Using the Helper Viewer to Transmit Video Images
This section describes how to use the Helper Viewer to provide video images. Application examples are
also given.
If a client is using the Helper Viewer to transmit video images, the sender must set up the Web server and
create the necessary wvh files.
e
Tip
If the VB101 is used as the Web server, the settings described below are not required.
Setting Up the Web Server
Set up the Web server to be used for saving the data transmission Web page. Add the MIME type
to the Web server software and specify the extension. Refer to the manual for your Web server
software for details.
MIME type video/x-webview-h
Extension wvh
For Apache
In the settings for added the MIME type in Apache,
edit the "mime.types" file in the "conf" directory.
■Use the following syntax to add the required MIME type to the computer:
type/subtype extention
■The settings for WebView Livescope are as follows:
video/x-webview-h wvh (Helper settings)
Creating wvh files
This section describes how to create the wvh file required for launching the Helper Viewer application.
Use a text editor or similar program to create a new text file and type the following type of
code in the file:
192.168.100.1 65310
192.168.100.1 65311
wvhttp:192.168.100.1 80
(Example)
● The first line gives the IP address (or host name) of the camera server and the TCP port
number used for the image transmission service.
For WebView Livescope, the default setting is 65310. The default setting will be used if
no particular value is specified.
● The second line gives the IP address (or host name) of the camera server and the TCP
port number used for the camera control service. For WebView Livescope, the default
setting is 65310. The default setting will be used if no particular value is specified.
● The third line gives the setting for the Helper Viewer to use HTTP protocol. After
"wvhttp:", type in the IP address of the camera server and "80" as the HTTP port
number. As a result of this, you will be able to view images from the camera server
through firewalls.
* Type in the actual IP address (or host name) of the camera server.
After you save the text file and quit the text editor program, create a wvh file by changing
the file name and extension. Be sure to add the ".wvh" extension, as in "Webview.wvh".
File names can contain up to 8 characters. (eg. WebView)

Note
If the MIME setting is not specified correctly for the Web server, you may not
be able to launch the helper viewer. Be sure to specify the setting.

Tip
Helper Viewer supports WebView Livescope protocol and HTTP protocol.
● WebView Livescope protocol: Cannot be viewed through firewalls. This
protocol is primarily for clients who are connected directly to the Internet.
● HTTP protocol: In general, this protocol is used with Web browsers. Images
from clients inside firewalls can also be viewed by using this protocol.
