Hi guys.
I want to connect a microphone to the audio in of a SD5A425XA-HNR cam. The cam then should record the combined video/audio to a dahua NVR. The mic is wireless and the mic receiver has only an XLR output. How do I wire the XLR to the audio in of the cam?
Thank you.

PS. From the mic receiver manual:
This is a standard XLR configuration with pin 2 “positive” with reference to hand-held and plug-on transmitters. With lavaliere microphones and belt-pack transmitters, however, phase will vary with different types of microphones (2-wire vs. 3-wire for example). The audio output is balanced but not floating, so an unbalanced signal is available using pin 1 as ground and pin 2 as signal, leaving pin 3 open.

I haven't done this but I did locate 2 sources that say to tie XLR pins 1 & 3 together and run to sleeve of RCA; run XLR pin 2 to tip of RCA.
