There's a microphone input (Mic-In) on the NV4108E-HS and you can listen to it in the app. Is there a way to record it to one of the channels?
I have an IP camera with built-in microphone and I can record the audio, and I have one camera without microphone. I'd like to record this local microphone input to that camera channel.
In all amcrest DVRs I had before there was an option to record local microphone to the channel 1, but I don't see this option on NV4108E-HS NVR.
