[0060] By adopting the above scheme, the network camera determines the configuration information of the second hotspot based on the first shared key and the device information of the network camera, and sends the related information of the configuration information of the second hotspot to the screen end. In this way, the screen end connects with the network camera based on the configuration information of the second hotspot generated based on the first shared key, and the first shared key is only known by the screen end and the network camera, so that the security of networking of the network camera and the screen end is improved.

[0061] In some possible implementation manners, on the network camera side, the method further includes: obtaining device information of the screen end through content displayed by the screen end; determining configuration information of a first hotspot based on the device information of the screen end; and generating the first hotspot of the network camera based on the configuration information of the first hotspot.

[0062] The obtaining of the device information of the screen end through the content displayed by the screen end can include: the network camera obtaining the device information of the screen end by scanning a two-dimensional code displayed on a display screen of the screen end, wherein the device information of the screen end can include a MAC (Media Access Control Address, physical address) of the screen end and first preset first hotspot template information.

[0063] The determining the configuration information of the first hotspot based on the device information of the screen terminal can include: generating a name of the first hotspot based on at least part of characters in the MAC of the screen terminal, the first preset first hotspot template information, and predefined information in the network camera; and determining the configuration information of the first hotspot of the network camera based on the name of the first hotspot, a preset first hotspot password in the network camera, and an attribute of the first hotspot, wherein the attribute of the first hotspot is used to indicate that the first hotspot is in a hidden state or a broadcast state. For example, the configuration information of the first hotspot can include: the name of the first hotspot camera-060a02_ap633A, wherein camera and ap are predefined information, 060a02 is the first preset first hotspot template information, and 633A is the last four characters of the MAC of the screen terminal; the preset first hotspot password is empty, and the attribute of the first hotspot is in the hidden state. This is only an example, and the preset first hotspot password can be set according to actual conditions, for example, the preset first hotspot password can be any other character or string, the attribute of the first hotspot can be in the hidden state or the broadcast state, and the predefined information in the network camera can be set according to actual conditions, which is not limited here.

[0064] In some possible implementation manners, on the network camera side, before the network camera is connected with the screen terminal as the first hotspot, the method further includes: determining the configuration information of the first hotspot based on device information of the network camera, wherein the device information of the network camera can include a MAC (Media Access Control Address, physical address) of the network camera and second preset first hotspot template information.

[0065] The determining the configuration information of the first hotspot based on the device information of the network camera includes: generating a name of the first hotspot based on at least part of characters in the MAC of the network camera, the second preset first hotspot template information in the network camera, and predefined information in the network camera; and determining the configuration information of the first hotspot of the network camera based on the name of the first hotspot, a preset first hotspot password in the network camera, and an attribute of the first hotspot, wherein the attribute of the first hotspot is used to indicate that the first hotspot is in a hidden state or a broadcast state. The generation manner of the name of the first hotspot is the same as the above manner, which is not described herein again.

[0066] In some possible implementation manners, on the screen terminal side, the method further includes: in a case where the screen terminal is in an unbound state, displaying device information of the screen terminal on the screen terminal, wherein the device information of the screen terminal is used by the network camera to determine the configuration information of the first hotspot; and connecting with the network camera based on the configuration information of the first hotspot.

[0067] The manner of determining the screen end binding state can be: in a case where a factory mode (factory mode) in a factory (Factory) partition of the screen end is a first value, determining that the state of the screen end is an unbound state; in a case where the factory mode in the factory (Factory) partition of the screen end is a second value, determining that the state of the screen end is a bound state, wherein the factory partition can be a partition for storing a factory program or firmware of the screen end. For example: in a case where factory_mode in the factory partition is 0, the state of the screen end is an unbound state; in a case where factory_mode in the factory partition is 1, the state of the screen end is a bound state, which is only an example for illustration, and the specific setting manner is set according to actual conditions.

[0068] The screen end can display device information of the screen end, which can include: generating a two-dimensional code based on a MAC of the screen end and first preset first hotspot template information in the screen end; and displaying the two-dimensional code on a display screen of the screen end.

[0071] Optionally, in a case where the screen end is in an unbound state, the screen end can detect first hotspot signals of one or more network cameras; in the detection of the first hotspot signals of the one or more network cameras, the screen end can select a first hotspot signal with the strongest signal, and connect with the first hotspot with the strongest signal based on a preset first hotspot password in the screen end.

