I have a standard dual core XP machine with 16 cameras feeding 2-3mb/s ea at 30fps. I think the specs are as follows:
500GB Std 7200 rpm WD Hard Drive
Pentium Dual Core Basic w/ 3ghz cores
2GB Std Memory
Cat 6 network bringing in the Camera data.
Computer is both showing data in real time and recording.
CPU running @ 100% all the time... where are the most likely bottlenecks, and the best things to look at when selecting a computer upgrade.
