Someone asked for very detailed instructions a while back, so I made sure to take pictures the next time I had a chance. Equipment: Powered Microphone with power passthrough Male to Male RCA Coupler 12v PoE Splitter Requires: PoE Camera with 12v Barrel Plug & RCA Audio Input Junction Box mounting with enough room for it all. No Legal Restrictions on Audio Recording. See attached photos for wiring.. basically.. PoE Splitter to Mic Power IN, Mic Power Out to camera, Mic Audio out to Camera, and finally Poe Splitter RJ45 to camera.. The RCA Coupler connects the two female outputs of your camera and microphone together, you can see it in the photos. I'll get pix of my other camera that did not take a RCA input, it took a mono 3.5mm input.. so I hacked the rca plug off and splice it in with the right connector..
