Security and visitor communication system based on the Internet network and its method {The method and Security and visitor communication systems based on IP network}

The present invention relates to a security and visitor conversation system based on Voice over Internet Protocol (VoIP) and a method thereof, and when there is a visitor away from home, the conversation is not possible at all. However, this system enables real-time conversation with visitors and identification of visitors, enables remote business processes, and enables the intrusion to be detected in advance and prompt response, and general telephones. The present invention relates to a system and a method for providing a free telephone function by connecting.

Currently, many women are entering various fields of society due to the improvement of the status of women, and the family composition is made up of 3 to 4 people including parents per household due to the social atmosphere with a small number of children. . According to this situation, the number of working couples is increasing, and many social problems such as robbery (theft) occur due to the emptying of the house. . In addition, the demand for toll-free telephones is increasing as a part of reducing the burden of increased telecommunications rates in homes.

In order to cope with such a situation, a terminal is installed in the house by the service of a security-related company, and a service is provided to help in case of an intruder in the house, but installation and use fees are expensive. Functionally, it is impossible to communicate with visitors and is limited to detecting intruders and providing prompt assistance.

When a visitor comes to the house with a high-end video phone, there is a way to talk with the visitor while they are in the house. This method is meaningful only when there is a family member in the house. It's not possible and you can't protect your home from intruders.

In case of video memory video phone that can automatically record and preserve visitor's appearance and visit time in absence, it provides recording but can't talk while watching visitor's view in real time. This is a possible problem. In addition, there is a disadvantage that the price of the product is expensive because the memory is mounted in the video phone.

In addition, there are systems that notify the alarm room of abnormalities in the home or automatically call a predetermined place. These systems have a disadvantage in that additional communication costs for using the telephone network are additionally required because they are a communication method through a general telephone network.

Therefore, the present invention has been drawn in view of the problems of the prior art, the purpose of which is a system that enables a conversation while viewing the visitor in real time with the visitor who visited the house, as well as talking with the visitor in the house, even in the situation of starting data The present invention provides a visitor dialog system and a method for allowing a conversation through a video screen with a visitor through a network to handle household work even when the user is away from home.

Another object of the present invention is to protect the house from the intruder who wants to invade the house, the intruder presses the doorbell and at the same time the connection is made to the designated system, and tells that there is a person in the home through the conversation with the intruder, to secure the house from the intruder The present invention provides a security system and method for protecting the same.

In addition, if a visitor or intruder cannot talk in real time, the visitor and intruder's screens are automatically stored in a server on the network so that the server can be accessed immediately from where the server is accessible, rather than going home. The present invention provides a storage system and a method for verifying the identity through the business to greatly obtain the effect of business processing and crime prevention.

If you are unable to talk, you can notify your home phone or mobile phone in advance that there is a visitor or intruder in your home, or if you can't reach it this way, send a text message to your mobile phone automatically, or visit your PC. Periodically, it is notified until the confirmation, and to provide a notification system and a method for serving at a lower cost than using the existing PSTN network.

The present invention provides a transmission system and method for transmitting audio and video through a data packet network while communicating with a visitor or an intruder.

The present invention provides a free telephone system and a method for connecting free telephones to free telephones using a data network.

In order to achieve the above object, the present invention provides a step of notifying the visitor at the same time as the visitor presses the doorbell and automatically captures and transmits the visitor to the camera in real time when the visitor is in direct communication with the visitor. To communicate with the other party through a pre-recorded message, and to capture the visitor with the camera and send the video to a pre-designated server. IP network based on sending a message to inform the visitor that there is a visitor, and later, to know that the visitor was there, and to check the visitor through the visitor's video by connecting to the designated server to know who visited. Security and visitor dialogue system and methods thereof.

Define visitors and intruders as outsiders, and then mark them as outsiders. The overall structure of the security and visitor conversation system based on the IP network is shown in FIG.

Referring first to each element constituting Figure 1, the visit detection system 1 is composed of a camera, a microphone, a speaker is attached to the front door. When the outsider presses the doorbell, the outsider's screen and voice are transmitted to the network connection device 2, or the restored voice being transmitted through the IP network is output to the speaker so that the outsider can listen. Connected.

