sender can use one or the other as required. Both types provide the same basic
functions for viewing videos, but differ in terms of other features and functions. The
preparations for using the two viewer types and the required operating environment also
differ depending on the computer hardware and software used to run the viewer.
Read this manual carefully before you use the viewer to ensure that you make the best
possible use of this product.
Store this manual in a safe place after you finish reading it.
The latest information on the viewer is available at the following URL.

WebView Livescope Overview
■ WebView Livescope is the system that allows camera control and live video distribution from a
remote location.
■ The system is configured for a camera server and viewer software. The camera server distributes
live video taken by the video camera to the Internet or an Intranet. The viewer software can display
the video and remotely control the camera.
■ The WebView Livescope system can be used in a wide range of applications such as distributing
live video from a Web site and monitoring.
Introduction
The following types of camera servers are available:
• Network Camera Server VB150
• Network Camera VB-C50i/VB-C50iR
• Network Camera VB-C50Fi
The following types of Viewer Software are available:
• Viewer for Java (This manual: provided free of charge with camera server product)
• Viewer for PC (This manual: provided free of charge with camera server product)
• Network Video Recorder VK-64 (Sold separately)
• WebView Livescope MV Ver. 2.1/LE (Sold separately)
WebView Livescope is a video distribution system that enables users to
actively (by performing operations by oneself) view live (showing now) video
from Web pages by allowing users to change camera angle and zoom magnification.

Viewer Overview
There are two types of WebView Livescope Viewer Software: the Viewer for Java and the Viewer for
PC.
Viewer for Java
This is a viewer written using Java. This viewer allows the camera server’s videos to be
viewed on any computer with a Web browser that runs Java, regardless of the platform.
Because the Java applet is downloaded when the viewer starts up, the first video takes
some time to appear. The Viewer for Java provides two types of viewers: LiveApplet
containing video display and camera control functions, and Glimpse containing a video
display function.

Note
● To use the Viewer for Java, you need to install Java VM beforehand. See the
web site for more details.
WebView Product web site
http://www.canon.com/webview
● Panorama pictures must be registered in advance at the camera server.
* Panorama pictures are not available with the VB-C50Fi.

Viewer for PC
This is a viewer that runs as an application. This viewer provides video display and camera
control functions and appears in a separate window at startup. While the Viewer for PC has
to be pre-installed, it offers the advantage of displaying the first video quickly. At present,
only a Windows version of this viewer is available.

Note
● The Viewer for PC is provided on the CD-ROMs supplied with the Network
Camera Server VB150, the Network Camera VB-C50i/VB-C50iR and VBC50Fi packages. The viewer can also be downloaded free of charge from
the following web site.
URL : http://www.canon.com/webview
● The Viewer for PC needs to be pre-installed on your computer. (→ p.26)
● Panorama pictures must be registered in advance at the camera server.
* Panorama pictures are not available with the VB-C50Fi.
● When playing back audio, please read carefully “Usage Notice of Audio”
(→ P.4).
* Audio input/output is not available with the VB-C50Fi.
e
Tip
● Because the Viewer for Java is downloaded from the camera server every
time you access and displays video on the viewer screen, it starts up
slower than the Viewer for PC that is pre-installed on a PC.
● Use the Viewer for Java when you access the camera server and view video
for the first time. However, we recommend you to install and use the Viewer
for PC if you view video frequently.

Chapter 3
Viewer for PC Settings
This chapter describes how to specify the software environment settings for
the Viewer for PC.
Viewer for PC Settings
From the “Setup Properties” window, you can specify a range of settings governing the operation of
the Viewer for PC. Normally, there is no need to alter these settings.
“Starting protocol” Setting
Specify whether connection to the camera server is to be made using the WebView-TCP
protocol or the WebView-HTTP protocol.
Procedure
1
Select “Setup Properties” from the “View” menu.
2
Select protocols from the “Options at starting with WVH file” in the “Starting protocol” tab.
● “Auto select connection”
Use this setting when you do not know
the details of the connection
environment. When this option is
selected, the viewer first tries to connect
using WebView-TCP and then tries
WebView-HTTP.
● “WV-TCP protocol connection”
This setting uses the WebView-TCP
protocol used specifically by WebView
for TCP connections. To penetrate
firewalls with this protocol, a dedicated
application gateway is required.
● “WV-HTTP protocol connection”
This setting uses the WebView-HTTP protocol, which is the WebView protocol that conforms
to the ordinary HTTP standard. The HTTP proxy can be used as is and the firewall can be
passed.
● “Receive audio data”
Remove the tick if you do not want to receive audio data.
c
Note
44
Viewing video from behind a firewall
To view video from behind a firewall using the WebView-HTTP protocol, you
must specify the HTTP proxy settings. You can set the same settings as the
HTTP proxy specified in your Web browser. If you want to access video from
behind a firewall, select WV-HTTP protocol. (See P.45 for details.)
“HTTP protocol” Setting
Specify these settings when you are connecting using the WebView-HTTP protocol.
Procedure
1
Select “Setup Properties” from the “View” menu and then select the “HTTP protocol”
tab.
Enter each item. To automatically
import Internet Explorer HTTP proxy
settings, click “Acquire IE proxy
settings”.

Viewer for PC Settings
■ Use automatic configuration script
Tick if you want to use the automatic configuration script. Once ticked, enter the URL
of the Settings file in the “Address” field.
■ Use WV-HTTP proxy
[WV-HTTP proxy server]
Tick if you want to use an HTTP that uses a proxy. This then allows you to penetrate
firewalls. Once ticked, enter the domain name or IP address of the HTTP proxy
server host in the “Host” field, and enter the port number in the “Port” field.
[Do not use the proxy for local hosts]
Tick if you want to connect to local addresses without using the proxy.
[Set hosts not using proxy]
You can set up servers that can be accessed without using a proxy, not to use a
proxy. In this field, enter the domain name or IP address of the host that does not
use a proxy. To specify multiple hosts, use a comma (,) to separate the
specifications.
e
Tip
You can use asterisks (*) as wildcards in the host name in the “Set hosts not
using proxy.” setting. This allows you to specify multiple host names at once.
(Example)
192.168.100.*
Hosts with an IP address that begins with “192.168.100.” do not use the proxy.
*.webview.co.jp
Hosts on the network with the “webview.co.jp” domain name do not use the
proxy.
