To facilitate understanding of the embodiments of this application, the application will be described in detail below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0122] To address the technical problem of how to extend the data transmission distance in existing technologies, this application provides a method for providing network signals and establishing network connections in security scenarios, which can extend the data transmission distance.

[0123] Figure 1 is a flowchart illustrating a method for providing network signals in a security scenario according to an embodiment of this application. This method can be applied to one or more electronic devices such as network cameras, smartphones, laptops, desktop computers, portable computers, and servers. Furthermore, the execution entity of this method can be hardware or software. When the execution entity is hardware, it can be one or more of the aforementioned electronic devices. For example, a single electronic device can execute this method, or multiple electronic devices can cooperate with each other to execute this method. When the execution entity is software, this method can be implemented as multiple software programs or software modules, or as a single software program or software module. No specific limitations are made here.

[0124] As shown in Figure 1, the method specifically includes:

[0125] Step 101: Detect the device connection status of the target device.

[0126] In this embodiment, the target device can be any device. As an example, the target device may include, but is not limited to, a network camera, a smartphone, a laptop, a desktop computer, a portable computer, etc.

[0127] Device connection status can refer to the connection status between the target device and other devices. As an example, the target device can be represented as: the target device is connected to other devices, the target device is disconnected from other devices, other devices are plugged into the target device, and other devices are removed from the target device.

[0128] The "other devices" mentioned above can be any device other than the target device. These other devices can belong to the same or different categories as the target device. For example, both the target device and the other devices could be network cameras.

[0129] In some cases, other devices may be devices that do not have the target plugin inserted.

[0130] The target plugin's data transmission distance exceeds a preset distance threshold. In other words, the target plugin can be a long-distance data transmission plugin, such as a long-distance image transmission plugin.

[0131] The aforementioned preset distance threshold can be a predetermined distance value. For example, the preset distance threshold can be greater than or equal to 100 meters.

[0132] A long-distance data transmission plugin is a software or hardware component used to enable data transmission over a relatively long distance. Typically, the data transmission distance of a long-distance data transmission plugin is greater than or equal to 100 meters.

[0133] A long-distance image transmission plugin is a device or module that enables image data transmission over a relatively long distance. Typically, long-distance image transmission plugins can transmit image data over a distance greater than or equal to 100 meters.

[0134] Step 102: Based on the device connection status, determine whether the target device is connected to the target plugin, wherein the data transmission distance of the target plugin is greater than a preset distance threshold.

[0135] In this embodiment, please refer to the above description for the specific meanings of the target plugin and the preset distance threshold, which will not be repeated here.

[0136] Here, multiple methods can be used to determine whether the target device is connected to the target plugin based on the device connection status.

[0137] As an example, when the device connection status indicates that the target device is disconnected from other devices, it can be determined that the target device is not connected to the target plug-in. When the device connection status indicates that the target device is connected to another device, it can be determined that the target device is connected to the target plug-in.

[0138] Step 103: When the target device is connected to the target plug-in, switch the working mode of the wireless network chip of the target device to the access point mode so that the target device provides network signals as an access point, wherein the network signals are used for data transmission.

[0139] In this embodiment, the target device may be equipped with a wireless network chip (WiFi chip). A wireless network chip is an integrated circuit chip that enables a device to connect to a wireless network, and it typically integrates multiple components such as a processor, radio frequency module, and memory.

[0140] Wireless network chips can operate in various modes, including STA (Station) mode, AP (Access Point) mode, repeater mode, monitoring mode, and bridge mode.

[0141] Typically, before the target device connects to the target plugin, the target device's wireless network chip can operate in site mode.

[0142] In some optional implementations of this embodiment, when the target device accesses the target plug-in, the working mode of the wireless network chip of the target device can be switched to access point mode in the following manner:

[0143] The first step is to send a reset signal to the target plug-in.

[0144] The reset signal is used to indicate that the target plug-in enters a preset state.

[0145] The aforementioned preset state is usually a known state. Once the target plugin enters the preset state, the initialization of the target plugin can be completed.

[0146] The second step is to send the reset signal to the target plug-in and then switch the working mode of the wireless network chip of the target device to access point mode.

[0147] It is understandable that, among the above optional implementation methods, the target plugin can be controlled to enter a preset state to achieve its initialization. This can avoid problems such as abnormal operation, lag, and data errors in the plugin, thereby improving the stability of data transmission.

[0148] In some optional implementations of this embodiment, before switching the operating mode of the wireless network chip of the target device to access point mode, the following steps may also be performed:

[0149] The first step is to determine the initial configuration information.

