[0051] Through the above-mentioned accompanying drawings, the clear embodiments of this application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of this application in any way, but to illustrate the concept of this application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the scope of protection of this application.

[0053] It should be noted that although the terms "first", "second", etc. are used in the embodiments of the present application to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. Optionally, without departing from the scope of the present application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

[0054] It should be understood that the terms "comprising" and "including" indicate the presence of the previously mentioned features, steps, operations, but do not exclude the presence, appearance or addition of one or at least one other feature, step, operation. The term "and / or" used in the present application can be interpreted inclusively, or means any one or any combination. Optionally, "A and / or B" means "any one of the following: A; B; A and B". Additionally, the character " / " in this text generally indicates an "or" relationship between the associated objects before and after.

[0055] In a certain network environment, a gateway device and multiple routers can be configured. Various devices can access the network by connecting to different routers. Various devices can include network cameras and network video recorders, etc.

[0056] Next, in combination with Figure 1 , an example of a certain network environment will be given.

[0057] Figure 1 FIG. is a schematic diagram of an application scenario provided by an embodiment of the present application. Please refer to Figure 1 , Figure 1 It may include a home network 100, and the home network 100 may include a gateway device 101, multiple routers 102, a network camera 103, and a network video recorder 104.

[0058] The gateway device 101 can be used to access the external network provided by the operator.

[0059] For example, the gateway device 101 can be an optical modem, and the external optical fiber can be connected to the optical modem at the user's home. The optical modem converts the received optical signal into an electrical signal that can be recognized and further processed by the router, realizing the conversion processing of network access.

[0060] The gateway device 101 can also be used to connect multiple routers 102 to achieve network coverage.

[0061] The router 102 can be used to provide a wireless network signal to devices within the wireless network signal coverage range. The devices can include a network camera 103 and a network video recorder 104.

[0062] The network camera 103 can be a video surveillance device used in a network environment to achieve functions such as security monitoring, remote viewing, and management.

[0063] The network video recorder 104 can be used to receive the video streams transmitted by at least one connected network camera 103 and centrally store these video data.

[0064] In a network configured with multiple routers, if a network camera mounted under a certain router wants to connect to a network video recorder in this network, there may be a situation where the router where the network video recorder is located is different from the router where the network camera is located.

[0065] For example, in this home network 100, the network camera 103 and the network video recorder 104 can be respectively mounted under different routers.

[0066] In the related art, to solve the connection problem between devices under different routers, it can be achieved by adding a relay device in the network or manually configuring the device connection by the user, etc.

[0067] In the above process, it is necessary to add additional devices or manually configure the device connection by the user, resulting in a low device access efficiency.

[0068] To solve the above technical problems, the embodiment of the present application provides a device access method. The first local area network addresses of multiple network devices are detected by a network camera, and the network devices are routing devices or gateway devices. For any one of the detected network devices, according to the first local area network address corresponding to the network device, the address range corresponding to the network device is determined, and the local area network addresses of the devices mounted under the network device are within this address range. According to the address ranges of each network device, the target local area network addresses of at least one network video recorder are determined, and according to at least one target local area network address, the target network video recorder in at least one network video recorder is accessed. In this way, whether the network video recorder and the network camera are mounted under the same router or not, the network camera can quickly determine the target local area network address of the network video recorder through the address ranges respectively corresponding to the multiple detected network devices and access the network video recorder, improving the device access efficiency.

[0069] Next, the technical solution 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, and the same or similar content will not be repeated in different embodiments.

[0070] Figure 2 It is a schematic flow chart of a device access method provided by the embodiment of the present application. The execution subject of the embodiment of the present application can be a network camera. See Figure 2 , and this method includes:

[0071] S201. Detect the first local area network addresses of multiple network devices.

[0072] Multiple network devices and network cameras are in the same local area network.

[0073] The network device is a routing device or a gateway device.

