Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and method for transmitting video data and control data of a private network to the outside,

The present invention relates to a system and method for transmitting video data and control data of a network camera and network equipment in a private network, and more particularly to a system and method for transmitting video data and control data of a network camera and network equipment installed in a private network connected to public IP, , A client server installed in a network camera and a network device, and a relay server managing a plurality of client servers without a firewall, so that the transmitted image data and control data can be transmitted to the request device of the network camera user And a system for transmitting a signal commanded by a user of the network camera to the network camera through the relay server and the client server.

Until now, CCTV DVR or network camera, which is sold in the market, can transmit video data or control data only when it is set to allow data to be transmitted externally when it is connected to public IP basically or through setting on a router or a firewall Respectively.

If a user of a network camera receives a public IP and constructs a private network (usually a majority of users use a router or a router), the firewall, which is set up inside the device to construct a private network, It can not be sent out.

Consumers who purchased these systems should transmit video data and control data by opening ports of the router or router to send video data and control data from the private network to the outside, If a person is not knowledgeable about the network configuration, there is a problem that the installer must install it.

In the case of network cameras, the camera and the server device for transmitting images are integrated, making it easy for the consumer to purchase, move, and use the product. It is also sold as a wireless product have.

However, because of the difficulty of controlling the network in the way of installation, it takes a lot of time for the initial installation. If the user moves and uses the network, if the network is not knowledgeable, There are a lot.

To overcome these shortcomings, and to make installation easier and easier, a system has been devised to transmit image data or control data externally to a private network equipped with a router, a router, a firewall, and the like, without Internet connection.

The purpose of this attack is to set the network settings of the router and firewall of the installation place (port forward, virtual server setting, etc.) when transmitting image data and control data of network cameras and network equipment installed in a specific place such as a private network network And the like) without having to transmit data.

The present invention relates to a method for transmitting image data and control data of a network camera and a network device installed in a private network, the method comprising the steps of: (a) transferring equipment information from a network camera and a client server of the network equipment to a designated port of the relay server; ; (b) receiving equipment information from a relay server to a client server and transmitting reception completion information back to the client server; (c) storing client server information received in a higher level for each client server in a relay server; (d) requesting data of the network camera and network equipment of the user to the relay server through the personal computer or the portable terminal; (e) connecting a higher-level connecting client server with a port of the requesting equipment of the user, and transmitting the video data and the control data to the user's equipment.

The above method can be applied not only to a private network but also to a network which is installed in a network including all network facilities in which a security program such as a firewall using existing global IP or a firewall concealing network information is installed, Camera and network equipment can be operated in the same way.

The present invention also relates to a system for transmitting video data and control data of a network camera and network equipment installed in a private network, the system comprising: a) a network camera and a network device, A client server system having a function; b) a client server registration system for receiving the client server information in one port and sorting information of each client server into a database; c) a client server database for storing and classifying the client server information provided in the above; d) a service subscription system for registering information of service users who use the service at a remote location; e) a user database for storing and classifying said information; f) a relay server system for confirming information of the user database and the client server database when a service user at a remote location requests image data or control data to connect the service user and the client server.

According to the present invention, it is possible to eliminate the inconvenience of setting up network information at the time of installing a product in order to use image data or control data at a remote location in the case of existing network cameras and network equipment, I have implemented a system that can do that. The network configuration is not required when installing a network camera or network equipment, so mobility is guaranteed to be installed without a installer when moving to a place where the consumer needs it. Also, the installer can solve the problem (installation and management) It is possible to reduce the management cost of the company operation.

In addition, even in the security part of the system, compared with the existing system in which a port of a specific network is opened and a port of a firewall is opened for transferring data on the network by opening an arbitrary port not designated at the time of a user request, The system can be used more safely.

The present invention relates to a method for transmitting image data and control data of a network camera and a network equipment installed in a private network. More particularly, the present invention relates to a method for installing and using a network device in an Internet network that can not transmit external data, such as a global Internet network other than a private network, or a firewall in a global Internet network, without any additional setting.

