[0020]
This indoor base unit 30 distributes a line interface 41 that transmits and receives a signal modulated / demodulated by a modem via a telephone line N1 connected by a network control device to another system by amplifiers 42 and 43 and a 2-wire to 4-wire conversion circuit 44. The control unit 31 performs an input control to input the setting input unit 45 to read the telephone number of the mobile phone T set in advance in the setting storage unit 46 and make a call by the transmission unit 47, By receiving a call from an external terminal such as the mobile phone T and controlling incoming calls, the microphone 15 and the speaker 16 of the entrance cordless handset 10 are connected so that a call can be made.
[0021]
The indoor base unit 30 stores the telephone number, user ID, and password of the ISP 200 for dial-up connection to the contracted ISP 200 in the setting storage unit 46, and transmits an e-mail as will be described later. A mail address such as the mobile phone T as a destination and a time interval for delaying the start of an operation for automatically establishing a call between the front door 10 and the mobile phone T are stored in the setting storage unit 46. When the absence mode is selected and set and the call is made by the visitor, the control unit 31 confirms the visitor's video from the mobile phone T and makes a doorphone call with the front door 10. Can be done.
[0022]
Specifically, as shown in FIG. 4, when the call switch 11 is pushed by a visitor, the front door 10 receives the video signal captured by the camera 13 together with the call signal from the call control circuit 12 to the indoor base unit 30. Send it out.
[0023]
At this time, when the absence mode is selected and set in the indoor parent device 30, and the call detection circuit 48 detects the calling signal from the entrance child device 10, the control unit 31 converts the video of the visitor into the GIF format. While being stored in the video storage unit 39, the telephone number, user ID and password in the setting storage unit 46 are read out and dial-up connected to the ISP 200 via the telephone line network.
[0024]
Subsequently, the control unit 31 uses the IP address that is sent from the ISP 200 by the dial-up connection for the video of the visitor stored in the video storage unit 39 while maintaining the dial-up connection. This makes it possible to browse from an external terminal via the Internet N2, and creates an e-mail in which the acquired IP address is attached to a message of a visitor notification prepared in advance and is set as a destination in the setting storage unit 46 It is transmitted to the mail address of the telephone T.
[0025]
Therefore, the user who has received the e-mail sent to the mobile phone T and viewed the message of the visitor notification is a file on the Internet N2 specified by the IP address attached to the e-mail on the mobile phone T. For example, a URL (Uniform Resource Locator) connection is made to an information providing service center (for example, i-Mode center) 300 via a cellular phone line network, so that the IP address is given and dial-up connection is made. Can be instructed to browse the visitor video in the video storage unit 39.
[0026]
When the control unit 31 of the indoor base unit 30 detects access from the mobile phone T according to the browsing instruction, the control unit 31 transfers the GIF data of the visitor video in the video storage unit 39 to the request source (the mobile phone T). The mobile phone T can receive the GIF data and check the video of the visitor.
[0027]
Further, when the control unit 31 of the indoor parent device 30 simultaneously detects an access based on a viewing instruction of the visitor video in the video storage unit 39, the control unit 31 starts a timer function provided in the indoor parent device 30, as shown in FIG. In addition, after waiting until the timer value reaches the set time in the setting storage unit 46, the telephone number of the mobile phone T preset in the setting storage unit 46 is automatically dialed. In the telephone T, by responding to the call after confirming the video of the visitor, the communication path can be closed between the indoor parent device 30 and the indoor parent device 30 is connected to the entrance child device 10. By connecting the telephones so that they can communicate with each other, the user can make a doorphone call on the go even when the indoor base unit 30 is not installed. That is, the control unit 31 constitutes a mail transmission unit, an access unit, and a communication unit, and the setting storage unit 46 constitutes a time setting unit. You can make a doorphone call.
[0028]
As described above, in this embodiment, a light e-mail attached with an IP address assigned by dial-up connection to the ISP 200 while holding a video of a visitor in the video storage unit 39 of the indoor base unit 30 is sent to the mobile phone. The user can access the IP address attached to the e-mail from the mobile phone T and browse the video of the visitor held in the video storage unit 39 even when he / she is absent. It is possible to make a door phone call with the front door unit 10 only by answering a phone call after the access without performing a number input operation.
[0029]
At this time, the time from the access to the visitor's video to the automatic dialing to the mobile phone T can be arbitrarily set in the setting storage unit 46, so the visitor's video is confirmed and the automatic dial is answered. It is possible to secure a time for determining whether or not to do so, and when a visitor does not need to make a doorphone call, the mobile phone T can be turned off to make it unresponsive. .
[0030]
In addition, since the visitor video in the video storage unit 39 of the indoor base unit 30 can be accessed by the IP address, the IP address is manually input not only by the mobile phone T but also by a personal computer that can be connected to the Internet, for example. In addition, the e-mail destination and the telephone number to be automatically dialed can be arbitrarily set in the setting storage unit 46, so that the e-mail destination can be a personal computer, It is possible to set the other party to be automatically dialed according to the access to the customer video as a fixed telephone, depending on the convenience of the user.
[0031]
Therefore, a complicated operation is not required in order to respond to a visitor in the absence, and it is possible to easily and comfortably respond.
