Introduction This manual describes how to use the WebView Livescope Ver. 3.20 Viewer software. The two types of viewer are Java viewers and the Helper Viewer, and the video 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.
Overview ■ WebView Livescope is the system that allows camera control and live video distribution from a remote location. ■ The system is configured of a camera server and viewer software. The camera server distributes live videos taken by the video camera to the Internet or an Intranet. The viewer software can display those videos and remotely control the camera.
Viewer Overview There are two types of WebView Livescope Viewer Software: the Java Viewer and the Helper Viewer. Java Viewers These are viewers written using Java. These viewers allow the camera server 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, but there is no need to pre-install the viewer on your computer.
Helper Viewer This is a viewer that runs as a helper application. This viewer provides video display and camera control functions and appears in a separate window at startup. While the Helper Viewer 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.
Operating Environment Java Viewer Ver. 3.20 Web Browser A Web browser that runs Java. Microsoft Internet Explorer 4.01 or later recommended. Netscape Navigator or Communicator 4.78 or later recommended. (excluding 6.01 and 6.1) Computer Operating System IBM PC/AT Conpatible Windows 98 Second Edition, Windows Me, Windows NT 4.0 (requires IE 4.01 or later), Windows 2000, Windows XP * This viewer is installed in the camera server and automatically downloads to the client when accessed.
Chapter 1 Java Viewers This chapter describes the preparations required for using the WebView Livescope Java viewers and explains how to use the viewers.
Preparations for Using the Java Viewer The Java Viewer 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 Internet Explorer has a setting that specifies whether the use of Java is permitted. From the "View" menu, select "Internet Options" and click the "Advanced" tab.
e When You are Connected to a LAN Note 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 Up the Java Viewer The Java Viewer is started up from the Web browser that displayed the Web page for distributing videos. To create a Web page for distributing videos, refer to Chapter 5 of the User's Manual for the camera server. When the "Using Java Viewer" button in the Web Browser that displayed the Web page for distributing videos is clicked, the Java Viewer starts up and connects to the camera server.
Using "LiveApplet" "LiveApplet" is a viewer with a GUI that allows the user to change the camera angle, zoom ratio and backlight adjustment settings. "LiveApplet" Screens The functions of the GUI displayed on the Web browser are briefly described below. 1 1 2 Java Viewers 3 4 5 11 1 10 9 8 7 6 Reduce resolution button and Increase resolution button The right-hand button makes the displayed video source one level smoother, while the left-hand button makes it one level coarser.

Using "LiveApplet" c Note Customizing the Viewer Screen The function buttons and other aspects displayed in the Java Viewer can be customized according to camera server settings. Functions restricted by the camera server can be customized so that they are not displayed, or they may be made to be displayed in a different way according to the setting. For details, refer to the User's Manual of the camera server.
Using "Glimpse" The "Glimpse" viewer is a light-weight Java viewer. It has a short download time as it has no camera control functions and only displays video images. This viewer is useful for viewing videos from multiple sites, as shown below.. "Glimpse" Screen The Glimpse viewer is used only for viewing videos; it does not include camera control functions.
Chapter 2 Helper Viewer This chapter describes the preparations required for using the WebView Livescope Helper Viewer and explains how to use the viewer.
Preparations for Using the Helper Viewer Difference between 2 Helper Viewers There are two types of Helper Viewers: the Helper Viewer that is packaged with the Network Camera Server VB101 and the Network Camera VB-C10/VB-C10R, and the Helper Viewer that can be downloaded at no charge from the WebView World Web site. Hereafter, they were will be referred to as the "VB Package Version" and the "Download Version". The "VB Package Version" includes all the functions of the "Download Version".
