The monitoring system of FIG. 1 displays two personal computers 2 (hereinafter referred to as PCs) as monitoring targets and signs of fraudulent behavior of the PC 2. It is composed of a plurality (two in this case) of monitoring cameras 1 having a function of capturing the PC 2 on which a sign of fraud has occurred.

  In the future, when it is desired to clearly distinguish the two PCs 2 from each other, the right side PC 2 in FIG. 1 is denoted as PC 2_1, and the left side PC 2 is denoted as PC 2_2. Similarly, when it is desired to clearly distinguish the two monitoring cameras 1, the right monitoring camera 1 is referred to as a monitoring camera 1_1 and the left monitoring camera 1 is referred to as a monitoring camera 1_2 in FIG.

  FIG. 1A is a diagram when no sign of cheating has occurred in any of the two PCs 1. When no sign of cheating has occurred, the surveillance camera 1_1 photographs the PC 2_1, The monitoring camera 1_2 takes a picture of the PC 2_2.

  FIG. 1B is a diagram after a sign of fraudulent activity has occurred on the PC 2_1. For example, when the user authentication of the user using the PC 2_1 fails, the two surveillance cameras 1 have a sign of fraudulent action on the PC 2_1. When it is detected that the occurrence has occurred, the two surveillance cameras 1 focus on the PC 2_1 so as to be able to quickly analyze when an illegal act occurs.

  As shown in FIGS. 1 (a) and 1 (b), by changing the photographing conditions such as the area, magnification, and number of pixels that each surveillance camera 1 shoots before and after the sign of fraud occurs. It is possible to take a clear picture of the situation when fraud occurs.

  FIG. 2 is a block diagram of the monitoring system shown in FIG. As shown in FIG. 2, each surveillance camera 1 and the PC 2 to be monitored by the surveillance camera 1 are connected via a network 3 (here, LAN), and an event indicating a sign of fraud occurs on the PC 2 Then, an event code indicating the event that has occurred is transmitted from the PC 2 to the monitoring camera 1 via the network 3.

  In the present embodiment, the PC 2 includes a user authentication unit 20 that authenticates a user who uses the PC 2 as an event detection unit that detects an event indicating a sign of fraud. The type of user authentication performed by the user authentication means 20 provided in the PC 2 is not limited, and a method using a password or a method using user biometric information (fingerprint information or the like) may be used.

  The user authentication means 20 of the PC 2 detects failure of user authentication as an event indicating a sign of fraud, and when user authentication fails, an event code indicating failure of user authentication and ID information for identifying the PC 2 (For example, an IP address or a MAC address) is transmitted to the monitoring camera 1.

  The monitoring camera 1 includes a CCD camera 11 that captures the PC 2 to be monitored, a video storage unit 12 for storing video captured by the CCD camera 11, and an event code transmitted from the PC 2 to be monitored.