[0074] The first local area network address is the address corresponding to the network device within the local area network. The first local area network address can be used to identify the network device.

[0075] The network camera can detect the first local area network addresses of multiple network devices through the Internet Control Message Protocol (ICMP) protocol, or can also detect through other protocols, which is not limited here.

[0076] Optionally, an address list in the storage space can be obtained, and according to the multiple local area network addresses in the address list, address determination requests are sent respectively, response information corresponding to the multiple address determination requests is obtained, and according to the multiple response information, the first local area network addresses of the multiple network devices are determined.

[0077] Among them, the address list may include multiple local area network addresses detected during a historical period. The address determination request can be used to determine whether the address is the address corresponding to the network device within the local area network. The response information can be used to determine that the address is the address corresponding to the network device within the local area network.

[0078] Optionally, multiple probe messages can be sent through the ICMP protocol, and according to the response messages corresponding to the multiple probe messages respectively, the first local area network addresses of multiple network devices are detected.

[0079] It should be noted that the first local area network addresses of multiple network devices can be detected according to any feasible implementation manner, and the embodiments of the present application do not limit this.

[0080] Optionally, the first local area network addresses of multiple network devices can be detected in the following manner: determine multiple Time-To-Live (TTL) values of the message; in the order of the multiple TTL values from small to large, according to the multiple TTL values, perform multiple message probe processes until the first local area network addresses of multiple network devices are detected.

[0081] Among them, the multiple TTL values can sequentially increase by a preset value in the order from small to large.

[0082] The preset value can be 1.

[0083] The Time-To-Live (TTL) can be used to indicate the effective duration during which the probe message can exist and be forwarded.

[0084] When a detection message is transmitted in the network, each time it passes through a network device, the value of the TTL is decremented by 1. When the value of the TTL is decremented to 0, the network device where the detection message is located can discard the detection message and send a response message to the network camera. The response message includes the first LAN address of the network device where the detection message is located.

[0085] S202. For any network device, obtain the subnet mask corresponding to the network device, and determine the address range corresponding to the network device according to the first LAN address and the subnet mask of the network device.

[0086] The subnet mask can be used to divide the network part and the host part of the first LAN address to determine the subnet range to which the device belongs.

[0087] The LAN addresses of the devices mounted under the network device are within the address range.

[0088] The start address and the end address of the address range can be determined according to the first LAN address and the subnet mask.

[0089] Next, among the multiple network devices detected, take any one network device as an example:

[0090] The subnet mask corresponding to the network device can be obtained through the configuration information. According to the first LAN address and the subnet mask of the network device, calculate the network address and the broadcast address. Determine the address immediately following the network address as the start address, and determine the address immediately preceding the broadcast address as the end address. Determine the address range corresponding to the network device according to the start address and the end address.

[0091] Among them, the network address can be used to identify the range of the subnet.

[0092] The network address and the broadcast address can be calculated according to the first LAN address and the subnet mask of the network device in the following way: Perform binary conversion processing on the first LAN address and the subnet mask to obtain the first value corresponding to the first LAN address and the second value corresponding to the subnet mask. Perform logical AND operation processing on the first value and the second value to obtain the third value. Perform decimal conversion processing on the third value to obtain the network address. Determine the host bits according to the second value of the subnet mask. Set all the host bits in the third value to 1 to obtain the fourth value. Perform decimal conversion processing on the fourth value to obtain the broadcast address.

