The GV-2008 is an 8 channel video capture card with on-board MPEG4/MPEG2 hardware compression. Total recording rate is 240 fps at 720x480 resolution. This is a great surveillance solution if you also want to use your computer for other tasks. CPU loading and memory usage are minimal due to the hardware compression.
I just upgraded my PC to 64-bit Windows 7, which is not compatible with this card. It's in perfect working order. I can also supply Geovision V8.2 software if needed. Asking $450.
