[0100] In the related art, before accessing a network device through a terminal device, a network connection needs to be established between the terminal device and the video recorder. Usually, the network connection between the terminal device and the video recorder is established in the following ways: Set up a wireless local area network for the terminal device and the video recorder so that the terminal device and the video recorder are in the same wireless local area network, and establish a network connection between the terminal device and the video recorder in this wireless local area network. Or, configure a display screen for the video recorder, display the connection information of the video recorder through the display screen, and the terminal device establishes a network connection between the terminal device and the video recorder according to this connection information.

[0101] In the above process, before the terminal device accesses the video recorder, it is necessary to set up a wireless local area network or configure a display screen for the video recorder, and the operation process is complex, resulting in a relatively high complexity for the terminal device to access the video recorder.

[0102] To solve the above technical problems, an embodiment of the present application provides a video recorder and a method for accessing a video recorder. The terminal device is connected to the video recorder through a USB cable, and a network connection between the terminal device and the video recorder is created. Through the USB cable and the network connection, the video recorder sends the video recorder information of the video recorder to the terminal device. In this way, there is no need to configure a display screen for the video recorder or set up a wireless local area network for the terminal device and the video recorder. The terminal device can directly connect to the video recorder through the USB cable to create a network connection between the terminal device and the video recorder, with simple operation and reduced complexity of accessing the video recorder by the terminal device.

[0103] Next, the technical solutions shown in the present application will be described in detail through specific embodiments. It should be noted that the following several embodiments can exist independently or be combined with each other. For the same or similar content, it will not be repeated in different embodiments.

The execution subject of the embodiment of the present application can be a terminal device or a control device provided in the terminal device. The control device can be implemented by software or by a combination of software and hardware. Refer to Figure 2 , the method includes:

[0105] S201. In response to the connection of the terminal device to the video recorder through the USB cable, display a first page.

[0106] The first page can be used for the user to select the purpose of the USB connection. The first page can include a network sharing control. The network sharing control can be used to implement the network connection between the terminal device and the device connected through the USB cable.

[0107] When the terminal device detects that the terminal device is connected to the video recorder through the USB cable, in response to the connection between the terminal device and the video recorder, display the first page.

[0108] Next, in combination with Figure 3 , an explanation of the display of the first page will be given.

[0112] The triggering operation can include a click operation, a double-click operation, a swipe operation, etc., which are not limited here.

[0113] The terminal device can detect the triggering operation of the user on the network sharing control. In response to this triggering operation, start the driver program to create a network connection between the terminal device and the video recorder.

[0114] Among them, the driver program can be a Remote Network Driver Interface Specification (RNDIS) driver, which is not limited here.

[0115] Optionally, the network connection between the terminal device and the video recorder can be created in the following way: In response to the triggering operation on the network sharing control, assign a first Internet Protocol (IP) address to the terminal device; assign a second IP address to the video recorder through the virtual network card in the video recorder to achieve the creation of the network connection.

[0116] Among them, the first IP address can be an IP address automatically obtained by the terminal device.

[0117] For example, the terminal device assigns a first IP address of 192.168.4.215 to itself.

[0118] The virtual network card can be generated after the video recorder is connected to the terminal device via a USB cable. The virtual network card can simulate the function of a physical network card through the application program of the video recorder, enabling the virtual machine to be interconnected with the external network.

[0119] The second IP address can be an IP address selected by the video recorder from multiple idle IP addresses sent by the terminal device.

[0120] For example, the second IP address can be 192.168.4.256.

[0121] S203. Display the second page.

[0122] The second page may include a scanning control. The scanning control can be used to discover devices that can be interconnected. The scanning control can scan devices within the same local area network, or can also scan devices connected to the network through a USB connection cable.

[0127] Next, in conjunction with Figure 4 , an explanation will be given on how the terminal device obtains the video recorder information of the video recorder through a USB connection cable and a network connection in response to a triggering operation on the scanning control, and displays the video recorder information.

[0128] Figure 4 This is another schematic diagram of the interface of the display screen provided by the embodiment of the present application. Please refer to Figure 4 , which includes interface 401 and interface 402.

[0129] Please refer to interface 401. The second page is displayed in interface 401, and the second page includes a scanning control. The user can trigger the scanning control, and the terminal device turns on the device scanning function.

[0130] Please refer to interface 402. In interface 402, the terminal device obtains the video recorder information of the video recorder within the same local area network or connected by a USB connection cable in response to a triggering operation on the scanning control, and displays the video recorder information. The user can trigger the selection control corresponding to the video recorder to perform a connection operation on the corresponding video recorder. Among them, the information of video recorder 1, the information of video recorder 2, the information of video recorder 3, and the selection controls corresponding to each video recorder are displayed in interface 402, so that the user can select the video recorder to be connected and perform a connection.

[0131] Optionally, after the video recorder information is displayed, the information in the video recorder can be accessed and set, specifically in the following ways: Activate the video recorder through a USB cable and network connection; or, through a USB cable and network connection, obtain the camera information of at least one network camera mounted under the physical network card of the video recorder.

[0132] Among them, the activation process may include logging in user information, activating the video recorder device, etc.

[0133] The physical network card can be used for the network connection between the video recorder and the network camera, enabling the video recorder to obtain the camera information of the network camera.

[0134] For example, the cloud account of the video recorder can be logged in through a USB cable and network connection.

[0135] For another example, through the physical network card of the video recorder, the camera information of at least one network camera mounted under the physical network card can be cached in the buffer area of the video recorder, and through a USB cable and network connection, the camera information of at least one network camera can be obtained from the buffer area. Among them, the camera information may include captured picture information, video information, etc.

