The information stored in the associated data table 533 includes the number of data, the user identification code, the network device identification, and the code for recording the association information between different users and the network devices to which they are connected. Since the network camera 41 has been registered in the server 5 first, after the server 5 confirms, a notification connection message is sent to the network camera 41 (step 111). If the request from the client 1 is to be connected to the webcam 42 that has not been registered, the server 5 will not accept the request. Finally, after receiving the notification connection message, the network camera 41 connects to the user terminal 1 through the firewall 3 and the Internet 2, and transmits the target data S3 to the user terminal 1 under the network data transmission protocol P. (Step 112). The target data S3 represents the sound and image data of the network camera 41 in this embodiment, that is, by the above method, the user terminal 1 can directly view the image taken by the network camera 41. Referring to Fig. 6, there is shown an architectural diagram of an access control module of a second embodiment of the present invention. Since the system architecture of the second embodiment of the present invention is the same as that of the first embodiment of the servo circuit. Only the structural design of the access control module 6' is different, so the same components are denoted by the same component numbers. The difference is that the access control module 6' of the second embodiment has a User Datagram Protoco (UDP) transmission module 67. The user data packet transmission module 67 is connected to the message processing module 65 for use in performing UDP transmission. -11 - 201008199 Referring again to Figures 7 and 8, there is shown a transmission timing diagram and a control flow chart of the second embodiment of the present invention. The second embodiment of the present invention is executed in a certain program flow to F:, 2. Similarly to the first embodiment, the network camera 41 transmits a registration request message to the server 5 (step 201). The server 5 receives an authentication request message and returns an authentication message to the network camera 41 (step 202). When the network camera 41 receives the authentication message, it returns a reply authentication message to the server 5 based on the random number (step 203). After receiving the reply authentication message, the server 5 returns a confirmation reply message to the network camera 41 (step 204). The network camera 41 transmits a network device registration data S1 to the server 5 through the firewall 3 and the Internet 2 (step 205). In the access control module 6', the network device registration data S1 is sent from the application program A under the network data transmission protocol P, and then through the network data transmission module 61, the device control module 63, and the data inventory modulo The group 66 is stored in the network device data table 531 of the database 53 (step 205). Before the user terminal 1 wants to connect to the network camera 41, a user registration data is sent to the server 5 (step 206). The server 5 stores the user side registration data in the user side data table 531 of the database 53 of the server 5 (step 207). After the registration is completed, the client 1 sends an access message S2 to the server 5 (step 208). The server 5 receives the access message S2 sent by the user terminal 1, and confirms whether the network camera 41 has been registered with the server 5 in response to the request of the access message S2 (step 209). After confirming that the network camera 41 has been registered, the server 5 transmits a notification connection message to the network camera 41 (step 210). -12 - 201008199 rl Listening to the camera 41 _ notification connection 3 and the Internet 2 and _ 5 μ ^ through the fire, (four) (four) μ line, in the network data transmission protocol p to the servo-5 II, to the gamma ^ 5 (step 211).
