Chapter 1 System Overview
Chapter 1-1 System Requirements
The IP Camera’s H.264 AVC video compression technology can provide
high compression rate and superior video quality. However, the
performance highly depends on both CPU computational power of a client
PC and the network bandwidth for transmitting video streaming. The
following sections specify system requirement for running H.264 AVC:
Chapter 1-2 Number of Video Clients Allowed Running on a PC
If bandwidth is sufficient, number of H.264 AVC software decoder for
decoding H.264 AVC streaming at full D1 resolution running on same PC is
benchmarked as in the following figure:
CPU
Number of
H.264 AVC decoders
Resolution
Intel Pentium 4 1.80GHz
1 Full
D1
Intel® Core™ 2 2.33GHz
4 Full
D1
Chapter 1-3 Minimum Bandwidth Requirement
Please reserve 20% more bandwidth for specified bit rate. For example, if
the video streaming bit rate control is set to 1 Mbps. The network should
reserve at least 1.2 Mbps bit rate to gain maximum performance. Number
of client connections allowed at 1Mbps (upload and download) is calculated
as:

If your application is running for both Internet and LAN, it is highly
recommended to use JPEG encoding for Internet, especially very low bit
rate environment. It can maximize H.264 AVC video quality for LAN
application.