[0150] The first configuration information is: the network configuration information of the base station to which the wireless network chip of the target device is connected in the mode before the handover.

[0151] The "pre-switch mode" refers to the operating mode of the wireless network chip before switching to the access point mode.

[0152] As an example, the mode before switching can be site mode; in other words, the wireless network chip can operate in site mode before switching to access point mode.

[0153] Network configuration information may include, but is not limited to: wireless network account and wireless network password.

[0154] The second step is to determine the first configuration information as the second configuration information.

[0155] The second configuration information refers to the network configuration information of the base station to which the wireless network chip is connected in access point mode.

[0156] The third step is to configure the target device using the second configuration information.

[0157] It is understandable that, in the above-mentioned optional implementation methods, if the network configuration information of the base station to which the wireless network chip in the previous mode was connected can be determined, the same network configuration information can be used to configure the target device. This allows for more efficient network configuration of the target device. After configuration, the target device can generate an AP hotspot identical to the base station, allowing other devices to access this hotspot. Since the data transmission distance of the target plug-in is relatively long, the data transmission distance can be extended. Furthermore, when other devices are within the coverage area of ​​the network signal provided by the target device, they can automatically access the network without being aware of it, and the efficiency of other devices connecting to the target device can be improved.

[0158] In some optional implementations of this embodiment, before switching the operating mode of the wireless network chip of the target device to access point mode, the following steps may also be performed:

[0159] The first step is to generate third-party configuration information according to preset rules.

[0160] The third configuration information refers to the network configuration information of the base station to which the wireless network chip is connected in access point mode.

[0161] The aforementioned preset rules can be used to generate third configuration information.

[0162] As an example, the default rule could be: set the SSID (Service Set Identifier) ​​of the network provided by the target device to the prefix "eufy_" plus the SN (Serial Number) of the target device, and set the PWD (Password) to an 8-digit random password. Network configuration information may include, but is not limited to: the wireless network account and the wireless network password.

[0163] The second step is to configure the target device using the third configuration information.

[0164] In some cases, after configuring the target device using the third configuration information, the SSID and password can be further communicated to other devices via a private management frame communication protocol, enabling other devices to connect to the AP hotspot when they come into the WiFi coverage area of ​​the target.

[0165] It is understandable that, in the above-mentioned optional implementation methods, when the network configuration information of the base station to which the wireless network chip in the previous mode was connected cannot be directly obtained, the network of the target device can be automatically generated and configured according to preset rules. Thus, after configuration is completed, other devices can still access the hotspot. Therefore, even when the network configuration information of the base station to which the wireless network chip in the previous mode was connected cannot be directly obtained, other devices can still automatically access the network without being aware of it when they are within the coverage area of ​​the network signal provided by the target device, and the efficiency of other devices connecting to the target device can be improved.

[0166] In some optional implementations of this embodiment, before switching the operating mode of the wireless network chip of the target device to access point mode, the following steps may also be performed:

[0167] The first step is to obtain the first address information.

[0168] The first address information is the address information of the base station to which the wireless network chip of the target device is connected.

[0169] As an example, the first address information may include, but is not limited to: channel, IP (Internet Protocol) address, and subnet mask.

[0170] The subnet mask is a 32-bit binary number used to distinguish between the network address and the host address in an IP address. It can be used in conjunction with an IP address to determine the network range to which an IP address belongs.

[0171] An IP address is a contiguous range of IP addresses, defined and divided by a subnet mask. Devices on the same network segment can communicate directly, while devices on different network segments need to communicate through a router.

[0172] The second step is to configure the address information of the target device based on the first address information, after obtaining the first address information.

[0173] As an example, if the first address information includes an IP network segment and a subnet mask, the target device's hotspot AP can be set to an IP network segment different from the base station based on the subnet mask and IP network segment in the first address information, and then the corresponding routing rules can be configured.

[0174] Routing rules are used to determine how to forward data packets. Based on the destination IP address and information in the routing table, it can be determined from which interface the data packet should be sent out to reach the target network segment.

[0175] It is understood that, in the above optional implementation methods, the address information of the target device can be configured based on the address information of the base station to which the wireless network chip of the target device is connected. In this way, the address of the target device can be avoided from conflicting with the address of the base station.

[0176] In some optional implementations of this embodiment, before switching the operating mode of the wireless network chip of the target device to access point mode, the following steps may also be performed:

[0177] The first step is to obtain the first address information.

