First let me preface this by saying im thoroughly impressed by the knowledge of this forum, and by the Dahua cameras and NVR I recently received from Andy. Unfortunately, I trashed the female connector on my 5231 while trying to hurry and install it before a storm. Undeterred, I sought to repair it tonight. I read and discovered the Dahua wiring is not the same as your typical ethernet color codes... I have little wiring experience - I just punched down my first patch panel, keystones, and RJ45s last week. I cut off the damaged connector and discovered there are 6 wires (see attached picture). Using a multimeter, I traced it to the following pinout: (see attached picture). Based on the reading ive done on PoE, this SEEMS to be traced correctly. Now I have the next problem to solve: this small gauge stranded wire wont punch down in my keystones, and im not sure how (if even possible) to crimp an RJ45 when I have 6 wires. Once I figure out how to put a connector on this camera, ill report back and advise if it works.