Network connection devices (2,4) are connected to the visit detection system (1) and the living room video phone (3) and enable data transmission / reception over the IP network. Responsible for restore / restore. It features software that lets you talk while viewing live screens, and a phone interface and stack to provide free phone functionality. It has a physical connection and TCP / IP stack for IP network connection. The living room video phone 3 has a bypass path for transmitting a picture and a voice.

The video / audio storage server 6 is a general desktop PC or workstation, which has a function of building a user's video and audio information and searching on the web, and is directly connected to the IP network. It is also equipped with an engine for building a user-specific database.

The designated PC 7 is a device which is connected to a network designated in advance by the user and connected to the Internet such as a general desktop PC and a workstation. It is a computer that is directly connected to the IP network, and when an outsider taps the doorbell, the connection request is automatically received. Microphones and speakers should be attached to enable conversation while viewing the screen.

When the outsider presses the doorbell, the first step of the present invention begins. The visit detection system 1 detects the presence of the outsider and a series of processes are performed. When the outsider is detected, the network connection device 2 notifies the living room video phone 3 or the designated designated PC 7 that there is an outsider. That is, it makes a connection request.

If there is a person in the house, the handset of the videophone can be held and a conversation with an outsider can be made through the visit detection system 1. At this time, the network connection device 2 performs a simple video and audio transmission function.

When leaving the house and in front of the designated PC 7, a connection request pop-up menu (Fig. 5) is displayed indicating that there is an outsider. The address of the designated PC 7 must be registered in the network connection device 2 before going out. When the connection is approved in this menu, the data path is set to the visit detection system (1), the network connection device (2), and the designated PC (7), and the conversation is possible while viewing the screen of the outsider and the outsider. Of course, outsiders can't see the screen, and can only talk by voice. At this time, data exchange is performed between the network connection device 2 and the designated PC 7 through the IP network.

Once the outsider presses the doorbell, it automatically connects to the video / audio storage server 6 through the visit detection system (1) and the network connection device (2) with the connection request. Stored. In this case, the transmitted video and audio also pass through the IP network.

The video and audio transmitted to the designated PC 7 and the video / audio storage server 6 are converted to digital by the network connection device 2 and converted into a predetermined compression format and transmitted.

Displayed in the living room video phone 3 is made only in the state of holding the handset of the video phone, the network connection device 2 is made in the analog state without undergoing digitization, compression conversion process. Therefore, the data transmission to the video phone is not made when you go out.

If the approval permission for the connection request is not made within the designated time in the designated PC 7, the designated PC 7 is considered to be incapable of conversation and the predefined normal telephone 8 is dialed. The call is not in the form of a direct call request through the PSTN network, but in the form of a VoIP method over the IP network and the PSTN network. The process of making a call attempts to connect to the telephone number registered in the network access device (2). Via the IP network, the connection is established via a telephone gateway located between the IP network and the PSTN network. Cheaper than the method used. If there is no acknowledgment of the connection request, the answering machine inputted in advance in the network connection device 2 operates, and an outsider simply confirms the identity and transmits the conversation contents and the outsider screen to the video / audio storage server 6. do.

If the designated PC 7 does not approve the connection request, it attempts to connect to the general telephone 8, but if the connection cannot be established, the telephone sequence is made to the registered cellular phone 9 in the next sequence. This also uses both the IP network and the PSTN network, not all of them. If there is no response from the mobile phone, a text message transmission server connected to the IP network automatically sends a text message indicating that there is an outsider.

In the situation of notifying by telephone, the presence of an outsider can also be notified to the general telephone 5 connected to the network connection device 4. This method means notification to the VoIP terminal.

In Fig. 1, the ordinary telephone 5 and the ordinary telephone 8 are connected to the IP network and are the same telephone with only the difference in the connection method connected to the PSTN network.

An example of the internal structure of the network connection device 2 of FIG. 1 is shown in FIG. The network connection device 2 is a terminal mounted at home together with a home sensing system 1 and a living room video phone 3 at home, and the video data input and audio data transmission (speaker) and input with the visit sensing system 1 are input. It has a (microphone) interface and bypasses video and audio data to the living room videophone, and is a key device for performing video and audio data exchange over an IP network.

