The recording medium may be, for example, a hard disk drive (HDD) or a digital versatile disc (DVD), and a video file can be stored in the cloud server 12 in a large capacity.

The monitor 19 displays the decoded moving picture file so as to be visually recognizable. The moving images taken by the four channels of the security cameras 22, 24, 26 and 28 may be displayed on different channel screens of the monitor 19 or may be displayed in quadrant on one channel screen. The security officer can watch the area of interest photographed by the security cameras 22, 24, 26, 28 by watching the screen of the monitor 19 in real time. When the security officer views the screen of the monitor 19 and judges that a security-related event has occurred, the user can immediately take appropriate measures. For example, you can contact the security officer or the police patrolling the area, contact 119 if a casualty has occurred, and contact the fire department if a fire occurs. If the judging unit 41 judges that it is in an emergency situation, an alarm (not shown) may be activated in the control room or the monitor 19 May be configured to blink in red.

3 is a plan view showing an example of a screen displayed on the front side of the portable communication device of FIG. 1 when an incident occurs. 2 and 3, the portable communication device 14 receives and displays a moving image transmitted from the wireless communication unit 54 using wireless communication. The portable communication device 14 may be a smart phone, for example, and may transmit a moving picture through the 8080 TCP port. This enables the smartphone to be used as a remote monitoring interface for monitoring events at a remote site. The user of the portable communication device 14 may be a security officer working in the situation room.

Specifically, for example, an application capable of receiving and reproducing a moving image transmitted through the wireless communication unit 54 is installed in the portable communication device 14, and it is determined that an event causing a security problem has occurred The application 41 can be set to automatically execute the installed application. Then, when an event occurs, a screen as shown in FIG. 3 is popped up with a strong vibration or a ring tone, so that a moving picture relating to a situation at an event occurrence point can be grasped in real time from a remote place. A pop-up screen can be displayed by dividing a moving picture photographed by one to four security cameras 22, 24, 26, and 28 into four. However, the screen of Fig. 3 is merely an example, and various other examples are possible.

On the other hand, the user of the portable communication device 14 not only waits for the application screen to be automatically popped up but also executes the application directly to display a moving picture photographed by one to four channel security cameras 22, 24, 26, So that the same effect as monitoring the area of interest through the monitor 19 (see FIG. 1) can be obtained in the situation room even though the user is absent from the situation room.
