Abstract

In a networked camera system and a monitoring method thereof, each networked camera has camera information for discriminating the respective apparatus, and an index server, registering the camera information of the respective networked cameras therein, makes search for connection information to the networked camera corresponding thereto, responding to a monitoring target required from the networked monitor, upon the basis of the camera information registered, thereby transmitting it to the networked monitor. The networked monitor connects to a predetermined networked camera upon the basis of the connection information, so as to request a picked-up picture therefrom, thereby displaying the picture transmitted from the networked camera. The networked camera and the networked monitor make transmission of the picked-up picture through the mutual connection therebetween, but without passing through the index server. Therefore, the networked camera system and a monitoring method thereof can be provided, in which everybody can set up the camera easily, so as to display a picture desired with easy operation, and further is high in immediacy and stability thereof.

4. The networked camera system, as described in the claim 1, wherein said register registers network address and position information of said networked camera relating therewith, when registering said networked camera information therein.

5. The networked camera system, as described in the claim 1, wherein said networked monitor comprises a controller for controlling destination of connection by said connection requesting unit.

6. The networked camera system, as described in the claim 5, wherein said networked camera has a detector for detecting an object as being a monitoring target, and said controller of said networked monitor controls, so as to receive the monitor picture from said networked camera picking-up the object, which is detected by said detector.

7. The networked camera system, as described in the claim 6, wherein said object comprises a unit to be detected by said detector.

8. The networked camera system, as described in the claim 7, wherein said detector of said networked camera is a sensor for generating radio waves, and said unit to be detected of said object comprises a unit for generating radio waves for response when detecting said radio wave.

9. The networked camera system, as described in the claim 8, wherein said detector receives latitude and longitude information from a system enabling measurement of the latitude and the longitude, and transmits said latitude and longitude information to said index server or said networked camera, thereby using it as a function of a sensor through detecting that it is within a region of the latitude and the longitude, which said network camera sets.

10. The networked camera system, as described in the claim 5, wherein said register registers an ID of said object and an ID of the networked camera, which captures said object on the sensor thereof.

11. The networked camera system, as described in the claim 1, wherein said networked monitor transmits said connection information to other networked monitor, and the other networked monitor makes a connection request to the networked camera having said connection information, to receive the monitor picture from said networked camera, thereby conducting exchanging control between said plural number of networked monitors.
