It can be recorded in 2.

A personal computer 12 with a surveillance camera 13 is connected to the receiving / storing means 24, and the input information of the visitor transmitted from the personal computer 12 (company name, name, registration number of visitor). , Name of visit destination) and image information of the captured surveillance camera 13 can be received and held. A monitor television 25 is connected to the receiving / storing means 24 so that a guard can immediately confirm the received information. At the same time, these pieces of information are sent to the transmitting means 26 and transferred via the public telephone network 15 to the mobile telephone 16 capable of displaying an image possessed by the employee.

Next, the monitoring operation by the outsider monitoring system 20 having the above configuration will be described with reference to FIGS. 4 and 5.

FIG. 4 is a monitoring sequence of an employee who possesses the dedicated tag 11. As shown in FIG. 4, when the employee passes through the first gate 5 to enter the room, first, the first sensor 7 is detected (S30), and the detection information is sent to the determination means 23 of the monitoring device 21. Judgment means 23
Recognizes that the passerby 10 exists at the first gate 5 based on this detection information. Next, when the third sensor 9 is detected (S31), the passerby 10 is recognized as an employee, and when the second sensor 8 is subsequently detected (S32), the employee enters the room. It recognizes that it has done (S33). Conversely, when the employee leaves the room, the second sensor 8 is detected (S34), then the third sensor 9 is detected (S35), and then the first sensor 7 (S36).
By the detection of "," the determination means 23 recognizes that the employee has left the room (S37).

Since this series of operations is a normal entry / exit, the alarming means 14 and the second gate 3 are not locked. Therefore, a smooth entry / exit is ensured for the workers, and the monitoring system does not impair the convenience of the workers in their daily work.
In this series of entering / leaving operation, the judging means 23 detects the entering time and the leaving time of the worker based on the detection timings of the second sensor 8 and the first sensor 7, and records the respective time data in the entering / leaving time recording means 22. It is also possible to save the data in S. (S38, S39) and use it later as data for grasping the work status of the worker.

Next, a monitoring sequence for an outsider who does not have the dedicated tag 11 will be described with reference to FIG.

Sent. The determination unit 23 recognizes that the passerby 10 exists at the first gate 5 based on the detection information.
However, next, unlike the case described above, when the second sensor 8 is detected without detecting the third sensor 9 (S41) (S42), the determining unit 23 determines that the passerby is an outsider. It is determined that the outsider has entered the office 2 without permission (S43). At this time, the determination unit 23 detects the entry time from the detection information of the second sensor 8 and stores the time data at that time in the entry / exit time recording unit 22 (S4).
4) The alarm means 14 is notified, an alarm buzzer is sounded, an alarm is displayed to intimidate an outsider, and an exit recommendation is broadcast. At the same time, the alarm information is transferred to the mobile phone of the employee in charge.

Particularly at night when there are few office workers, when an outsider's unauthorized entry is recognized, the alarming operation is triggered by the above alarm, and the door 4 with the electric lock of the second gate 3 is automatically locked to notify the alarm target person. Can be contained within the facility to prevent the act of getting out of the facility. With such a crime prevention operation, sufficient security management can be achieved even at night.

When the above-mentioned alarm is issued, the outsider follows his / her instruction on the screen from the personal computer 12 installed in the vicinity of the second gate 3, and his / her company name, name, and registration number (the outsider related to the work is specified in advance). (Register the registration number of) and input the name and the like of the visited place (S47). At this time, the surveillance camera 13 is simultaneously picking up an image of the person who inputs to the personal computer, and the image data thereof is sequentially taken into the personal computer 12. These input information and image information are received by the monitoring device 20 from the personal computer 12.
The data is sequentially transferred to the storage means 24 and displayed on the television monitor 25, and the work means (for example, the person in charge of business who matches the registration number of the outsider or the name of the visited person) from the transmission means 26 via the public telephone network 15. Person's mobile phone 16 is automatically transferred. The person in charge of business quickly recognizes the visit of an outsider from various input information and images displayed on the mobile phone 16 and unlocks the door 4 with the electric lock of the second gate 3 which is locked by remote control as needed. It can be locked (S48). Further, the guard in the guard room can unlock the door 4 with the electric lock by confirming the outsider from the monitor information on the TV monitor 25 (S48).

In this way, the employee can immediately know the visit of the outsider at any time and anywhere, and the employee in charge goes to the first gate 5 each time to respond to the visitor, as in the conventional case. It is free from the hassle of doing.

When an outsider leaves the room, the second sensor 8 detects (S50) to the third sensor 9 does not detect (S5).
The exit of an outsider is recognized based on the sensor information of 1) to the detection of the first sensor 7 (S52) (S54). At this time, the determination means 23 detects the leaving time of the outsider from the detection information of the first sensor 7, and holds the time data in the entering / leaving time recording means 22 (S53). In this way, by recording the entry / exit time data of an outsider in a record, it is possible to help strengthen security management in the future.

As described above, in the embodiment, the third sensor 9 for identifying the passerby 10 is installed between the first sensor 7 and the second sensor 8 for detecting the presence of the passerby 10. However, the third sensor 9 may be installed at any place where the dedicated tag 11 of the passerby 10 can be detected. In addition, the sensor for detecting the passerby 10 is not limited to the two sensors of the first sensor 7 and the second sensor 8 as in the present embodiment.
The point is that two or more sensors may be installed along the passage direction of the first gate 5 so that the moving direction of the passerby 10 can be recognized, and the number and installation position of the sensors are not limited.