[0178] The first address information is the address information of the base station to which the wireless network chip of the target device is connected.

[0179] As an example, the first address information may include, but is not limited to: channel, IP (Internet Protocol) address, and subnet mask.

[0180] The subnet mask is a 32-bit binary number used to distinguish between the network address and the host address in an IP address. It is used in conjunction with the IP address to determine the network range to which an IP address belongs.

[0181] An IP address is a contiguous range of IP addresses, defined and divided by a subnet mask. Devices on the same network segment can communicate directly, while devices on different network segments need to communicate through a router.

[0182] The second step is to configure the address information of the target device to a preset address information if the first address information is not obtained.

[0183] The preset address information can be a pre-determined address. For example, the preset address information could be: IP address segment 192.168.1.1, subnet mask 255.255.0.0.

[0184] It is understood that, in the above optional implementation methods, if the first address information cannot be obtained, the address information of the target device can be configured to a preset address information, which can improve the efficiency of network configuration.

[0185] It should be noted that, where there is no conflict, the technical features described in different alternative implementations can be included in the same embodiment. For the sake of brevity, they will not be elaborated here.

[0186] The network signal provision method provided in this application can detect the device connection status of a target device, and then, based on the device connection status, determine whether the target device is connected to a target plug-in, wherein the data transmission distance of the target plug-in is greater than a preset distance threshold. Then, if the target device is connected to the target plug-in, the operating mode of the target device's wireless local area network chip is switched to access point mode, so that the target device acts as an access point to provide network signals, wherein the network signals are used for data transmission. Therefore, when the target device is connected to the target plug-in, the operating mode of the target device's wireless network chip can be automatically switched to access point mode, so that the target device acts as an access point to provide network signals. In this way, by connecting to the target plug-in, the coverage area of ​​the network signal can be expanded, thereby extending the data transmission distance.

[0187] Figure 2 is a flowchart illustrating another method for providing network signals in a security scenario according to an embodiment of this application. As shown in Figure 2, the method specifically includes:

[0188] Step 201: Detect the device connection status of the target device.

[0189] In this embodiment, step 201 is basically the same as step 101 in the embodiment corresponding to Figure 1, and will not be described again here.

[0190] Step 202: Determine whether the device connection status has changed.

[0191] In this embodiment, when the device connection state changes from one state to another, it can be determined that the device connection state has changed.

[0192] Step 203: If the device connection state changes, determine the event type of the event that triggered the change in the device connection state.

[0193] In this embodiment, the event type may include one of the following: the target device is in a state of being connected to other devices, the target device is in a state of being disconnected from other devices, other devices are inserted into the target device, and other devices are removed from the target device.

[0194] Step 204: Determine whether the event type indicates device access.

[0195] Step 205: If the event type indicates device access, obtain the description information of the access device of the target device.

[0196] In this embodiment, the access device can be another device that accesses the target device. For example, the access device can be the target plugin mentioned above, or it can be something other than the target plugin mentioned above.

[0197] The description information can be used to uniquely identify the aforementioned access devices. For example, the description information could be: Vendor ID, Product ID, etc.

[0198] Step 206: Based on the description information, determine whether the target device is connected to the target plugin, wherein the data transmission distance of the target plugin is greater than a preset distance threshold.

[0199] In this embodiment, after obtaining the description information, it can be further determined whether the target device is connected to the target plugin through the description information.

[0200] Step 207: When the target device is connected to the target plug-in, switch the working mode of the wireless network chip of the target device to access point mode so that the target device provides network signals as an access point, wherein the network signals are used for data transmission.

[0201] In this embodiment, step 207 is basically the same as step 103 in the embodiment corresponding to Figure 1, and will not be described again here.

[0202] In some optional implementations of this embodiment, when the event type indicates device access, the description information of the access device of the target device can be obtained in the following manner:

[0203] The first step is to send a target request to the access device of the target device.

[0204] The target request is used to request description information of the access device.

[0205] The second step is to receive the description information returned by the access device.

[0206] It is understandable that, among the above optional implementation methods, requesting the description information from the access device can improve the accuracy of obtaining the description information.

[0207] It should be noted that, in addition to the contents described above, this embodiment may also include the corresponding technical features described in the embodiment corresponding to FIG1, thereby achieving the technical effect of the method for providing network signals in the security scenario shown in FIG1. ​​For details, please refer to the relevant description in FIG1. ​​For the sake of brevity, it will not be elaborated here.