[0072] Optionally, in the case that the screen end is in the binding state, the screen end detects a first hot spot signal of the one or more network cameras, in the screen end detecting the first hot spot signal of the one or more network cameras, a first hot spot of any one of the network cameras is selected, and the first hot spot of any one of the network cameras is connected based on a preset first hot spot password in the screen end.

[0073] By using the above scheme, the network camera can generate the configuration information of the first hot spot of the network camera by acquiring the device information of the screen end, and the screen end can connect the network camera based on the configuration information of the first hot spot. In this way, the network camera and the screen end can generate the same configuration information of the first hot spot, and then automatically connect through the same configuration information of the first hot spot, which can improve the efficiency of network camera and screen end networking.

[0074] In some possible implementation manners, the network camera side negotiates with the screen end to obtain a first shared key, including: receiving a first public key sent by the screen end; generating a second public key and a second private key of the network camera; generating the first shared key based on the first public key and the second private key; and sending the second public key to the screen end, where the second public key is used by the screen end to generate the first shared key.

[0075] The generating of the second public key and the second private key of the network camera can be generating the second public key and the second private key of the network camera based on a key agreement algorithm, where the key agreement algorithm includes one of the following: an ECDH (Elliptic Curve Diffie-Hellman key Exchange) algorithm and a DH (Diffie-Hellman) algorithm. Other algorithms can also be used as long as they can achieve the algorithm of the present embodiment.

[0076] The generating of the first shared key based on the first public key and the second private key can include: generating the first shared key based on the first public key and the second private key by using a key agreement algorithm.

[0077] In some possible implementation manners, the screen end side negotiates with the network camera to obtain a first shared key, including: generating a first public key and a first private key of the screen end; sending the first public key to the network camera, where the first public key is used by the network camera to generate the first shared key; receiving a second public key sent by the network camera; and generating the first shared key based on the first private key and the second public key.

[0079] The generating the first shared key based on the first private key and the second public key can include generating the first shared key based on the first private key and the second public key by using a key agreement algorithm.

[0080] By using the above scheme, the network camera and the screen terminal negotiate the first shared key. In this way, the network camera and the screen terminal have the same first shared key, and the configuration information of the second hotspot generated by the first shared key is known only to the screen terminal and the network camera, so that the security of the network camera and the screen terminal is improved.

[0081] In some possible implementation manners, the network camera side, the determining the configuration information of the second hotspot based on the first shared key and the device information of the network camera can include: determining the name of the second hotspot based on the device information of the network camera; determining the password of the second hotspot based on the first shared key; and taking the name of the second hotspot and the password of the second hotspot as the configuration information of the second hotspot.

[0082] The determining the name of the second hotspot based on the device information of the network camera can include generating the name of the second hotspot based on at least part of characters in the MAC of the network camera, second preset first hotspot template information in the network camera, and predefined information in the network camera, where the way of generating the name of the second hotspot is the same as the way of generating the name of the first hotspot, which will not be described herein again.

[0083] The determining the password of the second hotspot based on the first shared key can include taking part of characters in the first shared key as the password of the second hotspot. For example, the first 8 characters in the first shared key can be taken as the password of the second hotspot, which is only an example, and the specific way of taking part of characters in the first shared key as the password of the second hotspot can be set according to actual conditions.

[0084] The taking the name of the second hotspot and the password of the second hotspot as the configuration information of the second hotspot can include taking the name of the second hotspot, the password of the second hotspot, and the attribute of the second hotspot as the configuration information of the second hotspot, where the attribute of the second hotspot can be a hidden state or a broadcast state.

[0085] By adopting the above scheme, the name of the second hotspot is determined based on the device information of the network camera; the password of the second hotspot is determined based on the first shared key; and the configuration information of the second hotspot of the network camera is determined based on the name of the second hotspot and the password of the second hotspot. In this way, the second hotspot password obtained according to the first shared key is known only to the screen terminal and the network camera, so that the security of network camera and screen terminal networking is improved.

[0089] The device information of the screen terminal is obtained by decrypting the second ciphertext data carried in the registration request based on the first shared key, including: decrypting the device information of the screen terminal by a decryption algorithm with the first shared key as a decryption key, where the decryption algorithm is the same as the encryption algorithm.

