Im considering buying the following rig:

6 cam
USB 3.0 pcie card
ssd Ocz vertex 2 (write 270 mbps)

But my processor is an i7 930 quad core... so 4 cam@640*480*60fps or 6 cam@320*240*60fps?
Or even 6 cam@640*480 but a lower frame rate?
What about 5 cameras?
If I overclock my processor should I get a sensible better capture performance?

Thanks!

iPi's official specs state you need a six-core system for six cameras, but some users (including myself) found that it's possible to get full res and speed from six cameras with an i7 quad-core if you're recording to a fast SSD. In my experience, the bottleneck is usually the connection between a storage device or the speed of the storage device itself. No guarantees of course but I think you'll be okay with what you're describing.

Hope that helps.

With your i7 + SSD + USB 3.0 card rig you should be able to capture from six cameras at 640x480 at 60 fps. By the way, slightly lower FPS (like 50 frames per second or 40 frames per second) should also be very usable for most times of motions.



Of course overclocking helps to achieve better compression performance. 20% higher clock should result in near 20% better compression performance.