[0208] The method for providing network signals in a security scenario provided in this application embodiment can determine whether the target device is connected to a target plugin based on the description information of the connected device when the device connection status of the target device changes and the event type of the event that triggers the change in device connection status indicates device access. This improves the accuracy of determining whether the target device is connected to the target plugin.

[0209] Figure 3 is a flowchart illustrating a method for establishing a network connection in a security scenario according to an embodiment of this application. This method can be applied to one or more electronic devices such as network cameras, smartphones, laptops, desktop computers, portable computers, and servers. Furthermore, the execution entity of this method can be hardware or software. When the execution entity is hardware, it can be one or more of the aforementioned electronic devices. For example, a single electronic device can execute this method, or multiple electronic devices can cooperate with each other to execute this method. When the execution entity is software, this method can be implemented as multiple software programs or software modules, or as a single software program or software module. No specific limitations are imposed here.

[0210] In some cases, the entity that performs the method of establishing a network connection in a security scenario can be a network camera, and the entity that performs the method of providing network signals in a security scenario can be another network camera.

[0211] As shown in Figure 3, the method specifically includes:

[0212] Step 301: Determine the target network signal found by the networked device.

[0213] In this embodiment, the network-connected device can be any device to be connected to the network. As an example, the network-connected device may include, but is not limited to, network cameras, smartphones, laptops, desktop computers, and portable computers.

[0214] The target network signal can include all network signals detected by the connected device.

[0215] Step 302: Based on the target network signal, determine whether to establish a network connection with the target device, wherein the target device is used to provide network signals in accordance with the method for providing network signals in the security scenario.

[0216] In this embodiment, the target device can be any device. As an example, the target device may include, but is not limited to, a network camera, a smartphone, a laptop, a desktop computer, a portable computer, etc.

[0217] The aforementioned network-connected device and the aforementioned target device can be two different devices. The network-connected device and the target device can belong to the same category or different categories. For example, both the target device and the network-connected device can be network cameras.

[0218] In some cases, the networked device may be a device without the target plug-in inserted.

[0219] The target plugin's data transmission distance exceeds a preset distance threshold. In other words, the target plugin can be a long-distance data transmission plugin, such as a long-distance image transmission plugin.

[0220] The aforementioned preset distance threshold can be a predetermined distance value. For example, the preset distance threshold can be greater than or equal to 100 meters.

[0221] A long-distance data transmission plugin is a software or hardware component used to enable data transmission over a relatively long distance. Typically, the data transmission distance of a long-distance data transmission plugin is greater than or equal to 100 meters.

[0222] A long-distance image transmission plugin is a device or module that enables image data transmission over a relatively long distance. Typically, long-distance image transmission plugins can transmit image data over a distance greater than or equal to 100 meters.

[0223] In some optional implementations of this embodiment, the following method can be used to determine whether to establish a network connection with the target device based on the target network signal:

[0224] If the target network signal includes a network signal provided by the target device according to the method of providing network signals in the security scenario, and the target network signal does not include a network signal provided by the base station, then it is determined that a network connection is established with the target device.

[0225] It is understandable that in the above optional implementation methods, if the network device is far from the base station and is not within the coverage area of ​​the base station's network signal, but is within the coverage area of ​​the network signal provided by the target device, the network device can establish a network connection with the target device and thus realize data transmission, thereby increasing the data transmission distance.

[0226] In some optional implementations of this embodiment, after determining the target network signal searched by the networked device, the following steps may also be performed:

[0227] When the target network signal includes a network signal provided by the target device according to the method of providing network signals in the security scenario, and the target network signal includes a network signal provided by the base station, the network device is controlled to establish a network connection with the base station.

[0228] It is understandable that in the above optional implementation methods, when the network device is located within the coverage area of ​​the base station's network signal and also within the coverage area of ​​the network signal provided by the target device, the network device can preferentially connect to the network provided by the base station, thereby improving the stability of data transmission.

[0229] Step 303: If it is determined that a network connection has been established with the target device, control the networked device to establish a network connection with the target device and to transmit data through the established network connection.

[0230] In this embodiment, after the network connection is established between the network device and the target device, data transmission can be performed through the established network connection.

[0231] It should be noted that, where there is no conflict, the technical features described in different alternative implementations can be included in the same embodiment. For the sake of brevity, they will not be elaborated here.

[0232] The method for establishing a network connection in a security scenario provided in this application embodiment determines a target network signal searched by a networked device, and then determines whether to establish a network connection with the target device based on the target network signal. The target device provides a network signal according to the method for providing network signals in the security scenario. Then, if it is determined that a network connection will be established with the target device, the networked device is controlled to establish the network connection with the target device and to transmit data through the established network connection. Therefore, the networked device can establish network connections with target devices over a wider range, thereby extending the data transmission distance.

