I have a 32 camera DVR setup with 16 Channel audio and I'm having some serious issues getting the microphone's working. I have tested with both in line microphones, and I have camera's with built in microphones and no matter what I try I get a serious static/buzzing issue. I was originally thinking I had a ground issue but I've tested that the best I can and ruled it out. The furthest wire I'm running is 100 ft. I originally used 3 way Power/Audio/Video CCTV wire and to try debugging it I went with separate audio wire for just the microphones. If you have any ideas on anything I can test or would like to see the issue I can answer any questions you'd like or give you a guest account to the DVR. I've done multiple CCTV camera installs, although this one is the first with audio. I've been on google for hours and can't seem to find anything remotely regarding the issue I'm facing that has a solution.
