7.2.6 Remote View Using i-mode

I-Mode is a mobile Internet service that was first introduced by NTT Docomo of Japan.Currently i-mode services are only available in Japan and Taiwan. But since i-mode is one of the most successful mobile Internet solutions and NTT is aggressively introducing I-mode solution to other countries, therefore, it is possible that it will be available in other countries in the future.

GV-System's i-mode concept

When using i-mode services, you do not pay for the time you are connected to a website or service, but are charged only according to the volume of data transmitted or received. Therefore, GV-System does not send live videos, instead, it will only send one images at a time and will not send another unless it is requested to do so. To request another image simply press the [Enter] key of your I-mode phone and you will be able to receive another image from the system. The images are in GIF format with size of 96x72.

Enable GV-System's i-mode function

From your GV-System's main screen click [Network] > [WebCam Server] and enable "Support i-mode client". Your GV-System must be using a global IP address and should be accessible from the Internet.

Connect to GV-System using i-mode

After enable the i-mode function you can now receive live images from the GV-System via an i-mode mobile phone. The interface and operation of your I-mode phone maybe different from the following example since the interfaces may vary from models to models.

1. Enter to the I-mode service page of your I-mode phone.

2. Select "Input web address" and enter the IP address of your GV-System in the Address column then press [OK].

3. Input an valid user's name and password then press [Submit]

4. Select the camera you wish to view then press [Enter].

5. If login successfully you I-mode phone will be able to receive live images from the GV-System

7.3 DMIP System

If your GV-System is using a dynamic IP address then it is nearly impossible for WebCam users to locate your GV-System once its IP address changes. DMIP is exclusive developed application for solving such problem. DMIP utilizes standard File Transfer Protocol (FTP) to upload files or data to a designated file server. This allows IP address of the GV System to be transferred to the file server periodically. You can now logon to the file server instead of GV System, file server will further redirect WebCam viewer to the GV-System.

DMIP System Concept:

There are 3 major components required in the DMIP concept, which are DMIP-Server, GV-System, and client PC with web browser.

DMIP Server: Act as the FTP server and web server. This server must have a static IP address. You can setup your own DMIP Server or you can use the one already setup by us.

GV-System:       The GV-System should be installed with DMIP application. The GV System does not require to having static IP address and should be connected to the network by TCP/IP connection.

The client PC: Should have Internet access with either Microsoft Internet Explorer or Netscape Navigator installed.


DMIP Setup:

1. Install DMIP application in GV-System. Insert GV-System CD into the CD ROM drive of your GV-System and run Setup.exe in the CD root directory.

2. In the setup dialog box select "Register Dynamic IP" and click [Next] then follow the rest of the instruction to complete the installation.

3. Run DMIP application in GV-System. Please go to [Start] > [Program] > [DMIP] > [Register Dynamic IP] and the DMIP setup window will appear.

A: Input the host name of your GV-System. (The host name will be used for identifying your GV-System in the DMIP server.)

B: Click "Use Default". This will set the upload IP address to a public DMIP Server. You'll notice that the FTP Login parameters are closed and you will not be able to make any changes or modifications.

C: Click OK and the status window should display the date, time, and the connection status.

4. If the connection between GV-Server and Geo-Server is establish successfully, you'll be able to see a DMIP icon located in the lower left corner of the Window status bar.

Setup DMIP server

However, if you would like to build up your own DMIP server, please refer to the following instructions to set it up:

1. Execute the IIS server 5.0 embedded in the Windows 2000 Server.

2. Build up a FTP server and allow the "Write" function.

3. Build up a Webserver and specify the path to the one which the FTP server specified. Remember, the access with "Write" is not allowed to be activated.
 

Note:

If necessary, you may also write a homepage for your own DMIP server.
