The NVR supports Auto Stream Size, which automatically adjusts streaming display for efficient leverage of system resources. If you disable the Auto Stream Size function and manually configure your stream settings, you must comply with the limitations listed above.

IMPORTANT:

You may need to configure a recording stream of a particular resolution and bit rate. When doing this, you should make sure the Recording load does not exceed the maximum 96Mbps as the sum of bit rates per second allocated for all recording streams. If you have multiple cameras and the upper bound is exceeded, proceed with the following:

If you configure a RAID5 volume as the recording storage, the maximum system throughput will be reduced to half of the 96Mbps limitation.

Configure the Recording setting in Configuration > Camera Management > Update Camera. When the Update window prompts, select a camera. Click on the Recording Settings tabbed menu, and select a smaller stream (in higher or lower bit rate or resolution) as the source of recording. Click Update to save your configuration and repeat the setting until the recording load is back within the 96Mbps limitation.