[0136] Among them, the process of S201 - S202 is the process of the terminal device establishing a network connection with the video recorder, and the process of S203 - S204 is the process of the terminal device scanning and connecting to the video recorder. The above two processes can be independent processes or related processes, which are not limited here.

In this way, there is no need to configure a display screen for the video recorder or build a wireless local area network for the terminal device and the video recorder. The terminal device can directly connect to the video recorder through the USB connection line to create a network connection between the terminal device and the video recorder, with simple operation and reduced complexity of accessing the video recorder by the terminal device.

[0159] Next, in combination with Figure 7 the embodiments shown, the process (S602) of requesting the terminal device to create a network connection between the video recorder and the terminal device through the USB connection line and the virtual network card will be further described in detail.

[0160] Figure 7 It is a schematic flowchart of another access method of the video recorder provided in the embodiments of the present application. On the basis of the above embodiments, reference can be made to Figure 7 , and this method will be described in detail. This method includes:

[0161] S701. The video recorder sends a broadcast message to the terminal device through the USB connection line and the virtual network card.

[0162] Broadcast messages can be used for a video recorder to obtain an IP address.

[0163] Broadcast messages can include the MAC address of the video recorder.

[0164] The MAC address can be used to determine the address of the network device location.

[0165] Optionally, the broadcast message can also include the source IP address. Among them, the source IP address is the default address when the IP is missing. For example, the source IP address is 0.0.0.0.

[0166] The video recorder can obtain the MAC address of the video recorder, generate a broadcast message including the MAC address through a USB cable and a virtual network card, and send the broadcast message to the terminal device.

[0167] For example, assume that the MAC address of the video recorder is 00:1A:2B:3C:4D:5E. The broadcast message sent by the video recorder can include the MAC address 00:1A:2B:3C:4D:5E of the video recorder and the source IP address 0.0.0.0, so that other devices in the same network segment can know that the video recorder has no valid IP address at this time and needs to assign an IP address to the video recorder.

[0168] S702. The terminal device determines multiple idle IP addresses according to the broadcast message.

[0169] The idle IP address can represent an IP address that is idle in a certain network segment.

[0170] The terminal device can obtain all IP addresses in the network segment where the terminal device is located according to the broadcast message and determine multiple idle IP addresses.

[0171] For example, multiple idle IP addresses can be represented by Table 1:

[0172] Table 1

[0173] Idle IP address Content Idle IP address 1 192.168.4.156 Idle IP address 2 192.168.4.178 Idle IP address 3 192.168.4.196

[0174] S703. The terminal device sends multiple idle IP addresses to the video recorder through a USB cable and a virtual network card.

[0175] The terminal device combines multiple idle IP addresses for processing, generates address allocation information, and sends the address allocation information to the video recorder through a USB cable and a virtual network card.

[0176] S704. The video recorder determines a second IP address among multiple idle IP addresses.

[0177] The second IP address can be the IP address determined by the video recorder for itself.

[0178] The video recorder can obtain the address allocation information sent from the terminal device, parse and process the address allocation information to obtain multiple free IP addresses, and the video recorder can determine the second IP address from the multiple free IP addresses.

[0179] For example, assume that the video recorder selects the free IP address 2 from the 3 free IP addresses in Table 1 above, that is, determines 192.168.4.178 as the IP address of the video recorder.

[0180] S705. The video recorder sends the second IP address to the terminal device through the USB cable and the virtual network card to create a network connection.

[0181] The video recorder can generate response information according to the second IP address, and send the response information to the terminal device through the USB cable and the virtual network card, so that the terminal device can determine the second IP address of the video recorder and create a network connection.

[0182] For the implementation content of each step in the embodiments of the present application, reference may be made to the description of the corresponding steps or operations in the above method embodiments, and repeated content will not be elaborated.

[0183] The access method of the video recorder provided in this embodiment is as follows: the video recorder sends a broadcast message to the terminal device through the USB cable and the virtual network card, the terminal device determines multiple free IP addresses according to the broadcast message, sends the multiple free IP addresses to the video recorder through the USB cable and the virtual network card, the video recorder determines the second IP address from the multiple free IP addresses, and sends the second IP address to the terminal device through the USB cable and the virtual network card to create a network connection. In this way, there is no need to configure a display screen for the video recorder or build a wireless local area network for the terminal device and the video recorder. The terminal device can directly connect to the video recorder through the USB cable, allocate an IP address to the video recorder, and create a network connection between the terminal device and the video recorder, which is simple to operate and reduces the complexity of the terminal device accessing the video recorder.

[0187] In response to a trigger operation on the scanning control, generate a broadcast packet for device discovery, and send the broadcast packet to all devices in the same network segment via a USB cable and a network connection.

[0188] Among them, the broadcast packet may include multiple fields.

[0189] For example, the multiple fields may include a search target field, etc., and the search target field may specify the device type to be searched.

[0190] S802. Receive the video recorder information sent by the video recorder via a USB cable and a network connection.

[0191] The video recorder information may include an IP address, a device model, a device name, etc.

[0192] After receiving the search broadcast packet sent by the terminal device, the video recorder may obtain the video recorder information, perform message processing on the video recorder information to generate device response information, and send the device response information to the terminal device via a USB cable and a network connection. The terminal device receives the device response information, parses and processes the device response information to obtain the video recorder information sent by the video recorder, and completes the process of device discovery.
