Hi, Josephine regarding your LV-KNT0404D1, first, you need to have RG59 pre-made cable and microphone, connect microphone to RG59 cable and camera both power port. another RG59 Pre-made cable for audio, use a BNC-RCA converter connect to the audio cable of microphone, another side of the audio cable connects to the AUDIO IN by using another BNC-RCA converter. and then go to your NVR, go to menu, record, on main stream setting, second from the last, it should be said "audio record" and check that box, so then your NVR will able to do audio record. I hope this would helps you out. Steveiscool !!
