The following briefly describes how the network image manipulation device 200 obtains the public network address used by the network address translation host 300 by using the UDP simple traversal protocol. The coffee-,., and weekly image capturing device 200 shown in FIG. 5 generates a packet 2〇1 for inquiring the public network address and transmits it to the network address W矣 host 300. After receiving the packet 2Q1 of the public network bit ^, the network address translation host 3 will change the source network address in the packet 2〇1 to the address itself to generate a new packet. 1, then transfer the packet 3〇1, The shell lion covers the host 41〇 (that is, the UDp fresh wear: after receiving the packet, the reply host 410 will convert the public network address used by the host 300 by the address 301; After the location 10 200824344 = is returned to the network address translation host 300, the network address translation = Γ after receiving the packet 401, the packet 401 is decapsulated to know that the content in the packet is to be forwarded to the network image. The device 200 is operated, so that the packet/towel bag 302 is re-encapsulated, and the scale-pulse device can know the public address of the network address converted by the user (10) after receiving the packet 302 (4) In the installation, please obtain the public network address (that is, the public network address 61.229.13.2 will be displayed on the If device __ red, _ _ _ _ _ _ _ _ _ second authorization code And displaying the second authorization code on the liquid crystal display (step 730, step 74ΓΠ, αϊι step 740), for example, 1234, so that the user does not have to perform additional operations to know that the current public network address is l. ^13·2 'When the extra-operative (four) drink is recorded on the display, what is the use, the road address 61_229 13·2 and the authorization code are still 4. Among them, the method of producing the second grant # code of the present invention is secretly generated randomly, and other methods such as the specific measurement can also be After the horse user is out, if you want to watch the network image capture, you can find the remote computer that connects to the Internet 4〇〇, because For example, the service program is a network uniform program. Therefore, the user needs to execute a program that can browse the web page to enable the service provided by the __ service program. Therefore, the user needs to select the location of the input URL in the interface provided by the network program. When you enter the public network address 61 · 229 13 · 2 recorded when you go out, the remote computer will connect to the network using the public address of 61.229.13.2 through the 4QQ.

Secondly, the page displayed by the program displayed on the page of the page is written by the user who signed the code. The remote computer 500 will transmit through the connection with the network address. The signal and the request of the authorization code 1234 input by the user are sent to the network address conversion host 300 (step 750, step 76), so that the webpage server executed by the processor 23 receives the authorization of the user input. Code 1234. After the webpage value program receives the authorization code of the user input, the web feed program compares with the first authorization code 1234 input by the user and the generated second authorization code 1234 (step 77〇), if used The first authorization code 1234 is the same as the generated second authorization code 1234, and the webpage server will receive the image signal generated by the image capturing device 210 and transmit the image signal to the network address conversion. The host 300, the network address conversion host 3〇〇 will forward the scene record signal to the remote host 5〇〇 through the network (step); if the two authorization codes are different, the end-to-end host 5QQ request is rejected. To the remote host 5QQ. Therefore, the present invention can solve the problem that the user mentioned in the prior art cannot know the non-fixed network address or need to transfer the video signal through the additional server. In the above example, the network image capturing device 2Q0 and the network address translation host 300 do not need to be connected through the network route, because the data transmission interface 220 in the network image capturing device 200 includes the wireless network. The road module 222, the wireless network 12 200824344 module 222 can be a Wi-R module, a Bluetooth module, etc., so the network image device 200 can be switched to a wireless network such as Wi-Fi or Bluetooth. Connected to the network address translation host 300, in the case of Wi-Fi, the user needs to have an access point (AP), and the access point is connected to the network 300 through the network route. When the network image manipulation device 2 uses the wireless network technology, the wireless network module and the group 222 are connected to the access point, so that the image signal of the network image capturing device 200 can be accessed through the access point. Arriving at the network address to convert the host, and the network address conversion host forwards the image signal to the remote computer. If the user wants to use the technology to transmit the video signal, the _ road address conversion host 3 needs to have a Bluetooth receiver (adapte〇 or Bluetooth receiver and network address conversion host 3GG chick, so that the remaining image is captured When the device is configured to transmit the image signal, the Bluetooth receiver can transfer the received image signal to the network address conversion host 300. The data transmission interface of the network image capturing device 200 has a universal string. The busbar (Umversa丨Se "ia丨Bus; USB) can make the near-end computer coffee that is also in the network address conversion host 4 side connect to the network shadow axis taking device by using the universal string ship's connection cable.
