0 is a list as a list describing the priorities of mobile phones. In the present embodiment, only the method of creating the list 30 is different from that of the first embodiment, and only the point will be described.

First, a description will be given with reference to FIG. First, parameters for determining priority (n as a variable), such as vacation (a as a variable) and business trip (b as a variable)
Suppose that one is used. It should be noted that the value of a = 1 is entered when taking a vacation, and the value of b = 1 is entered when traveling. Next, the priority of a teacher whose at least one of the variable a and the variable b is 1 (teacher B and teacher C in the figure) is set lower than the other teachers. As described in step S20, the school terminal 1
No. 2 tries a call from the priority n = 1, that is, a teacher who is on vacation or on a business trip will be less likely to receive a call. That is, teachers who are on vacation or on business trips cannot immediately go to the site when pressing the button and can take action, so lower the priority in advance and set as much as possible to prevent calls. deep.

Next, a description will be given based on FIG. First, a parameter for determining a priority order (n as a variable) and position information of a mobile phone (a as a variable) are used. Next, position information indicating the current position of each teacher's mobile phone is obtained from a mobile phone company through a general telephone line. Next, based on the acquired position information, according to the distance from the school where the safety zone monitoring device 1 is installed, a value is set to the variable a of each teacher so that the variable a increases as the distance increases. Of course,
You can put the distance directly. Next, priorities are assigned in ascending order of the variable a. That is, the priorities are assigned in order from the closest to the school.

Note that the position information of each mobile phone may be acquired periodically and the list 30 may be updated periodically. In the present embodiment, vacation, business trip, and location information of the mobile phone are used as factors for determining the priority order. However, the present invention is not particularly limited to these factors, and may be changed as needed. I do not care. Note that the present embodiment is merely an example of the list 30, and is not limited to the above-described list 30. That is, what kind of list 30 is used if differentiation is made among a plurality of mobile terminals by priority.
May be in any form, such as the configuration of the program and the method of determining the priority.

The list 3 of the priority order in the school terminal 12
Although 0 is managed, it is not particularly limited.

As described above, in addition to the effects of the first embodiment, the security device according to the present embodiment changes the priority order according to the situation of each teacher having a mobile phone, and is therefore called in an emergency. The teacher who can respond quickly in case of a call can be given priority.

Embodiment 3 In the present embodiment, portions denoted by the same reference numerals as those in Embodiment 1 indicate the same or corresponding portions. In the present embodiment, only the steps S14 and S20 in the first embodiment are different, and only the points and the points accompanying the points will be described.

Next, the operation will be described. First, in the first embodiment, a configuration is adopted in which a still image is confirmed from a mobile phone through a homepage using the mobile phone. In the present embodiment, a configuration is adopted in which a still image is attached to a mail and confirmed. Therefore, it is assumed that a mobile communication terminal capable of receiving and browsing an image attached to an e-mail is used instead of the mobile phone in the first embodiment.

Next, the operation of the center facility 10 will be described. FIG. 8 is a flowchart showing the operation of the center facility 10, and description will be made based on this flowchart. First, all devices are started. Next, step S14
The steps up to this point are the same as in the first embodiment, and will not be described.

Next, in step S14, the camera control device 1
1 receives the still image when the button is pressed transmitted from the front camera 4 and transfers it to the school terminal 12. Further, in order to transmit the still image to the mobile phone 22, the school terminal 12 converts the still image into specific image data, and then proceeds to step S14.

Next, steps S15 to S20 are the same as those in the first embodiment, and therefore will not be described.

Next, in step S21, the school terminal 12 notifies the talkable portable telephone 22 by voice synthesis that informs the user that the HELP button 6 of the safety zone monitoring device 1 has been pressed. You sent a notification like At the same time, step S14
A still image changed to a specific image format is also transmitted.
Move to step S22.

Step S22 and subsequent steps are the same as in the first embodiment, and will not be described.

Next, the operation of the portable communication terminal will be described. Note that the mobile communication terminal uses a commonly used one and does not perform an operation unique to the present application. Therefore, an operation using the mobile communication terminal will be described. The operation is almost the same as the operation of the mobile phone described in the first embodiment. However, as described above, in the present embodiment, a still image is attached to an e-mail for delivery, so that step S32 is omitted. That is, in step S31, an e-mail with a still image attached thereto is sent together with the call, and is sent to step S3.
It is sufficient to confirm in 3. The rest is the same as in the first embodiment, and will not be described.

The list 30 used in the second embodiment can be applied to the present embodiment. The electronic mail may be transmitted after being encrypted. At this time, any encryption method such as secret key encryption and public key encryption may be used.

As described above, in the security device according to the present embodiment, in addition to the effects of the first embodiment, in the present embodiment, a notification is given by attaching a still image at the time of pressing a button to a mail. Host computer 2
There is no need to connect to 0, and it is possible to respond more quickly. Also, since there is no need to explain the homepage via a provider, it is possible to reduce labor and cost. Also, since there is no need to go through a third party such as a provider, privacy is ensured. Further, since the e-mail is transmitted after being encrypted, security can be reliably ensured.

In each embodiment, a plurality of safety zone monitoring devices may be provided. Further, only the HELP button may be dispersed and installed in the safety zone so that the HELP button can be started immediately in an emergency.