[0090] In an embodiment, in a case where the device information of the screen terminal is not obtained by decrypting the registration request based on the first shared key, it is determined that the screen terminal fails to be bound to the network camera, and the above process is re-executed.

[0091] The decrypting the registration request based on the first shared key to obtain the device information of the screen end can be: in a case where the first shared key is taken as a decryption key, the registration request is decrypted by a decryption algorithm, and the obtained decryption information is random code, it is determined that the device information of the screen end is not obtained.

[0092] In some possible implementation manners, on the network camera side, the response message of the registration request sent to the screen end comprises: encrypting the related information of the configuration information of the second hotspot based on the first shared key to obtain first ciphertext data; and sending the response message of the registration request to the screen end, wherein the response message of the registration request carries the first ciphertext data.

[0093] The related information of the configuration information of the second hotspot comprises one of the following: the name of the second hotspot, the password of the second hotspot; and the number of bits of characters in the first shared key corresponding to the name of the second hotspot and the password of the second hotspot.

[0096] In some possible implementation manners, on the screen end side, after the response message of the registration request sent by the network camera is received, the following step is further included: decrypting the first ciphertext data carried in the response message of the registration request based on the first shared key to obtain the related information of the configuration information of the second hotspot.

[0097] The decrypting the first ciphertext data carried in the response message of the registration request based on the first shared key to obtain the related information of the configuration information of the second hotspot comprises: taking the first shared key as a decryption key, and decrypting the first ciphertext data carried in the response message of the registration request by a decryption algorithm to obtain the related information of the configuration information of the second hotspot, wherein the decryption algorithm is the same as the encryption algorithm.

[0098] Optionally, the connecting to the network camera as the second hotspot based on the related information of the configuration information of the second hotspot comprises: connecting to the network camera as the second hotspot based on the name of the second hotspot and the password of the second hotspot.

[0099] Optionally, the connecting to the network camera as the second hotspot based on the related information of the configuration information of the second hotspot comprises: determining the password of the second hotspot in the first shared key based on the number of bits of the characters in the first shared key corresponding to the password of the second hotspot; and connecting to the network camera as the second hotspot based on the name of the second hotspot and the password of the second hotspot.

[0100] By using the above scheme, the network camera transmits the related information of the configuration information of the second hotspot in a manner of encryption by the first shared key, and the screen end obtains the related information of the configuration information of the second hotspot by decryption by the first shared key, so that the transmission of the related information of the configuration information of the second hotspot is more secure, and the security of the networking of the network camera and the screen end is improved.

[0101] In some possible implementation manners, after the connecting to the network camera as the second hotspot based on the related information of the configuration information of the second hotspot, the screen end further comprises: sending an update registration request to the network camera; receiving a response message of the update registration request sent by the network camera, wherein the response message of the update registration request is used to notify the screen end that the binding with the network camera is successful; and switching the binding state of the screen end from an unbound state to a bound state.

[0102] The switching of the binding state of the screen end from the unbound state to the bound state can comprise: modifying a first value of a factory mode in a factory partition of the screen end to a second value.

[0103] In the embodiment, the sending of the update registration request to the network camera by the screen end comprises: encrypting device information of the screen end by an encryption algorithm by taking the first shared key as an encryption key to obtain third ciphertext data; and sending an update registration request to the network camera, wherein the registration request carries the third ciphertext data. The manner of obtaining the third ciphertext data is the same as the manner of obtaining the second ciphertext data, which will not be described herein.

[0104] In some possible implementation manners, after the network camera is connected to the screen end as the second hotspot, the network camera side further includes: receiving an update registration request sent by the screen end; and sending a response message of the update registration request to the screen end, where the response message of the update registration request is used to notify the screen end that the binding with the network camera is successful.

[0105] The update registration information includes device information of the screen end, and is used for the network camera to register and record the device information of the screen end.

[0106] In the embodiment, the sending of the response message of the update registration request to the screen end includes: in a case where device information of the screen end is obtained by decrypting third ciphertext carried in the update registration request sent by the screen end based on the first shared key, the sending of the response message of the update registration request to the screen end. The decryption manner of the third ciphertext is the same as the decryption manner of the second ciphertext, which is not described herein again.

[0107] In a case where the device information of the screen end is not obtained by decrypting the third ciphertext carried in the update registration request sent by the screen end based on the first shared key, it is determined that the binding of the screen end with the network camera fails, and the above process is re-executed.

