MONITORING CAMERA DEVICE, MONITORING SYSTEM USING THE SAME, AND MONITORING IMAGE TRANSMISSION METHOD

摘要

The invention includes an imaging unit for taking the image of a subject as the object of monitoring, a moving image extracting unit for extracting image data of each frame in every specific frame period from this image data, a motion image encoder for generating motion image data by compressing and coding the extracted image data, a change detecting unit for issuing a change detection signal showing a change in the subject, and a transport processing unit for processing data transport by changing over at least two types of communication protocols depending on the change detection signal. The transport processing unit transports the motion image data to a monitor terminal device through a network according to connection-less type communication protocol when the change detection signal shows no change, or according to connection type communication protocol when showing presence of change.
