If the image analysis unit 203 determines in step S111 in FIG. 11 that a moving body image has been detected, the image analysis unit 203 outputs a moving body image detection signal to the recorded image data generation unit 201 and the alarm signal generation unit 202. In step S112 of FIG. 11, the alarm signal generation unit 202 generates a moving image detection alarm signal. Further, the recorded image data generation unit 201 reads out the image data stored in the first memory 24, and as shown in FIG. 12, the preset time before the time t2 when the moving body image detection signal is input, Image data for a total time including the post-setting time after time t2 is extracted to generate recorded image data. The generated recorded image data is stored in the second memory 25. Since the time required to analyze the image data is very short, the image data analysis start time and the moving image detection time are substantially the same. Therefore, as shown in FIG. 12, the recorded image data before and after the time t2 when the moving object detection signal stored in the second memory 25 is input is substantially the same as the recorded image data before and after the time t1 when the unlocking signal is input. It becomes continuous image data.

Then, as shown in steps S113 to S114 of FIG. 11, the camera device 20 outputs a moving object image detection alarm signal when polling is input from the communication device 26. Further, as shown in steps S115 to S116 of FIG. 11, when the recording image data transmission request is input from the communication device 26, the recording image data is output to the communication device 26.

After outputting the recorded image data to the server 40 in step S116 of FIG. 11, the camera device 20 proceeds to step S117 of FIG. 11 and waits until a predetermined time elapses after detecting the moving body image. Then, after a predetermined time has elapsed, the process returns to step S110 of FIG. 11, the image data is analyzed again, and when a moving body image is detected, a moving body image detection alarm signal and recorded image data are generated and transmitted to the communication device 26. Output. The communication device 26 transmits the moving body image detection alarm signal and the recorded image data to the server 40.

In this way, the camera device 20 repeats the operation of analyzing the image data at a predetermined time interval and, when a moving body image is detected, generating a moving body image detection alarm signal and recorded image data and outputting the same to the communication device 26. .. The communication device 26 also transmits a moving image detection alarm signal and recorded image data to the server 40 each time.

The moving image detection alarm signal and the recorded image data output to the communication device 26 are transmitted to the server 40 by the same operation as that of the entry/exit management system 100 described above. The user can view the recorded images before and after the time t1 when the unlock signal is input and the recorded images before and after the time t2 when the moving object detection signal is input, on the mobile terminal 50.

In this way, the entry/exit management system 101 outputs the moving object detection alarm signal and the recorded image data to the communication device 26 and the server 40 at a predetermined time interval while the delivery company 60 stays in the shipment receiving room 111. Therefore, it is possible to monitor the behavior of the delivery company 60 from entering the shipment receiving room 111 to leaving the shipment receiving room 111, and it is possible to improve security.

On the other hand, when the delivery company 60 exits the shipment receiving room 111 before the elapse of a predetermined time, there is no image whose position changes in the frame of the moving image acquired by the camera 21, so that the image analysis unit 203 is a moving object. No image is detected.

When the image analysis unit 203 does not detect a moving image, the camera device 20 determines NO in step S111 of FIG. 11, proceeds to step S118 of FIG. 11, and ends confirmation time longer than the predetermined time described above. To determine if has passed. Then, when the end confirmation time has not elapsed, the camera device 20 returns to step S110 of FIG. 11 to analyze the image data by the image analysis unit 203, and detects the moving body image in step S111 of FIG. The operation of determining whether or not it is repeated.

Then, when the moving image is not detected during the end confirmation time, the camera device 20 proceeds to step S119 of FIG. 11, ends the analysis of the image data, and ends the operation.

As a result, the camera device 20 does not analyze the image data in the image analysis unit 203, so that, for example, when a worker of the sales office 110 enters the shipping cargo receiving room 111 from the office 112, the visitor visits. When a person does not enter through the door 113, detection of the moving body image of the shipment receiving room 111 and generation of recorded image data are stopped. Therefore, generation of unnecessary recorded image data can be eliminated.

Further, when the camera device 20 detects a moving image while repeatedly executing steps S110, S111, and S118 of FIG. 11 after the lapse of a predetermined time and before the lapse of the end confirmation time, when the camera device 20 detects the moving object image, step S112 is performed. Then, the process proceeds to step S<b>2 to generate a moving body image detection alarm signal and recorded image data, and transmit them to the communication device 26 and the server 40.

Thereby, for example, the behavior during the period when the delivery company 60 stays in the shipment receiving room 111 can be surely recorded.

As described above, even when the visitor stays in the shipment receiving room 111 for a long time, the entry/exit management system 101 uses the image data during the period in which the visitor stays in the shipping receiving room 111 as a recorded image. It can be output to the server 40 and transmitted to the user's mobile terminal 50. As a result, security can be improved. If no moving image is detected before the end confirmation time, the analysis of the image data ends, so the image of the shipment receiving room 111 when the visitor is not entering through the door 113 is recorded as image data on the server. No output to 40. In this way, the entrance/exit management system 101 can output the image of the shipping receiving room 111 as a recorded image to the server 40 according to the visitor's staying time in the shipping receiving room 111, and unnecessary images can be output to the server 40. It is possible to prevent the output from being output to, and it is possible to efficiently manage entry/exit.

Next, another operation process of the entry/exit management systems 100 and 101 shown in FIG. 1 will be described with reference to FIG. This operation process is an operation of transmitting the browsed image to the mobile terminal 50 when the user of the entry/exit management system 100 or 101 designates the time with the mobile terminal 50 to request the browse of the image captured by the camera 21. ..

As shown in FIG. 13, the user of the entry/exit management system 100, 101 accesses the server 40 from the portable terminal 50 and inputs a browse image request for requesting the browse of an image at a specified time. Then, as shown in FIG. 13, the server 40 sends a browsing image request including the designated time to the communication device 26. The communication device 26 that receives the request transmits the browse image request to the camera device 20. The camera device 20 that has received the browse image request uses the image data stored in the first memory 24 as image data for the set time before and after the designated time included in the browse image request as the browse image data. 25, and transmits from the communication device 26 to the server 40. The server 40 stores the received browsing image data in the image data storage unit 43 and transmits the browsing image data to the user's mobile terminal 50. The user can receive the transmitted browsing image data and browse a moving image for a set time before and after the time designated by the mobile terminal 50 from a remote location.

As a result, the user can remotely view the videos for the set time before and after the time specified by the mobile terminal 50, and can confirm the state of the shipment receiving room 111 of the sales office 110 at any time. it can.
