I have a MARS NVR Combo Kit, product Model Number: MR-4040I 
I must replacing rj45 female connector of one ipcamera (water inflitration).  
  
I bought a rj45 female connector, but when I cut the wire, I discovered that it has 10 wires! 
Probably the black and red wire go merged with other colors, right? 
  
I attach photo. 
Help me, please.
