NVR 2.2 SP3 (V2.2.57) User’s Manual
11
System Requirements
The performance of NVR is largely determined by the hardware PC capability. The table below
provides basic guideline for selecting proper hardware. The minimum required hardware will
provide acceptable performance for systems that use mostly MPEG4 streams. Surveillance
systems that use primarily H.264 streams should satisfy Recommended PC Spec for good
performance.

NOTE:
Live view for multiple channels require good hardware for smooth performance. If your
live view performance is not satisfactory, please reduce the number of channels viewed at the
same time, and use Layout Tour to scan through all the channels instead.
NOTE:
When CPU power is not enough to provide smooth live view, NVR will decode only one
frame per second to save computing power. This is done to ensure that recording is always
properly processed. In extreme cases, like when viewing 64 Megapixel H.264 video streams at
the same time, PC will be overloaded and NVR will stop operation. This is a common limitation
imposed upon all Windows based video management programs. Enhancement for this
limitation will be available in the next version of NVR.
NOTE:
PC Spec requirements are the same for 32-bit and 64-bit systems.
