  The radio unit 24 includes a base station communication unit and a GPS reception unit, and is a communication unit that communicates with other communication devices. The base station communication unit is a mobile communication unit that performs wireless communication with the mobile communication base station 16, and the communication device 2 is monitored by the base station communication unit via the mobile communication base station 16 and the communication network 8. Communication with the center device 6 of the center 14 is possible.

The position information acquisition unit 26 periodically measures the current position of the communication device 2. For this purpose, the position information acquisition unit 26 includes, for example, a GPS receiver that receives a signal from a GPS satellite, and has a function of measuring the latitude and longitude of the current position of the communication device 2 based on the received signal. ing.

  The operation unit 28 is an input means for the security guard 10 as a user to select an operation of the communication device 2 and to give an instruction to the control unit 20, and includes, for example, various button switches and a touch panel.

  The camera 30 is an imaging unit that images a subject such as a person or a landscape. The microphone 32 is a sound collection unit that collects the voice of the guard 10 during voice communication or the like. The speaker 34 is a voice output unit that outputs the voice of the other party during voice communication, or outputs a ringing tone when an incoming call is received or an e-mail is received. The display unit 36 is image display means such as a liquid crystal display.

  The wireless unit 24, the position information acquisition unit 26, the operation unit 28, the camera 30, the microphone 32, the speaker 34, and the display unit 36 are connected to the control unit 20 and operate by receiving signals from the control unit 20. To output a signal.

  The control unit 20 is configured using a microprocessor or the like, and performs various processes according to a program to be executed. For example, the control unit 20 includes a communication control unit 40, a position determination unit 42, a mode setting unit 44, a camera control unit 46, and an image data protection unit 48.

  The communication control unit 40 constitutes a communication unit that performs a voice communication function and an Internet connection function together with the wireless unit 24. Specifically, in voice communication, a line connection is established with the communication device of the other party, and the voice signal converted into an electric signal by the microphone 32 is input to the radio unit 24 via the communication control unit 40. The radio unit 24 converts the radio signal into a radio signal and transmits the radio signal to the mobile communication base station 16. The radio signal received from the mobile communication base station 16 is detected by the radio unit 24, and the extracted audio signal is input to the speaker 34 via the communication control unit 40 and the audio output circuit.

  The position determination unit 42 compares the current position information acquired by the position information acquisition unit 26 with the permitted position information 52 stored in the storage unit 22. Then, the position determination unit 42 determines that the restriction should be removed when the current position of the communication device 2 is the permitted position. Note that the position determination unit 42 may determine that the restriction should be released when the current position of the communication device 2 is within a predetermined range of the permitted position (for example, within a radius of 10 m). This predetermined range may be set individually according to the area of the building and facility set as the permitted position.

Further, when the position information (or identification information) of the guard's vehicle is stored as the permitted position information, the position information of the vehicle is acquired via the monitoring center 14 and the current position of the guard's communication device 2 is obtained. The vehicle position information may be compared to determine whether the restriction should be removed. The vehicle position information can be obtained by mounting a communication device having a GPS function on the vehicle, and the restriction should be lifted based on the communication result by the short-range communication between the guard communication device 2 and the vehicle communication device. It may be determined.

  The mode setting unit 44 controls the imaging unit to set a mode for whether or not the security guard 10 can shoot. There are two types of modes to be set, one is a restriction mode that restricts photographing, and the other is a release mode that permits photography by releasing the restriction. The mode setting unit 44 is normally set to a restriction mode that restricts photographing by the imaging unit, and when the position determination unit 42 determines that the current position of the communication device 2 is a permitted position, the mode setting unit 44 enters a release mode in which the photographing can be performed. Switch. In this embodiment, the position is determined every predetermined time by switching to the release mode, and when the current position is no longer the permitted position, the limit mode is restored. In the restriction mode, for example, the camera control unit 46 prohibits the activation of the application program itself of the camera function, or it is possible to capture the input image, but prohibits saving the captured image information in the storage unit 22. To do.

The camera control unit 46 constitutes an imaging unit together with the camera 30 and controls the operation of the camera 30. For example, when the security guard 10 activates the camera function from the operation unit 28, the camera control unit 46 drives the solid-state imaging device constituting the camera 30 to capture an image, takes an image signal from the camera 30, and inputs the input image to the display unit 36. Is displayed. When the shutter operation is performed, the camera control unit 46 captures the input image, and when the storage operation is performed, the captured image information is written in the image data 56 of the storage unit 22.

  The image data protection unit 48 prevents the security guard 10 from operating the communication device 2 to delete the image information captured by the camera 30 from the image data 56 in the storage unit 22 or copying it to another recording medium. To do. Further, the image data protection unit 48 prohibits attaching image information to a transmission mail to a destination other than a preset transmission destination. Note that the communication device 2 can be configured to automatically send a photographed image to the center device 6 by mail, and in this configuration, the center device 6 is set in the communication device 2 as a transmission destination that is permitted to transmit image information. .

  The storage unit 22 is realized by a memory device such as a ROM (Read Only Memory) or a RAM (Random Access Memory), and stores various programs executed by the control unit 20 and necessary data. In particular, in the storage unit 22, information on a position where the restriction is to be released (permitted position information 52) and center device address information 54 are registered in advance.

The permitted position information 52 includes, for example, the office to which the security guard 10 belongs, the car on which the security guard 10 rides, the property that the security guard 10 should visit (or the property that the security guard 10 should deal with), and the like. Each latitude and longitude, or address name is stored in association with the identification number or name. Or, when an abnormality occurs in a facility or mansion (hereinafter referred to as a property) to be monitored, when the security guard 10 to be dealt with is designated at the monitoring center, the communication device 2 of the security guard 10 The position information of the property is transmitted as permitted position information and stored in the storage unit 22 of the communication device 2.