[0233] The following describes the embodiments of this application by way of example. However, it should be noted that the following content is only used to understand the technical solutions of the embodiments of this application and does not constitute a limitation on the protection scope of the embodiments of this application.

[0234] Before introducing this plan, the following explanations are provided for the technical terms used in it:

[0235] SSID is the name of a WiFi network.

[0236] An access point (AP) is a device that provides wireless network connectivity.

[0237] STA mode is the mode in which a WiFi device connects to an AP as a client.

[0238] AP mode is a mode in which a WiFi device acts as an access point to provide wireless network connectivity.

[0239] A channel is a frequency range used in wireless communication.

[0240] DHCP (Dynamic Host Configuration Protocol) can be used to automatically assign IP addresses.

[0241] dnsmasq: A lightweight DHCP and DNS (Domain Name System) server.

[0242] hostapd: A tool for configuring and managing AP modes.

[0243] wpa_supplicant: A tool for managing WiFi connections, typically used in STA mode.

[0244] Current IPC (IP Camera, network camera) and similar products (i.e., the aforementioned target devices) typically use wireless communication technologies such as WiFi for easy installation and use. However, WiFi has a relatively short operating range, making it difficult to meet the communication needs of scenarios requiring whole-house or whole-farm coverage.

[0245] Therefore, for these scenarios, this solution has developed accessories and other products that support long-distance image transmission (i.e., the aforementioned target plug-in, which is an auxiliary device or component that can help achieve long-distance image transmission). However, when these IPCs are used with these long-distance accessories, their original WiFi chip will be wasted if it is in STA mode.

[0246] Based on considerations of maximizing utilization and saving costs, this solution will connect to the WiFi of long-distance image transmission accessories, enable the AP (Access Point) function, and negotiate the same SSID and PWD (i.e., the second configuration information mentioned above) as the original base station. In this way, users can continue to use low-cost WiFi access to expand the monitoring area on the basis of this long-distance IPC without having to perform re-pairing or other actions, which is both cost-effective and convenient.

[0247] The WiFi chip originally operated in STA mode for IPC products. When connected to a base station hotspot within WiFi range, the IPC device could record information such as the base station's hotspot account (i.e., the first configuration information mentioned above), password (i.e., the first address information mentioned above), channel (i.e., the first address information mentioned above), IP network segment (i.e., the first address information mentioned above), and network mask (i.e., the first address information mentioned above). Then, by extending the distance between the IPC device and the base station and using a long-distance image transmission plugin, the IPC device could continue to communicate with the base station, but the WiFi chip was not working at this time.

[0248] Here, the WiFi chip can be utilized by switching its operating mode from STA mode to AP mode, allowing other devices (i.e., the aforementioned network devices) to connect to it, thereby extending the network coverage.

[0249] The following are the differences between general scenarios and distance-extended scenarios:

[0250] As shown in Figure 4A, in a typical WiFi connection scenario, the base station's Ethernet port connects to the external network, and multiple IPC devices are connected to its AP hotspot.

[0251] As shown in Figure 4B, in the distance extension scenario, both the base station and the IPC device are connected to the long-distance image transmission plugin. The IPC device can also switch the working mode of the WiFi chip to AP mode, allowing other IPC devices (i.e., the aforementioned network devices) to connect, thus playing a role in distance extension.

[0252] The automatic mode switching process is shown in Figure 4C. When the IPC device (i.e. the target device mentioned above) is connected to the long-distance image transmission plug-in through the USB (Universal Serial Bus) interface, the USB controller in the IPC device can detect the change in physical connection (i.e., whether the device connection status has changed) and generate a hardware interrupt signal.

[0253] After receiving the signal, the kernel of the IPC device calls the corresponding interrupt handler. The interrupt handler reads the status register of the USB controller to confirm the specific event type (such as device insertion, device removal, etc.).

[0254] The device enumeration process begins, its purpose being to identify and initialize newly connected USB devices (i.e., the access devices mentioned above) so that the host can communicate with them. The enumeration process involves sending a series of standard USB requests to obtain device descriptor information (such as Vendor ID, Product ID, etc.) and assigning an address to the USB device.

