It's interesting to note that Dahua has changed all of their NVR6000 web site specs/PDFs The old spec was 128ch@d1, 64ch@720, 32ch@1080 (all at real time 30fps) The new spec is 128ch@720, 64ch@1080 (still at real time 30fps) Their 64ch NVR6064 had a similar increase from 16ch@1080 to 32ch@1080, 64ch@720. Also it looks like their newer model NVRs have a published maximum recording bitrate of 128MB/sec, and the system doesn't care how you reach it. Qty 32 Axis Onvif 5MP cameras @ 4MBps CBR would be within the spec of their 32ch series.
