Good day all !!  New member here. 
  
I looking for a NVR with at least 4TB and wired gigabit RG45 connection.  Since I have all  Mac OS and IOS computers and devices it seems it has to have a web interface so I can interface from my iMac.  I have 8 Vivotek HD IP cameras, one is a 2MP and the rest are 1MP (3 Wireless and 5 POE).  I also have a portable Cisco IP PTZ  and Foscam IP PTZ indoor camera that I use occasionally.   
  
I have tested that the network and it can support all 9 cameras saving to a NAS server with very little effect on bandwidth, but have failed in finding a solution that is MAC OS based that can do cyclic storage and disk cleanup on the NAS.  I really want a stand alone NVR solution that doesn't run on one of Mac computers.  It would be housed in our comm closet in the attic. 
  
Any thoughts would be greatly appreciated. 
  
Thanks,
