Hi, 
  
I am thinking about purchasing a camera system from Hikvision for my business and came up with this: 
  
DS-2CD2512F-IS = 4 Cameras @2.8mm 
DS-2CD2032-I = 6 Cameras @4mm 
DS-2CD2032-I = 6 Cameras @6mm 
DS-7716NI-SP, 16CH NVR = 1 NVR 
  
I have a few questions and I figured why not pitch it to the pros before trying it out: 
1.) All the cameras are PoE, but my business is 72m L x 55m W (3960m^2) and some of the cameras will have to go beyond the 100M limit. Should I get repeaters for this or would it be fine without? 
2.) What cable should I use, I was looking at the Cat 6 FTP cable but I'm not 100% sure as yet. Also should I get Solid or Stranded? 
3.) I have been reading on several forums that in terms of hardware ONLY, the English-Chinese Hacked Cameras + English-Chinese Hacked NVRs are the exact same as the Hikvision USA cameras and NVRs. If this is true then how would I go about changing the firmware of these specific cameras and NVR to that of their English counterparts? 
4.) Also are the English-Chinese Hacked Cameras compatible with an English NVR? (All of this is from Hikvision). 
  
I apologize if this has been posted before, but this has been bugging me for the passed 2 weeks and I have no idea what to do, whether I should get them or not. 
  
Looking forward to your reply.
