The present invention is to realize a simple communication connection. A shooting system S includes: a display device 2 configured to change identifiers periodically so as to present an identifier; a management server 1 configured to share the identifier with the display device 2; and a user terminal 4 configured to acquire the identifier presented on the display device 2 when an identifier acquisition operation by a user is detected, and to transmit, to the management server 1, the acquired identifier and an operation instruction to operate a camera 3 identified by the acquired identifier. The management server 1 includes an information control block 114 which performs control to associate image data acquired with the camera 3 based on the operation instruction transmitted by the user terminal 4 with the identifier presented on the display device 2 when the identifier acquisition operation by the user is detected.
