Bandwidth throttle management
The Bandwidth Throttle Management function lets you throttle the amount of
network data sent from the DVR to a client. This function is helpful for networks that
have predefined bandwidth limits. This feature lets you control the TVR 30 in a
network-sensitive environment and prohibits the TVR 30 from sending a large
amount of network data that can potentially disrupt the network. To configure
bandwidth throttle, see “Advanced IP settings” on page 63.
Both live dual streaming and bandwidth throttle management can be used
simultaneously or individually. For example, if you display live video in the Web
browser with the bandwidth throttle management feature enabled, the video update
rate is lower, as network video data is sent in shorter, controlled amounts. However, if
live dual streaming is enabled, then the video quality increases, since the second
stream can be reduced to meet the bandwidth throttle settings, which results in a
higher video update rate.
Controlling a PTZ camera in the Web browser
The Web browser interface lets you control the PTZ functions of a camera. Cameras
with PTZ capabilities are marked with a PTZ icon (as shown in Figure 19 on page 45).