[0255] Specifically, the enumeration process includes:

[0256] a. Obtaining the USB Device Descriptor: The IPC device sends a GET_DESCRIPTOR request (i.e., the target request mentioned above) to the long-distance image transmission plugin to obtain the device descriptor (i.e., the description information mentioned above). The device descriptor contains basic information about the device, such as Vendor ID, Product ID, and device class.

[0257] b. Reset device: The IPC device sends a reset signal to the long-distance image transmission plug-in to ensure that the plug-in is in a known state.

[0258] c. Address allocation: The IPC device sends a SET_ADDRESS request to the long-distance image transmission plugin to allocate a unique address for the long-distance image transmission plugin.

[0259] d. Configuration settings: The IPC device sends a SET_CONFIGURATION request to the long-distance image transmission plugin to set the configuration information and put the plugin into working state.

[0260] The IPC device listens for kernel events and determines whether it is a long-distance image transmission plugin access based on the device descriptor information (Vendor ID, Product ID). If so, it triggers the WiFi chip to switch its working mode from STA mode to AP mode.

[0261] During network configuration, unified configuration can be performed without the user's awareness, and connection information does not need to be reconfigured.

[0262] When an IPC device connects to a base station hotspot using a WiFi chip in STA mode, the IPC device can record information such as the base station's hotspot account, password, channel, IP network segment, and subnet mask into flash memory for storage.

[0263] AP Hotspot Information Synchronization: When the IPC-A device (i.e. the target device mentioned above) is connected to the long-distance image transmission plugin, the WiFi chip of the IPC-A device can switch to AP mode, at which point it will determine whether base station information has been recorded.

[0264] If the flash memory contains information about the previously connected base station, the relevant information will be extracted and configured. Once the configuration is complete, IPC-A will also have an AP hotspot that is identical to the base station, allowing other IPCs (i.e., the aforementioned network devices, such as IPC-B) to access and extend the distance.

[0265] When IPC-B was originally connected to a base station, or when a user purchases it and first pairs and binds it to a base station before taking it near IPC-A for use, IPC-B can automatically access the hotspot function provided by IPC-A, allowing users to easily complete the installation and deployment.

[0266] If there is no relevant base station information in the flash, the SSID of the IPC-A device AP is set to the prefix "eufy_" plus the device SN number, and the password PWD is set to an 8-digit random password. Then, the SSID and password are communicated to other IPC devices (such as IPC-B) through the private management frame communication protocol, so that other IPC-B devices can connect to the AP hotspot when they come into the WiFi coverage area of ​​the IPC-A. See Figures 4D and 4E.

[0267] AP interface enabled:

[0268] Stop the current WiFi connection (by default, long-distance image transmission chips are preferred for communication). Then, write the synchronized AP hotspot information to the hostapd.conf configuration file, start the hostapd and dnsmasq processes, and launch the AP hotspot's network interface. If the base station's IP address segment and subnet mask information are available, configure the IPC device's hotspot AP to a different IP address segment than the base station, and then configure the corresponding routing rules. If the base station's IP address segment and subnet mask information are not available, the default configuration is 192.168.1.1 with a subnet mask of 255.255.0.0.

[0269] It should be noted that, in addition to the contents described above, this embodiment may also include the technical features described in the above embodiments, thereby achieving the technical effects of the method shown above. Please refer to the above description for details. For the sake of brevity, it will not be elaborated here.

[0270] This solution can detect changes in the physical connection of the USB interface and automatically switch the WiFi chip's operating mode from STA mode to AP mode. This automated mode switching reduces manual operation by the user and improves the device's intelligence and ease of use. In STA mode, the IPC device records the base station's hotspot information (such as SSID, password, channel, IP network segment, subnet mask, etc.) and automatically configures this information after switching to AP mode. This unified configuration method eliminates the need for users to reconfigure connection information, improving the user experience. By connecting a long-distance image transmission plugin, the device can continue to communicate with the base station even when far away and extend network coverage using the WiFi chip's AP mode. This effectively solves the problem of limited coverage in traditional WiFi and meets communication needs in large-scale scenarios. When other IPC devices enter the WiFi coverage area of ​​an AP-mode IPC device, they can automatically connect to that AP hotspot, achieving seamless network coverage extension. This automatic connection mechanism improves system intelligence and user convenience. Therefore, through automatic mode switching and automatic connection mechanisms, the system's intelligence level is improved. Unified configuration and automatic connection reduce manual operation by the user and enhance the user experience. By combining a long-distance image transmission plugin with AP mode, the problem of limited coverage of traditional WiFi is solved, meeting the communication needs in a wide range of scenarios.