[0108] The case where the device information of the screen end is not obtained by decrypting the third ciphertext carried in the update registration request sent by the screen end based on the first shared key can be a case where, in a case where the decryption information obtained by decrypting the third ciphertext carried in the update registration request sent by the screen end based on the first shared key is garbled code, it is determined that the device information of the screen end is not obtained.

[0109] By using the above scheme, after the network camera is connected to the screen end as the second hotspot, the screen end determines that the binding of the screen end with the network camera is successful by sending an update registration request and receiving a response message of the update registration request sent by the network camera, so as to modify the binding state of the screen end. In this way, the binding state of the screen end and the network camera, that is, the networking state, can be determined more accurately.

[0110] The above embodiment is exemplarily described in combination with FIG. 4. As shown in FIG. 4, in a case where the IPC is an AP (Access Point mode) and the screen end is in an unbound state, the following includes:

[0111] S401, the IPC obtains device information of the screen end by scanning a two-dimensional code displayed on a screen of the screen end.

[0114] After the IPC generates the first hotspot, the IPC listens to a TCP (Transmission Control Protocol) connection initiated by the screen end through a port 8088.

[0140] In the embodiment, in a case where the first signature is verified to be passed based on the second shared key, the device information of the screen terminal, and the third public key, it is illustrated that the screen terminal is authenticated to be passed by the network camera, so that the screen terminal can be identified by the network camera, and access or use of related services and functions is allowed, otherwise in a case where the verifying is failed, the screen terminal is denied to access or use related services and functions.

[0149] In the case that the verification is passed, the third shared key is used to encrypt data transmission between the screen-side device and the network camera. In the case that the verification is failed, the above steps are re-executed.

[0150] By using the above scheme, the screen-side can determine the legality of the fourth public key sent by the network camera by verifying the response message of the login information sent by the network camera, so that in the case that the verification is passed, the third shared key is used to encrypt data transmission between the screen-side device and the network camera, and the security of data transmission can be improved.

[0151] The above implementation manners are exemplarily described in combination with FIG. 5, as shown in FIG. 5, which includes:

[0152] S501, the screen-side generates a third public key and a third private key of the screen-side;

[0153] S502, the screen-side signs the third public key of the screen-side and device information of the screen-side based on a second shared key to obtain a first signature, and sends a login request to the IPC, where the login request carries the first signature, the device information of the screen-side, the third public key, and the second shared key includes a first shared key or preset information.

If the verification of the first signature fails, the method proceeds to step 401 in the above embodiment.

[0155] S504, the IPC signs the fourth public key of the IPC based on the third shared key to obtain a second signature, and sends a response message of the login request to the screen end, where the response message of the login request carries the second signature and the fourth public key.

[0156] S505, the screen end generates a third shared key based on the fourth public key and the third private key, and completes the negotiation of the third shared key.

[0157] S506, the IPC and the screen end perform data encryption based on the third shared key to establish a data encryption channel, and encrypt data transmission between the screen end device and the network camera based on the third shared key.

[0158] In some possible embodiments, on the network camera side, the method further includes: in a case where it is determined to upgrade based on an upgrade notification sent by a server, obtaining an upgrade file corresponding to the upgrade notification from the server, and storing the upgrade file corresponding to the upgrade notification in a first partition of the network camera, where the upgrade notification includes an upgrade policy, and the upgrade policy includes one of the following: forced upgrade and normal upgrade; switching a startup partition mark of the network camera from a second partition to the first partition, and restarting the network camera; in a case where the network camera is successfully started based on the first partition, the network camera is upgraded successfully.

[0159] The upgrade notification can be sent by a server connected to the network camera. The server can also be referred to as a cloud. The network camera can be connected to the server as a STA.

[0160] The network camera as a STA can also be connected to a terminal, or the server can be connected to the terminal, and the specific connection manner is not limited here. The terminal can be a smart terminal, such as a smart phone, a tablet computer, or the like. The terminal is different from the screen end.

[0161] The determining whether to upgrade the network camera based on the upgrade notification comprises one of the following: in a case that the upgrade policy carried in the upgrade notification is a forced upgrade, it is determined to upgrade the network camera; in a case that the upgrade policy carried in the upgrade notification is a normal upgrade and a message confirming the upgrade of the upgrade notification is received from the terminal, it is determined to upgrade the network camera.

