4.It is important to ensure that the live viewing and recording configuration does not exceed the system's limits:
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.
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:
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.
