I am new here so bare with me. I am wiring a Dahua IP PTZ camera and it has many wires along with the Ethernet connector. My question is if the Ethernet w/PoE+ is used is it necessary to also hook up the alarm wires independently or is it included in the Ethernet connection. I know these cameras are backwards compatible with older coax systems with the use of adapters and that would require the use of separate alarm and audio wiring too. The generic Dahua install book is almost useless , basically covers all situations.
