SOLUTION: When a visitor is a person who visits for the first time, a computer adds information for identifying him at next call to a data base, and then when the visitor and a resident who is absent are not able to make a conversation in a real time, the computer retrieves the data base, and records the business by automatically answering at the time of judging that the visitor is the acquaintance of the resident who is absent.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a home security system for connecting an intercom and a telephone line via a computer.

[0002]

2. Description of the Related Art As a prior art, Japanese Patent Application Laid-Open No. 11-220
As described in Japanese Patent Publication No. 544, when there is a visitor in an answering machine, an intercom and a telephone line are connected so that a call can be made in real time between the visitor and an outsider. Intercom answering devices are known. Further, according to the present intercom answering apparatus, even when a visitor and a visitor cannot respond in real time, after the visitor returns home, it is possible to at least know the business and the presence or absence of the visitor.

[0003]

However, in the above prior art, since the function does not operate unless the doorbell button of the intercom is pressed, it is impossible to record a suspicious person wandering in front of the entrance to the absence or at the entrance. There was a security problem.

[0004] Further, since it is not known whether there is a visitor to an absence house or a business until returning to home, if the house is left for a few days, if a call cannot be made in real time, until the business of the visitor returns home. There was a problem that it could lead to some loss without understanding.

The present invention solves the above-mentioned problems and deficiencies of the prior art. When a visitor is an acquaintance and a real-time conversation is not established, a message is reliably recorded. It is an object of the present invention to provide a home security system which includes an automatic response means for allowing a user to know information of a visitor from outside while being out.

[0006]

In order to achieve the above object, in the home security system of the present invention, by adding a visitor detection device to the intercom, the intercom can be installed even if the doorbell button is not pressed. Suspicious persons who roam at the entrance or in front of the entrance can be recorded. If no real-time conversation is established between the visitor and the visitor, it is determined whether the visitor is an acquaintance or not, and if so, the computer automatically responds and records the message. It is something that can be done. Further, the out-of-home visitor can always know the presence or absence of the visitor, the visitor and the business by connecting the line from the portable terminal to the computer through the telephone device of the answering machine.

According to the first aspect of the present invention, an infrared sensor is added as a visitor detecting device to a part of the intercom, and the infrared sensor detects a suspicious person who roams in front of the entrance or the gate even if the doorbell button is not pressed. By starting the computer, the image and sound of the suspicious individual and the time when the suspicious individual visited can be recorded, and the crime prevention effect can be enhanced. Also, basically, when there is no visitor or after the visitor leaves, only the infrared sensor needs to be operating, and by saving other systems except the infrared sensor in the power saving state, power saving can be achieved. The effect can also be enhanced.

According to a second aspect of the present invention, by detecting that the doorbell button has been pressed, the computer notifies the preset portable terminal of the presence of the visitor through the telephone line for the first time, and the line between the computer and the portable terminal. Is established, the computer connects the intercom line to the telephone device and transfers the image from the CCD camera and the sound from the microphone to the portable terminal, but does not output the sound from the portable terminal to the Only when a connection permission signal between the microphone of the portable terminal and the speaker is received from the terminal, the sound from the portable terminal is output to the speaker. If the person who pushed the doorbell is not an acquaintance, unless the outsider sends a connection permission signal, it is unnecessary to guess the absence of the outsider and the current position of the outsider from the noise around the outsider, and the security effect Can be increased.

According to the third aspect of the present invention, if a line between the computer and the portable terminal cannot be established when notifying the presence of the visitor, the computer has visited the visitor once in the past. Check with a previously created database to see if it is a person. As a collation method, the features of the visitor's face and eyes are extracted from the image from the CCD camera, and whether or not there is a matching person on the database. Whether the doorbell button has a fingerprint recognition function and the same fingerprint data is recorded in the database. If the visitor claims his name, whether the same name is recorded in the database by the speech recognition system. Also,
Whether the voice recognition data matches the voiceprint data on the database by the voice recognition system is mentioned. The determination as to whether or not the person is an acquaintance of an out-of-home person is performed by any of the above-described collation methods or a combination of a plurality of methods. Only when it is determined that the person is an acquaintance of a person who has gone out, and only if the person has been set to allow automatic responses in advance by the person outside, by responding with a message saying that he / she is currently out and about his / her business Thus, the effect of reliably recording the visitor's requirements can be obtained.

According to a fourth aspect of the present invention, when a line between the computer and the portable terminal cannot be established when notifying the presence of a visitor, the computer is started up at predetermined time intervals using a built-in timer, and is set in advance. Attempt to notify the mobile terminal of the presence of the visitor through the telephone line, and if the line is established, transfer the image, sound, and the time of the visitor to the mobile terminal according to the instruction from the mobile terminal. If the line cannot be established, the time at the next start-up is set in the built-in timer of the computer, and the computer returns to the original power saving state.

According to a fifth aspect of the present invention, the computer is activated from a power saving state by a signal indicating that a call is received from the portable terminal to the telephone device, and in accordance with an instruction from the portable terminal, the presence or absence of a visitor, If there is, the image, sound and the time of the visitor are transferred to the portable terminal, and after the telephone line is disconnected, the state returns to the original power saving state.
