The network controller may determine whether the wireless Ethernet network is active when the wired Ethernet network is in an inactive state, and compare the RSSI values of the wireless module and the mobile communication module, The transmission data may be transmitted through the transmission channel.

In addition, if the video information includes event information corresponding to motion detection, the network control unit may transmit the transmission data through the mobile communication module.

The wired module and the wireless module use a fixed IP, and the mobile communication module uses a dynamic IP.

Here, in the case of the mobile communication module, after requesting the allocation of the dynamic IP to the base station, transmission data including the dynamic IP allocated from the base station may be transmitted to the mobile terminal.

Also, the wired Ethernet network includes a LAN network, the wireless Ethernet network includes a Wi-Fi communication network, and the mobile communication network may include at least one communication network of WCDMA, CDMA, LTE, 3G, and 4G.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

1 is a communication conceptual diagram of an IP camera control apparatus according to an embodiment of the present invention. The IP camera control apparatus 100 according to the embodiment of the present invention includes not only an IP camera module but also a wired module, a wireless module, and a mobile communication module. The wired module and the wireless module may be connected to the wired / wireless router 10 to form a wired Ethernet network and a wireless Ethernet network, respectively. Also, the mobile communication module may be connected to the mobile communication base station 20 to form a mobile communication network.

The IP camera control apparatus 100 can select a transmission path suitable for the current network communication environment among the wired Ethernet network, the wireless Ethernet network, or the mobile communication network using the respective modules, and transmit the selected transmission path to the mobile terminal. Here, the mobile terminal includes a client PC 30, a smartphone 40, and the like. And the smartphone 40 is connected to the base station 50.

A Dynamic Domain Name System (DDNS) server 60 can assign an IP to a network-connected IP camera. The IP camera transmits the allocated IP information to the predetermined mobile terminal (user terminal) together with the image information in the form of a message (ex. MMS SMS). The mobile terminal can inquire the corresponding image information anytime and anywhere through this message. That is, the present embodiment allows the IP to be directly connected to the DDNS server through the URL so that the user can access the IP camera anytime and anywhere.

Fig. 2 is a configuration diagram of the IP camera control apparatus of Fig. 1, and Fig. 3 is a flowchart of an IP camera control method using Fig. The IP camera control apparatus 100 according to the present embodiment includes an imaging module 110, a wired module 120, a wireless module 130, a mobile communication module 140, and a network controller 150.

The imaging module 110 is a part for acquiring image information through a camera. The wired module 120, the wired module 120, and the mobile communication module 140 can be connected to a wired Ethernet network, a wireless Ethernet network, and a mobile communication network, respectively. The mobile communication module 140 corresponds to a mobile communication device. Here, the wired Ethernet network includes a LAN network, the wireless Ethernet network includes a Wi-Fi communication network, and the mobile communication network includes at least one communication network of WCDMA, CDMA, LTE, 3G, and 4G.

The control method is as follows. First, the imaging module 110 acquires image information for an IP camera (S310). The network controller 150 selects one of the wired module 120, the wireless module 130, and the mobile communication module 140 according to the current communication environment at step S320. Then, the network controller 150 transmits the transmission data including the image information and the IP information to the predetermined mobile terminal through the selected transmission module (S330).

That is, the network controller 150 selects a transmission path suitable for the current network communication environment and transmits the image data to the mobile terminal. A concrete embodiment of the transmission path selection method in the network control unit 150 will be described in detail below.

4 is a flowchart showing a first embodiment of a network control method according to an embodiment of the present invention.

First, the network controller 150 sets up the wired Ethernet through the wired module 120 (S410). Then, it is determined whether the wired Ethernet network (ex, LAN network) is active (S420). If the wired Ethernet network is active, the WLAN module 120 transmits the transmission data.

Alternatively, if the wired Ethernet network is in an inactive state, the mobile station transmits the transmission data through the wireless module 130 or the mobile communication module 140. That is, if the wired Ethernet network (ex. LAN network) is in the inactive state, the wireless Ethernet module 130 is set up through the wireless module 130 (S430), and it is determined whether the wireless Ethernet network (S440).

