When the lock opening / closing means 44 receives an instruction signal for unlocking the lock of the door from the server 9 via the communication line 8, the lock opening / closing means 44 releases the door lock so that the room can be entered.
This prevents entry of persons who do not have the IC card 4 such as third parties other than employees.

Next, the processing procedure of the video surveillance system according to the embodiment of the present invention will be described based on the flowchart shown in FIG.
First, when the user enters the room 1, the user brings the IC card 3 that he / she has close to the card reader 11 for entry, and is stored in the IC card 3 by the IC card reader 11 for entry. Specific information such as employee ID is read. (Step S1)
The IC card reader 11 for entering the room transmits the read employee ID to the server 9 via the communication line 8. (Step S2)

Then, the server 9 performs authentication processing for the received employee ID. (Step S3)
In this authentication process, it is determined whether or not entry is permitted from the employee information registered in the employee information database 39, and when the entry authentication is permitted, the server 9 sends the lock management apparatus 10 to the lock management apparatus 10. On the other hand, a signal for instructing unlocking is transmitted via the communication line 8. (Step S4)
Thereby, the lock | rock of the locking management apparatus 10 is cancelled | released and it can enter from an opening / closing door. (Step S5)

Next, when a user who has entered the room 1 uses the personal computer 2a that is always used by the user, the user first puts the user into the IC card reader 5 provided in the personal computer 2a. The IC card 3 possessed is brought closer, and the employee ID stored in the IC card 3 is read by the IC card reader 5. (Step S6)
The IC card reader 5 transmits the read employee ID to the server 9 via the communication line 8. (Step S7)

Then, the server 9 performs authentication processing for the received employee ID. (Step S8)
When authentication is permitted, a signal instructing unlocking is transmitted from the server 9 to the personal computer 2a via the communication line 8. (Step S9)
As a result, the user 6 can work using the personal computer 2a.

Thereafter, it is assumed that the user 6 leaves his / her seat to use the copier 2b or the printer 2c as necessary.
When the user uses the copier 2b or the printer 2c, the IC card 3 possessed by the user is brought close to the IC card reader 5 provided in the copier 2b or the printer 2c. The employee ID stored in the IC card 3 is read by the card reader 5. (Step S10)
The IC card reader 5 transmits the read employee ID to the server 9 via the communication line 8. (Step S11)

Then, the server 9 performs authentication processing for the received employee ID. (Step S12)
When authentication is permitted, a signal instructing unlocking is transmitted from the server 9 to the copy machine 2b and the printer 2c via the communication line 8. (Step S13)
Further, the server 9 receives an employee ID from the copier 2b or the printer 2c, which is an electronic device other than the personal computer 2a, which is an electronic device that is always used by the employee, or an IC card reader 11 for entering or leaving. When the employee ID is received from the employee information registered in the employee information database 39 shown in FIG. 4, the monitoring camera device 3 of the camera number registered in association with the received employee ID is selected. Then, a shooting start instruction signal for starting shooting is transmitted. (Step S14)

The monitoring camera device 3 that has received the shooting start instruction signal performs shooting for a time set in the storage unit 28 in advance. (Step S15)
The monitoring camera device 3 transmits the video information to the server 9. (Step S16)
Then, the server 9 registers the video information received from the monitoring camera device 3 in the video information database 38 in association with the employee ID. (Step S17)
Through the above processing, the computer 2a that is always used by the employee who is the user is systemized so that even if the employee leaves the seat, the computer 2a can be photographed to see if it is being used by another person. ing.

Next, the outline of the configuration of the video monitoring system according to the second embodiment of the present invention will be described with reference to FIG.
FIG. 7 shows a room 1a in which a personal computer 2a that is constantly used by employees who are users is installed and another room 1b such as a conference room.
The entrance doors 7a and 7b of the respective rooms are provided with IC card readers 11a and 11b for entry and IC card readers 11c and 11d for exit.
When the user 6 enters or leaves the room, the user 6 reads the employee ID by bringing the IC card 4 close to the IC card readers 11a and 11b for entering or the IC card readers 11c and 11d for leaving. Then, each IC card reader transmits an employee ID to the server 9 to perform authentication processing, and from the employee information registered in the employee information database 39, the camera registered in association with the received employee ID. An imaging start instruction signal for starting imaging is transmitted to the numbered monitoring camera device 3.

The monitoring camera device 3 that has received the shooting start instruction signal performs shooting for a time set in the storage unit 28 in advance.
The monitoring camera device 3 transmits the video information to the server 9, and the server 9 registers the video information received from the monitoring camera device 3 in the video information database 38 in association with the employee ID.
By the above processing, even when the employee who is the user uses a room such as a conference room, the personal computer 2a which is always used can be systematized so that it can be photographed whether another person is using it. Yes.
