a covering small monitoring area with the sensor of a camera, extracts and traces an object and obtains the attribute of the object. An inter-small monitoring area corresponding device 201 obtains the attribute of the object invading into the covering small monitoring area from the adjacent small monitoring area through a network 130. The inter-small monitoring area corresponding device 201 makes the object grasped in the adjacent small monitoring area correspond to the object grasped in the covering small monitoring area from the attribute of the object, which is obtained through the network 130, and the attribute of the object, which is inputted from an object monitoring device 202, when the invaded object exists in the covering small monitoring area.