1 shows a block diagram of an entire system according to an embodiment of the present invention. The user 160 installs the client server 100 together with the network camera 101 or the network equipment 102 at a place where transmission of the video data and the control data is required and connects the Internet line composed of the public IP or the private IP . Preferably, the client server 100 may be included in the network camera 101 or the network device 102 in the form of a program or a chip, or may be configured as an external hardware. In addition, the Internet may be any Internet network that can transmit data to the public IP at the end regardless of whether it is wired, wireless, CDMA, WIBRO, or the like. However, it may be excluded in the case of a VPN whose information transmission is restricted for personal purposes.

The client server 100 connected to the Internet line connects to the client server registration system 110 and transmits the MAC address, the serial number, and installed network information to the client server registration system 110.

The client server registration system 110 transmits the reception completion information to the client server 100 when the client server 100 is normally connected and the client server 100 information received by the client server registration system 110 is transmitted to the client server 100. [ And stored in the database 120.

As shown in FIG. 3, the information of the client server 100 stores the IP information of the connected location based on the serial and the MAC address information together with the transmitted port information in the client server database 120.

When the installation of the client server 100 is completed, the user 160 accesses his / her site from the portable terminal 161 such as the personal computer 162 at the remote location, the smartphone of the user, the tablet PC and the feature phone, 140, and the information of the subscribed service users is stored in the user database 150. [

4, the user database 150 stores the user's name, password, telephone number, product registration information (serial number, MAC address) and the like together with the ID stored by the user through the service subscription system 140 .

When the user requests video data of the network camera 101 of the user registered in the upper part through the personal computer 162 at the remote place or the portable terminal 161, the relay server 130 registers the user 160 The client server 100 confirms the user registration information through the user database 150 and confirms the serial number and the MAC address of the registered client server 100, And receives the port information to be used in the connection and connects to the port to which the user 160 is connected to transmit the image data held by the client server 100 to the user's personal computer 162 or the portable terminal 161.

Accordingly, the user 160 can view the video data on the user's remote personal computer 162 or the portable terminal 161 through a simple Internet connection of the client server 100 without having to set up a network.

FIG. 2 is a flowchart of a client server registration process according to the method of FIG. 1. When a user installs a client server in a specific place and connects to the Internet (200), the client server accesses the client server registration information (210). At this time, if the server is connected to the Internet line where there is no Internet signal or the internet is not normally supplied and normal information is not transmitted to the client server registration system, the system is configured such that registration is not possible when the user registers his / This is a method for preventing the user from guessing and registering the serial number or the MAC address of another person.

The client server registration system checks whether the client server is normally connected (220), and transmits a confirmation (230) to the client server to confirm that the connection is established when the normal connection is confirmed. If the client server is not normally connected to the Internet, the client server indicates that the server is not normally connected to the Internet in a hardware manner such as "drive indicator ", and the user uses the personal computer or portable device , The message "No registered server" is transmitted to the user's personal computer (240) when registering on the Internet. When the client server information is normally received in the client server registration system, the client server registration system stores (250) the client server information in the client server database, and ends the registration process.

FIG. 5 shows a user system flow diagram according to service execution. When a user requests (400) data of a client server, the relay server extracts (410) information of the client server from the client server database. Thereafter, the relay server transmits a signal for confirming the operation of the server to the client server (420). When the server operation is confirmed, the relay server receives the port information of the client server from the client server (430). The relay server 440 connects the port transmitted from the client server to the port connected to the user, and the user can receive the requested data 450 through the personal computer or the portable terminal requesting the data. If you do not check the server's operation when checking the server's operation, the user's terminal may display "Server not connected or network problem". (460) and completes the message.

Although the method described above is an example of image data transmitted from a client server, the method can transmit all data that can be digitized, such as control data and sensing signals, in addition to image data.
