SpacedCowboy on Pre-sales questions regarding 4k NVR

Hi there,

So I was planning on buying the 8-channel 4k-ready NVR with POE (http://www.securitycameraking......-prd1.html) along with 4 of the 4k cameras (http://www.securitycameraking......-prd1.html) as well as one of the 12MP fisheye-lens camera (http://www.securitycameraking......EL12F.html)

Reading up on the specs, I had a few questions first:

1. I was planning on getting 2 of the Western Digital 6TB "Re" drives as storage - (WD6001FSYZ) unless the ones you supply are similar. Can you tell me the model number of the drives you'd supply if I were to go with 2x6TB from you ?
2. Reading the specs for the NVR, it seems it can only decode 1 4K video stream. Does this limit any alarm capability to just the one channel ? Or is the limit just for playback purposes ? Basically I want to set zones where motion-detect is important on all 5 cameras, and I want to make sure I'm buying the right NVR...
3. On the page for the 12MP fish-eye lens camera, it states that this "works best with the 64/128 channel NVR". What does this actually mean ? Can the 8-channel NVR work with the camera at all ? If there are any restrictions, what are they ?
4. There is no (4). There was a (4), but I forgot what it was

Cheers