If the wireless Ethernet network is active, the wireless module 130 transmits the transmission data. Alternatively, if the wireless Ethernet network is in an inactive state, the mobile communication network 140 is set up through the mobile communication module 140 in step S450, and it is determined whether the mobile communication network ex 4G is activated in step S460.

If the mobile communication network is activated, the mobile communication module 140 transmits the transmission data. Here, if the mobile communication network is in the inactive state, step S410 is performed again. In the first embodiment as described above, the transmission path corresponding to the current network communication environment is selected and the image data can be transmitted through the transmission path.

5 is a flowchart showing a second embodiment of a network control method according to an embodiment of the present invention. First, the network controller 150 determines whether the wired Ethernet network is active (S510). If the wired Ethernet network is active, the wired Ethernet network is checked with a network priority (S550). Accordingly, transmission data can be transmitted through the wired module 120.

However, if the wired Ethernet network is in an inactive state, it is determined whether the wireless Ethernet network is active (S520). Then, the RSSI value of the wireless module 130 is measured and the RSSI value of the mobile communication module is measured (S530 to S540). Then, the RSSI values of the two modules 130 and 140 are compared with each other, and the network priority is checked (S550). Here, transmission data is transmitted through a module having a large RSSI value among the two modules 130 and 140. According to the second embodiment, it is possible to directly transmit image data to a mobile terminal through a transmission path having an excellent signal quality among transmission paths corresponding to a current network communication environment. That is, by periodically measuring the quality of the network among the services, it is possible to grasp the optimal network and operate so that there is no problem in the service.

In addition, when the image information to be transmitted includes event information corresponding to motion detection (ex, fire, intrusion), the network controller 150 transmits transmission data only through the mobile communication module 140 among the three modules . The embodiment is as follows. First, if the motion is detected, the motion detection image corresponding to the motion is stored, and it is determined whether the mobile communication network is activated. If the mobile communication network is in the inactive state, the mobile communication is set up again and the process of confirming the activation is repeated. When the mobile communication network is in the activated state, the mobile terminal transmits the motion detection event occurrence alarm, the motion detection image, and the corresponding IP information to the mobile terminal in the form of a message or the like so that it can be confirmed immediately.

Meanwhile, in the present embodiment, the wired module 120 and the wireless module 130 use a fixed IP. Assignment of static IP is done through a router like the well-known method.

Alternatively, the mobile communication module 140 uses a floating IP. The method of receiving dynamic IP allocation is as follows. First, the network controller 150 requests allocation of the dynamic IP to the mobile communication base station, then drops the existing public IP and sets the dynamic IP allocated from the mobile communication base station as the IP information. Thereafter, transmission data including the allocated dynamic IP is transmitted to the mobile terminal in the form of a message. If information about 10 user terminals is specified in the IP camera, the corresponding message will be transmitted to all 10 user terminals.

As described above, according to the present invention, a wired / wireless communication module and a mobile communication module are built in an IP camera to select an optimal transmission path suitable for a current network communication environment from a wired Ethernet network, a wireless Ethernet network, or a mobile communication network, There is an advantage that it can be transmitted directly.

That is, the present invention provides a voice and video service of an IP camera using a data service of a mobile communication device even in an environment where a wired / wireless infrastructure is not provided, supports wired / wireless networks and mobile communication networks, Can be provided. In addition, the network service can be provided by automatically determining a serviceable network through quality measurement of an existing wired / wireless network and an additional mobile communication network.

In addition, the present invention can transmit an image of an event generated to a designated user to a smart phone using mobile communication without going through a server at the time of an event, and provide an environment in which a smart phone can access the IP camera immediately . As described above, since the present invention does not require a separate server, it is simple in structure, easy to maintain and can be supplied at a lower price, and can be easily installed and used by ordinary users without network knowledge. In addition, since the mobile communication device is integrally formed with the IP camera, the production cost is reduced, which can contribute to the expansion of the line of the mobile communication service provider.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
