    Can Dahua NVR mic in supply audio for all the cams connected to said NVR? I tried to set this up through the web GUI but I could not find any option to enable this.

    Can someone help me with this? If this is not what the mic input on the NVR is for then is it basically just used in conjunction with mic out for two way communication?

    I believe the MIC IN on the NVR is for an external mic, not one that is in a camera. Mic's that are in the camera supply their audio to the NVR over the Ethernet connection.

    Looks like I found my answer here Enabling Mic Connected to Audio In of NVR

    "So what is the Audio in - out connection for at the back of the NVR?"
    "Bi directional audio. You can "speak" from the NVR to any camera that has speaker or audio output."
