    I have traced the pinouts on both a HFW2100 and HFW3200 I do not know if Dahua always wires their cameras this way but here is what I have found. (see diagram) The Ethernet cable follows the 'A' standard not 'B'

     

    Pins 4&5 are tied together internally as are pins 7&8. I cannot vouch for about the actual wire functions (ie, Video, etc.. Accept the POE lines are pretty clear. Note that 4&5 are POE+ while 7&8 are POE- This is different than the diagrams shown above. I also found that there are four wires going to the +12v power jack I assume they double up to handle the larger currents.

     

    I have rebuilt the connectors on both cameras using this and they function ok

     

    I hope this helps.
