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

摘要

A monitoring camera device includes a imaging unit (11) for generating image data on a monitoring object, a dynamic image extraction unit (12) for extracting image data from the image data for a predetermined frame cycle, a motion image encoder (13) for generating motion image data obtained by compressing/encoding the extracted image data, a change detection unit (17) for outputting a change detection signal indicating a change of the object, and a transmission processing unit (19) for switching between at least two types of communication protocol according to the change detection signal and performing data transmission processing. The transmission processing unit (19) transmits motion image data to the monitoring terminal device (40) via a network (30) according to a connectionless communication protocol if the change detection signal indicates that there is no change and according to a connection type communication protocol if the change detection signal indicates that there is a change. With this configuration, it is possible to provide a monitoring camera device and a monitoring system capable of appropriately transmitting an image required for judging whether a monitoring object is abnormal.
