Title:
MONITORING DEVICE
Document Type and Number:
Japanese Patent JP2006074317
Kind Code:
A
Abstract:

To provide a monitoring device by which an entire invading object can be photographed.

A plurality of infrared ray sensors 4a, 4b, 4c, 4d are installed in the vicinity of the lens 11 of a camera 1 in such a way that the center section 13 of the camera 1 at its photographing range 12 roughly matches the center section 42 of the entire detection range 41. Signal levels complying with a change in infrared rays caused by the invading object obtained by the plurality of infrared ray sensors determine a deviated direction between the center section 13 of the photographing range 12 and the location of the invading object. The photographing range 12 is moved in the direction of the invading object to track, photograph, and monitor the invading object.
