Chapter 5: Using the Web browserFigure 19: Bandwidth control switchBandwidth throttle managementThe Bandwidth Throttle Management function lets you throttle the amount ofnetwork data sent from the DVR to a client. This function is helpful for networks thathave predefined bandwidth limits. This feature lets you control the TVR 30 in anetwork-sensitive environment and prohibits the TVR 30 from sending a largeamount of network data that can potentially disrupt the network. To configurebandwidth throttle, see “Advanced IP settings” on page 66.Both live dual streaming and bandwidth throttle management can be usedsimultaneously or individually. For example, if you display live video in the Webbrowser with the bandwidth throttle management feature enabled, the video updaterate is lower, as network video data is sent in shorter, controlled amounts. However, iflive dual streaming is enabled, then the video quality increases, since the secondstream can be reduced to meet the bandwidth throttle settings, which results in ahigher video update rate.Controlling a PTZ camera in the Web browserThe Web browser interface lets you control the PTZ functions of a camera.
