I'm considering a Dahua NVR5232. I don't need 32 channels but it sounds like I have to if I don't want to max out the box with a few high res cams. Could someone please explain why that is? I thought the limitation was the max recording bandwidth. The 8/16/32 all have the same specs. Realistically I'll run 3-4 5mp cams and hopefully another 5-7 2mp cams at 10+fps. Is this the box for me? Also I was wondering if I should go with the -8P version. I hear the fan is a lot louder and the ports tend to fail. I don't mind buying one more poe switch.

Currently I have two P4 computers running 16 analog coax cameras each on standard PCI cards. The problem is the quality is very low. I assume the standard PCI DVR cards are the problem. When all but one camera is disabled frame rate increases but quality remains poor. I know the cameras are good partly because they were expensive but also because when hooked directly to a monitor quality is very good. 1. What cards are available in PCI-e x4 or better? 2. What kind of quality gain can I expect over standard PCI? Is it just too much to ask for decent quality when using 16 cameras per card? 3. Can two cards be used in one server with multiple PCI-e buses? Is there software that can support 32 cameras? Any info or other solution ideas are greatly appreciated!
