Bandwidth Limitation

The maximum bandwidth throughput capacity is 80 Mbps for the VMAX IP® Plus NVR and 160 Mbps for the 3rd and 4th generation 16 channel NVRs.If you are receiving a “Bandwidth Limit Error” message on your VMAX® IP Plus, the total throughput of all cameras connected with your NVR is exceeding the limitation. This may cause issues with capturing video within the system, camera connection errors, and other issues for the recording unit.

This article will outline how to adjust the bitrate for each connected camera through the user interface of the VMAX® IP Plus.

Supported/Affected Devices:

VMAX® IP Plus Series

Checking Current Bandwidth

If you are currently logged into the VMAX® IP Plus, you can check the current bandwidth usage of the recording unit.

To do so:

From the system’s Live View, right-click with the connected USB mouse and select System Status.

Within the System Status window, locate Receive Data.

If the current bandwidth usage exceeds the limitation of the NVR, you will need to adjust the camera bitrate settings within the system to resolve your issue.

Adjusting Camera Bitrate Settings

To adjust the camera bitrate, perform the following directly at the VMAX IP® Plus recording unit:

From the Live View, right-click on the camera and select “Camera Setup”.
Adjust the bitrate of the Rec. Stream.

Click the Get Stream button, then click the Setup button for the Rec. Stream (primary).

Adjust the Bitrate of the Rec. Stream (primary) so that it falls between 4000 ~ 6000 Kbps, then click the Apply button.

Adjust the bitrate of the 2nd Stream.

Next, click the Setup button for the 2nd Stream (secondary).

The IP Camera Stream Setup window for the secondary stream will display. It is recommended to keep the Bitrate to 1 Mbps or lower per channel.

Adjust the Bitrate of the 2nd Stream (secondary) to 1000 Kbps or lower, then click the Apply button.

**NOTE: Repeat this process for all cameras.

How to Lower the Camera Bitrate with Web Viewer

If you are using the NVR’s Web Viewer to adjust the camera bitrate:

Click on the Setup tab, then select “Record”.

Click on “Camera Management”, then click on the Setup button for the desired camera.

Adjust the Bitrate of the primary stream so that it falls between 4000 ~ 6000 Kbps
Adjust the Bitrate of the secondary stream to 1000 Kbps or lower.

**NOTE: If the issue persists after performing all troubleshooting steps that are listed above, please proceed with running recovery firmware on the VMAX® IP Plus.

Any issues after this should be reported to Digital Watchdog Technical Support for further assistance.
