Thanks Toss for taking the time to get back to me! Not quite sure I understand your response though...
FYI, I pasted the system specs directly from the Dahua website. So if they don't make any sense to you, then they would definitely not to a newbie like me...maybe I'm barking up the wrong tree
Given what I pasted initially and below again, I'm trying to figure out if one system can handle a higher recording rate running the same amount of cameras (whatever the camera setting is on each, 2MP, 1.3MP etc.) I merely stated 8 cameras @ 2MP to assist with someone doing the math (if that math is possible given what Dahua supplied)
Here's the links to the system specs:
System 1 Dahua NVR 58xx: "record rate: Max 128Mbps ( eg. 16ch 5MP@8Mbps, 32ch 1080P@4Mbps & etc.)"
System 2 Dahua NVR 38xx: "record rate: 400/480fps@D1, 200/240fps@720P , 100/120fps@1080P"
