Adding a Microphone directly to the DS-7732NI-M4-24P NVR?

[imtiyazp]

I have a DS-7732NI-M4-24P - POE Network Video Recorder with 16 cameras connected to it. 4 of the cameras have a mic and speaker built-in for 2 way communication via the HikConnect app. It all works very well.

However, since I have a monitor in my office with the cameras always displayed, I would like the option to use a microphone in the office to talk to any of the 4 cameras I have selected without using the phone app.
If I was to connect a microphone to the Audio-in port at the back of the NVR. I am assuming I can do this?
Or, would the microphone simply act as a disjoint recording channel just for audio and not link live to any camera?
