I have 2 of the NV6480EXP-16CH Cards setup running 32 cameras. My question is back when I got the cards they had a 32 cam version of the software and I could run all 32 cams at 640x480 at 30 FPS in turbo mode. I keep trying their newer software but they have removed the ability for the turbo mode in all new versions when using 32 cam. The max I can get is 15FPS. Why would they do that? I like alot of the newer features but I have to have as close to real time recordering as possilbe so for now I am stuck running the old version "NV6000E_V7.1.0.0047(32CH_Version)". And it does let me use turbo.
