4. It is important to ensure that the live viewing and recording conguration does not
exceed the system's limits:
In terms of local display, the default stream 1 for live view can be congured 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
efcient leverage of system resources. If you disable the Auto Stream Size function and
manually congure your stream settings, you must comply with the limitations listed above.
You may need to congure 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:
Congure the Recording setting in Conguration > 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 conguration and repeat the setting
until the recording load is back within the 96Mbps limitation.
