  In step S304, the CPU 201 of the video recording device 300 receives the video transmitted from the imaging device 200 in step S303. Then, the received video is stored in the recording unit in association with identification information (ID or IP address) of the imaging device that is the imaging source.

  Note that the processing of steps S301 to S304 is repeatedly executed at regular intervals. In addition, when there are a plurality of imaging devices 200, video is acquired from each imaging device 200.

  In step S <b> 305, the CPU 201 of the client terminal 100 transmits a camera ID to the video recording apparatus 300. The camera ID transmitted at this time is an ID that is not associated with the camera IP address.

  In step S306, the CPU 201 of the video recording apparatus 300 receives the camera ID and the video acquisition request transmitted from the client terminal 100.

  In step S307, the CPU 201 of the video recording device 300 acquires a video corresponding to the camera ID acquired in step S306 among the videos recorded in the recording unit.

At this time, the identification information (ID) of the imaging device (camera) that captured the still image generation source video is also transmitted.

  In the present embodiment, a mode in which a still image is generated and transmitted will be described, but it may be a moving image instead of a still image. In that case, the client terminal 100 executes processing for generating a still image from a moving image.

  In step S309, the CPU 201 of the client terminal 100 receives the still image transmitted from the video recording apparatus 300 in step S308.

  In step S <b> 310, the CPU 201 of the client terminal 100 transmits a real-time video acquisition request to the imaging apparatus 200.

  In step S314, the CPU 201 of the client terminal 100 acquires a still image from the video received in step S313.

  In this embodiment, the client terminal 100 executes a process of generating a still image from the video. However, the imaging device 200 generates a still image, and the client terminal 100 acquires the still image generated by the imaging device 200. Also good.

  In step S315, the CPU 201 of the client terminal 100 compares the still image received in step S309 with the still image received in step S314, and determines whether the similarity between the two satisfies the reference value.

  That is, it is determined whether the images are still images acquired from the same imaging device or still images acquired from different imaging devices.

  If the similarity satisfies the reference value (that is, if the images are still images acquired from the same imaging device) (S315: YES), the process proceeds to step S316.

  When the similarity does not satisfy the reference value (that is, when the still image is acquired from a different imaging device) (S315: NO), the process proceeds to step S305.

  In calculating the similarity, feature amounts such as image colors and edges are extracted, and the feature amounts are compared to calculate the similarity.

  In step S316, the CPU 201 of the client terminal 100 records information in which the camera ID is associated with the camera IP address.

  Through the above processing, the client terminal 100 can manage the camera ID and the camera IP address in association with each other.

  The client terminal uses the camera ID to acquire the video shot by the imaging device identified by the camera ID from the video recording device.

  In addition, the client terminal acquires the video imaged from the imaging device by directly setting the IP address.

  Then, the image acquired via the video recording device using the camera ID and the image directly acquired from the imaging device using the IP address are compared to determine whether the similarity satisfies the reference value. When it is satisfied, it is determined that the image is taken by the same imaging device, and the camera ID and the IP address are managed in association with each other.