[0162] In an embodiment, the method further comprises: the server sending an upgrade notification to the terminal.

[0163] In a case that the terminal receives the upgrade notification sent by the server and the upgrade policy included in the upgrade notification is a normal upgrade, the terminal sends a message confirming the upgrade or a message rejecting the upgrade to the network camera based on the operation of the user in the terminal.

[0164] In a case that the upgrade policy included in the upgrade notification received by the network camera is a normal upgrade and the terminal does not send a message confirming the upgrade to the network camera or sends a message rejecting the upgrade to the network camera, the network camera continues to wait for the upgrade notification sent by the server next time.

[0165] In an embodiment, on the network camera side, the method further comprises: in a case that the starting of the network camera based on the first partition fails, switching the starting partition of the network camera from the first partition to the second partition and determining that the upgrade of the network camera fails.

[0166] The first partition of the network camera can also be referred to as the system backup partition of the network camera. It can be understood that the first partition of the network camera and the second partition of the network camera are system backup partitions of each other. For example, in a case that the current second partition is the starting partition (i.e., the starting partition is marked as the second partition), the first partition is the system backup partition. In a case that the upgrade file corresponding to the upgrade notification is stored in the first partition of the network camera, the starting partition mark of the network camera is switched from the second partition to the first partition, the starting of the network camera based on the first partition succeeds, the first partition is used as the starting partition and the second partition is used as the system backup partition, and the switching is repeated. In a case that the starting of the network camera based on the first partition fails, the network camera is started using the current second partition as the starting partition. This mode can also be referred to as a ping-pong upgrade mode.

[0167] By using the above scheme, it can be ensured that the network camera can be accurately upgraded according to the upgrade policy. According to the ping-pong upgrade mode, the stability of the upgrade of the network camera can be ensured, and the case that the network camera cannot be used after the upgrade due to errors in the upgrade process can be avoided.

[0168] In some possible implementation, the network camera side, the method further comprises: obtaining the version of the screen terminal; in the case that the version of the screen terminal is lower than the version of the network camera, determining the upgrade version of the screen terminal and the upgrade strategy corresponding to the upgrade version of the screen terminal based on the version of the screen terminal and the version of the network camera; sending an upgrade instruction to the screen terminal, wherein the upgrade instruction carries the upgrade version of the screen terminal and the upgrade strategy corresponding to the upgrade version of the screen terminal; in the case that an upgrade request sent by the screen terminal is received, sending the upgrade file corresponding to the upgrade version of the screen terminal to the screen terminal.

[0169] In the case that the version of the screen terminal is lower than the version of the network camera, the method of determining the upgrade strategy of the screen terminal based on the version of the screen terminal and the version of the network camera can be: in the case that the version of the screen terminal is lower than the version of the network camera and the difference between the version of the screen terminal and the version of the network camera is greater than a threshold, determining the upgrade strategy of the screen terminal as forced upgrade; in the case that the version of the screen terminal is lower than the version of the network camera and the difference between the version of the screen terminal and the version of the network camera is less than or equal to the threshold, determining the upgrade strategy of the screen terminal as normal upgrade.

[0170] In the case that the version of the screen terminal is lower than the version of the network camera, the method of determining the upgrade version of the screen terminal based on the version of the screen terminal and the version of the network camera can comprise: taking the version of the network camera as the upgrade version of the screen terminal.

[0171] In the case that the version of the screen terminal is higher than or equal to the version of the network camera, the method of determining that the screen terminal does not upgrade and does not send an upgrade instruction to the screen terminal.

[0172] By adopting the above scheme, whether the screen terminal upgrades can be determined according to the difference between the version of the screen terminal and the version of the network camera, so that whether the screen terminal needs to upgrade can be determined more accurately, and the upgrade efficiency is improved.

[0173] In some possible implementation, the network camera side, the method further comprises: sending the upgrade file corresponding to the upgrade version of the screen terminal to the screen terminal, comprising one of the following: in the case that the upgrade file corresponding to the upgrade version of the screen terminal exists in the network camera, sending the upgrade file corresponding to the upgrade version of the screen terminal to the screen terminal; in the case that the upgrade file corresponding to the upgrade version of the screen terminal does not exist in the network camera, obtaining the upgrade file corresponding to the upgrade version of the screen terminal from a server and sending the upgrade file corresponding to the upgrade version of the screen terminal to the screen terminal.