The network connection device 2 has a video input unit 10 that receives an outsider's screen captured by the visit detection system 1 and a voice input / output interface for the microphone, speaker, and input / output interfaces of the visit detection system 1. Output unit 16, codecs 11 and 15 responsible for compressing and restoring video and audio data, WAN connection 14 providing a means of connecting to an IP network via high-speed Internet access, ADSL, Ethernet in WAN connection It has a cable modem interface function. The host processor is in charge of controlling the network connection device 2 and executing the program. The memory 13 temporarily stores video / audio data for compression and decompression. The telephone matching unit 12 is connected to a general telephone 5, and a free telephone is made through the telephone.

As the outsider presses the doorbell, the screen and sound of the outsider are stored in the video / audio storage server 6 through the IP network through the network connection device 2 for a predetermined time. The location of the storage server is registered in advance in the network connection device 2. The storage server 6 is a server that integrates and manages each user who uses the security and visitor chat system. This server 6 has the structure of FIG.

The video / audio storage server 6 determines the user once by examining each data packet coming into the server. The personal identification unit 17 responsible for the determination builds a database in accordance with the structure determined for each identified user. The data packet of which user discrimination is completed is sent to the DB classifier 18, classified into video and audio, and sent to each extractor 19 and 20, and constitutes the database 21 and 22. FIG. This configuration is made for each individual, and the number of users using the security and visitor conversation system exists.

The structures of the storage databases 21 and 22 are classified into video and audio. Video and audio are divided into four fields and have corresponding information. The file name is successively attached to an arbitrary name, and consists of a field indicating a date and time of reception, a field indicating size information of a stored file, and a field indicating whether a file is read or not. The database is web-accessible and includes editing features such as delete and copy. File names according to video and audio are given names indicating the characteristics of the database.

Fig. 5 shows a screen configuration pop-up upon connection request indicating that there is an outsider on the designated PC 7. Once (23), you can approve (yes) and decline (no) the connection that the outsider wants to connect. If the connection is approved, the outsider's screen is displayed on the video screen, and the conversation is possible while viewing the outsider's screen. Video and audio on / off control is done via the menu, defaults to audio, video on. Video / voice control is also available during conversations.

In order for the pop-up menu window to operate, the program daemon 24 for using the security and visitor dialog system must be operating in advance. In a situation where the program daemon 24 is not executed, even if a situation in which an outsider presses the doorbell occurs, the connection is not made. In this case, recording is automatically made to the video / audio server.

The free telephone function is to connect a general telephone 5 to the network connection devices 2 and 4 to transmit a voice packet through an IP network and to have a conversation. If the same network connection device is used, it can be used free of charge. . However, in order to talk with the general telephone 8 connected to the PSTN network, the user must pay the fee for using the PSTN network.

6 is an operation procedure diagram of the entire system, at step 25, the doorbell is pressed and at the same time proceeds to step 29, capturing the screen, and depending on whether the connection request is approved at step 27, the general telephone and Notify by mobile phone. If the connection request is approved, the conversation becomes possible while viewing the screen using the procedure (28). When the connection is terminated, the server storage of the screen is terminated.

As described above, in the present invention, even when the visitor is at home or at home, the visitor can talk in real time while watching the visitor.

In addition, the present invention can safely protect the house from intruders trying to invade the house, and even if the intrusion is made, it is possible to secure the identity through the image stored in the server in advance.

Even when you are on the move, you can quickly identify the presence of outsiders through mobile phone and general phone calls, and minimize the cost of contact by using the IP network.

Moreover, by connecting the network connection device (2) and the simple visit detection system (1), not only high-speed Internet access but also a free phone can be connected by connecting a regular phone and connected to a living room video phone to maximize the use of the existing video phone. It becomes possible.

By storing the screen and voice of outsiders on the server, the screen can be viewed through a direct connection wherever Internet access is possible, enabling faster work processing and information sharing.
