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.
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)
■The names of the viewers have been changed as follows:

Viewer for Java
Viewer Overview
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.

There are two types of WebView Livescope Viewer Software: the Viewer for Java and the Viewer for
PC.

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.

Introduction

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.
c
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 VB-
C50Fi 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.

●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.

Preparations for Using the Viewer for Java
The Viewer for Java is automatically downloaded from the camera server. There is no need to install
it in advance. However, depending on the type of Web browser you are using and your software
settings, you must change your Web browser settings.
Using Internet Explorer
* For Internet Explorer 6.0
Internet Explorer has a setting that specifies whether the use of Java is permitted.
From the “Tools” menu, select “Internet Options” and click the “Advanced” tab. Then set “JIT
compiler for virtual machine enabled” as the “Microsoft VM” setting.
In Windows XP, Java VM may not be installed. If this is the case, please install it. See the
web site for more details.
WebView Product web site http://www.canon.com/webview
Detailed settings below similar to the ones are displayed after settings.

When You are Connected to a LAN
If the camera server is used via an Intranet and you specify the Web browser proxy
setting manually, videos are distributed via the proxy. This can result in a slower
frame rate and proxy server overload.
Use the procedure shown below to set up a “No proxy” connection. Note that if
you are accessing a camera server that is located outside a firewall on the internet,
registration is not required for the camera server.

Starting Camera Control
Although multiple clients can simultaneously connect to the camera server, multiple clients
cannot simultaneously control the camera. Consequently, “control privileges” has been
introduced by which only the client who currently holds the control privileges can control the
camera. Backlight adjustment and presets can also only be used when you have control
privileges.
Procedure
