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 DVR in a
network-sensitive environment and prohibits the DVR from sending a large
amount of network data that can potentially disrupt the network.
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.
Only the administrator can modify this function.
To modify the network throttle:
1. Click the System Settings icon in the menu toolbar and then click Net
detect.
2. Select the Network Stat tab.