[0093] For example, assume that the first LAN address is 192.168.1.100 and the subnet mask is 255.255.255.0. Perform binary conversion processing on the first LAN address and the subnet mask to obtain the first value: 11000000.10101000.00000001.01100100, and the second value: 11111111.11111111.11111111.00000000. Perform logical AND operation processing on the first value and the second value to obtain the third value: 11000000.10101000.00000001.00000000. Perform decimal conversion processing on the third value to obtain the network address: 192.168.1.0. According to the second value of the subnet mask, determine that the host bits are the last eight bits. Set all the host bits in the third value to 1 to obtain the fourth value: 11000000.10101000.00000001.11111111. Perform decimal conversion processing on the fourth value to obtain the broadcast address 192.168.1.255. Determine the next address adjacent to the network address 192.168.1.0 as the starting address: 192.168.1.1, and determine the previous address adjacent to the broadcast address 192.168.1.255 as the ending address: 192.168.1.254. According to the starting address 192.168.1.1 and the ending address 192.168.1.254, determine the address range corresponding to the network device: 192.168.1.1 - 192.168.1.254.

[0094] S203. Perform device detection processing according to the address range corresponding to each network device, detect at least one network video recorder, and determine the target LAN address corresponding to each network video recorder.

[0095] The network video recorder is mounted under multiple network devices.

[0096] The target LAN address is the address corresponding to the network video recorder within the LAN.

[0097] The device detection processing can be used to detect the device information of the device.

[0098] The device detection processing can be performed according to the address range corresponding to each network device in the following two ways to detect at least one network video recorder and determine the target LAN address corresponding to each network video recorder:

[0099] Method 1: Multiple second LAN addresses can be determined according to the address range corresponding to each network device, and device detection processing is performed on the multiple second LAN addresses to obtain at least one network video recorder and determine the target LAN address corresponding to each network video recorder.

[0100] Method 2: For any network device, at least one device detection process can be performed within the address range corresponding to the network device until a network video recorder is detected, and the target LAN address corresponding to the network video recorder is determined.

[0101] Among them, the device detection process can send a data acquisition request to the device corresponding to the address within the address range through a preset protocol, and receive the data acquisition response corresponding to the data acquisition request. The data acquisition response includes the device information of the device.

[0102] The preset protocol can be a preset private protocol. The preset protocol can be the Over-The-Air Provisioning (OTAP) protocol.

[0103] Both the network camera and the network video recorder support the preset protocol.

[0104] The data acquisition request can be used to request the device information of the device.

[0105] The device information can include information such as the serial number, device identifier, device type, and device name.

[0106] If the device corresponding to the address within the address range does not support the preset protocol, the device will not send a data acquisition response when receiving the data acquisition request. If the device corresponding to the address within the address range is a network video recorder or other device that supports the preset protocol, the device can send a data acquisition response according to the data acquisition request.

[0107] Optionally, the above different methods can be determined through the user's selection operation on the detection method selection control.

[0108] It should be noted that, according to any feasible implementation method, device detection processing can be performed according to the address ranges corresponding to each network device, at least one network video recorder is detected, and the target LAN addresses corresponding to at least one network video recorder are determined. The embodiments of the present application do not limit this.

[0109] S204. Access the target network video recorder among at least one network video recorder according to at least one target LAN address.

[0110] The target LAN address can be the LAN address corresponding to the network video recorder.

[0111] There can be at least one network video recorder in the local area network.

[0112] At least one network video recorder includes the target network video recorder.

[0113] An access request can be sent to at least one network video recorder according to at least one target local area network address, an access success response sent by the target network video recorder is received, and the target video recorder is accessed according to the access success response.

[0114] Among them, the network camera can send an access request to at least one network video recorder. Only the target network video recorder among the at least one network video recorder can access the network camera according to the access request, generate an access success response, and send the access success response to the network camera.

[0115] It should be noted that the target network video recorder in at least one network video recorder can be accessed according to at least one target local area network address, and the embodiments of the present application do not limit this.

