Hey everyone, 
  
I have 4 families that live in close proximity in a high end condominium. Each of them want 2 cameras, making a total of an 8 camera system. 
  
Obviously each family's 2 cameras would be wired to their router but then how would I set-up a centralized storage option?  
I was thinking a Qnap NAS would be nice, is it possible to connect all 8 cameras to this system with 4 different networks? 
Or does each home need it's own NAS? 
  
Thanks guys!
