I'm unsure. I can tell you that with:
1x of my 3mp cameras enabled (running at 1280x720, 30fps) I'm running at 11Mbps on network /O, 62% memory and 15% CPU.
2x 3mp cameras running (both same resolution as prior) I run at 17MBps network I/O, 25% CPU.
3x Cameras: 38% CPU, 25Mbps Network I/O.
4x (last camera is a 3mp Arecont) I'm at 47% CPU, 33 Mbps network I/O.
All cameras (11 total) is 78% max CPU, 55 Mbps network I/O.
The memory I can't tell you accurately because it only thinks I have 4GB, and I'm not sure if the usage reflects 4GB or 12GB.
