Network Camera Server VB101

VC-C4COMMUNICATION CAMERAf:4-64 m 1:1.4-2.8Web Pages for Video TransmissionWeb Pages for Video TransmissionTo transmit picture data by VB101, you create a dedicated web page. The viewers that can be used withthe VB101 are "Java Viewer (with or without camera control function)" and "Helper Viewer", and detailedparameters can be specified for each of these. The person sending the data determines which of theseviewers is supported and must create the Web page for the viewer.DedicatedWeb server or VB101Features of the Java ViewersThese viewers are supplied as Java applets. They run on Web browsers that are Java-capable,such as the Netscape Navigator and Microsoft Internet Explorer browsers. The applets aredownloaded from the camera server to the Web browser and are then run by the Web browser. Thefeatures of the Java Viewers are described below.HTTP (WWW) serverInternet1 Access to Web pages2 IP address information notificationVideo transmission and camera operation using the WebView-HTTPprotocol. Penetrate firewalls to access external sites.Because they are automatically downloaded, the Java Viewers do notneed to be pre-installed by the client.Java Viewers run on a wide variety of platforms .3 Request for videoVB1014 Video transmissionViewer PCIf you select a link requesting video in step , a file that includes the IP address information for theVB101 is sent from the Web server in step . If you are using the Java version, the applet isdownloaded to the viewer PC from the VB101 in response to the request in step and the videorequest is then initiated.cNote● File NamesThe VB101 can handle file names consisting of up to 8 characters followedby a 3-character extension. Note that the names of applets built into theVB101 are exceptions to this rule.● Refer to step 3 on P.25 for information on saving content.eTipJava Viewer TypesTwo Java Viewers are "LiveApplet", which has video display and camera control functions, and"Glimpse", which only has video display functions. Because both viewers use WebView-HTTP asthe transfer protocol, they do not require special settings to penetrate firewalls.■Viewer TypesBecause the Java applets are downloaded using the HTTP protocol when theviewer starts up, the start up time is longer than the Helper Viewer.4Creating Web PagesViewer NameFunctionsDisplays video images from the camera server.eTipYou can use the Language setting function for the Browser to create a multilingualWeb site. For example, if you set the French-language top page asindex-fr.htm and the English-language top page as index.htm and supplyusers with a URL address terminates in slash, such as http://vb101/sample/,the server will transmit a file that corresponds with the language setting forLiveAppletGlimpseAllows camera control.Allows overlays and superimposition of bitmaps in the video frame.Because video is not displayed until the viewer has finisheddownloading, video display takes longer than with the Helper Viewer.Allows the video transmission interval to be set.Downloading is fast because it has only simple functions and is small.the Browser.