[0174] By adopting the above scheme, it can be ensured that the screen end can obtain the upgrade file corresponding to the upgrade version in time. When the network camera already has the upgrade file, the screen end is directly sent, thereby improving the efficiency of obtaining the upgrade file. When the network camera does not have the required upgrade file, the screen end can be actively obtained from the server and sent, thereby ensuring that the screen end can successfully obtain the corresponding upgrade file as long as there is an upgrade version, thereby realizing timely updating and optimization of the system.

[0175] In some possible implementation manners, on the screen end side, the method further includes: sending the version of the screen end to one or more network cameras; receiving an upgrade instruction sent by the one or more network cameras; in a case where it is determined to upgrade based on the upgrade version of the screen end included in the upgrade instruction of the one or more network cameras and the upgrade strategy corresponding to the upgrade version of the screen end, determining the target upgrade version of the screen end based on the upgrade version of the screen end included in the upgrade instruction of the one or more network cameras, and determining the target upgrade strategy corresponding to the target upgrade version, wherein the target upgrade strategy includes one of the following: forced upgrade and normal upgrade; sending a generation upgrade request to the network camera corresponding to the target upgrade version; and obtaining the upgrade file corresponding to the target upgrade version of the screen end from the network camera corresponding to the target upgrade version.

[0176] The determination of whether to upgrade based on the upgrade version of the screen end included in the upgrade instruction of the one or more network cameras and the upgrade strategy corresponding to the upgrade version of the screen end includes: in a case where the upgrade strategy corresponding to the highest upgrade version in the upgrade version of the screen end included in the upgrade instruction of the one or more network cameras is forced upgrade, determining to upgrade; and in a case where the upgrade strategy corresponding to the highest upgrade version in the upgrade version of the screen end included in the upgrade instruction of the one or more network cameras is normal upgrade, determining to upgrade based on a confirmation upgrade operation of a user in the screen end.

[0177] The method further includes: in a case where the upgrade strategy corresponding to the highest upgrade version in the upgrade version of the screen end included in the upgrade instruction of the one or more network cameras is normal upgrade, determining not to upgrade based on a refusal upgrade operation of a user in the screen end, and continuing to execute the above steps.

[0178] By adopting the above scheme, whether the screen end needs to be upgraded can be determined according to the version difference between the screen end and the network camera, so that whether the screen end needs to be upgraded can be more accurately determined, and the efficiency of upgrading is improved.

[0179] In some possible implementation manners, on the screen side, the method further includes: storing the upgrade file corresponding to the target upgraded version of the screen in a third partition of the screen; switching the boot partition mark of the screen from the fourth partition to the third partition, and restarting the screen; in a case where the screen is successfully started based on the third partition, the screen upgrade is successful.

[0180] In some possible implementation manners, on the screen side, the method further includes: in a case where the screen fails to be started based on the third partition, switching the boot partition of the screen from the third partition to the fourth partition, and determining that the screen upgrade fails.

[0181] The third partition of the screen can also be referred to as a system backup partition of the screen. It can be understood that the third partition of the screen and the fourth partition of the screen are system backup partitions of each other. For example, in a case where the current fourth partition is a boot partition (that is, the boot partition mark is the fourth partition), the third partition is a system backup partition. In a case where the upgrade file corresponding to the target upgraded version is stored in the third partition of the screen, the boot partition mark of the screen is switched from the fourth partition to the third partition, and the screen is successfully started based on the third partition, the third partition is used as the boot partition, the fourth partition is used as the system backup partition, and the switching is repeated. In a case where the screen fails to be started based on the third partition, the screen is started using the current fourth partition as the boot partition. This mode can also be referred to as a ping-pong upgrade mode.

[0182] By using the above scheme, according to the ping-pong upgrade mode, the stability of the screen upgrade can be ensured, and the case where the screen cannot be used after the upgrade due to errors in the upgrade process can be avoided.

[0183] After the screen upgrade is successful, the method further includes: determining whether the WIFI firmware of the screen needs to be upgraded according to the version information of the WIFI firmware of the screen and the version of the WIFI firmware of the network camera, and if so, requesting the network camera to download the corresponding WIFI firmware and calling the instruction to download. The specific determination mode and the downloading mode are the same as those of the screen, which will not be described here again. The firmware can include a driver.