[0116] The device access method provided in this embodiment obtains the first local area network addresses of multiple network devices through detection. The multiple network devices and the network camera are in the same local area network. The network devices are routing devices or gateway devices, and the first local area network address is the address corresponding to the network device within the local area network. For any network device, the subnet mask corresponding to the network device is obtained, and according to the first local area network address and the subnet mask of the network device, the address range corresponding to the network device is determined. The local area network addresses of the devices mounted under the network device are within the address range. Device detection processing is performed according to the address ranges corresponding to the respective network devices, at least one network video recorder is detected, and the target local area network addresses respectively corresponding to the at least one network video recorder are determined. The network video recorders are mounted under multiple network devices. The target network video recorder in at least one network video recorder is accessed according to at least one target local area network address. In this way, regardless of whether the network video recorder and the network camera are mounted under the same router, the network camera can quickly determine the target local area network address of the network video recorder through the address ranges respectively corresponding to the multiple network devices detected, and access the network video recorder, improving the device access efficiency.

[0117] Next, in combination with Figure 3 , the process (S201) of detecting the first local area network addresses of multiple network devices will be explained.

[0118] Figure 3 It is a schematic flowchart of another device access method provided by an embodiment of the present application. On the basis of the above embodiment, refer to Figure 3 , and this method will be described in detail. This method includes:

[0119] S301. Determine multiple time-to-live (TTL) values of the message.

[0120] Configuration information can be obtained, and according to the configuration information, multiple time-to-live (TTL) values of the message are determined.

[0121] The configuration information may include protocol formats, multiple message survival durations, etc., which are not limited herein.

[0122] Each message survival duration increases by a preset value in sequence.

[0123] The preset value may be 1, which is not limited herein.

[0124] For example, assume that the multiple message generation durations can be 2. The first TTL can be 1 and the second TTL can be 2.

[0125] Another example, assume that the multiple message generation durations can be 3. The first TTL can be 1, the second TTL can be 2, and the third TTL can be 3.

[0126] Optionally, the configuration information may include an initial survival duration, an interval value, and a generation count. Multiple survival durations can be determined based on the initial survival duration, the interval value, and the generation count.

[0127] S302. Initialize i to 1.

[0128] S303. Generate the i-th probe message according to the i-th TTL.

[0129] The TTL of the probe message is the i-th TTL.

[0130] The i-th probe message can be generated through the Internet Control Message Protocol according to the i-th TTL.

[0131] The format of the i-th probe message can be a preset format. The i-th probe message may include a header field and a data part. The header field may include a field representing the survival duration, and the data part may include the IP address corresponding to the network camera.

[0132] S304. Receive the i-th response message corresponding to the i-th probe message. The i-th response message includes the first LAN address of the i-th network device detected.

[0133] The i-th network device can be a router or a gateway device.

[0134] For example, assume that the network camera sends the first probe message. According to the first TTL, it is determined that the TTL corresponding to the first probe message is 1. The first network device receives the first probe message, the TTL is decremented by 1, and it is determined that the TTL is 0. The first network device sends the first response message to the network camera. The first response message includes the first LAN address of the first network device.

[0135] For another example, assume that the network camera sends the second probe message. According to the second TTL, it is determined that the TTL corresponding to the second probe message is 2. The first network device receives the second probe message, decrements the TTL by 1, and determines that the TTL is 1. The first network device forwards it to the second network device. The second network device receives the second probe message, decrements the TTL by 1, and determines that the TTL is 0. The second network device sends the second response message to the network camera, and the second response message includes the first LAN address of the second network device.

[0136] For another example, assume that the network camera sends the third probe message. According to the third TTL, it is determined that the TTL corresponding to the third probe message is 3. The first network device receives the third probe message, decrements the TTL by 1, and determines that the TTL is 2. The first network device forwards the third probe message to the second network device. The second network device receives the third probe message, decrements the TTL by 1, and determines that the TTL is 1. The second network device forwards the third probe message to the third network device, decrements the TTL by 1, and determines that the TTL is 0. The third network device sends the third response message to the network camera, and the third response message includes the first LAN address of the third network device.

[0137] S305. Determine whether the first LAN address of the i-th network device is the LAN address of the gateway device.

[0138] If so, execute S306;
