In terms of 

local display, the default stream 1 for live view can be configured with a 

resolution up to Full HD 30fps. Stream 1 is also a source for continuous recording. 

Make 

sure your cameras' 

stream 1 resolution does not exceed 1080P at 30fps.  

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.  

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: 

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.

If you configure a RAID5 volume as the recording storage, the maximum system throughput will
