I have an existing camera system in my office, decided I would like audio (Texas 1 party consent state), to record audio and video of client interactions. I ran the provided cable (100ft) to the camera and mounted the mic pickup alongside the camera and plugged the audio plug into my existing DVR and the power cable uses the same multi power plugs as all my other cameras so I have multiple unused power plugs. That was it, I was able to hear very clearly in sync with the camera. Very easy to install no real configuration was involved with the MIC other than mounting it and running the cable back to the DVR. Good quality product.
