I have multiple DAHUA cams connected to 1 DAHUA NVR and I have trouble with 2 way audio.
I connect the NVR from SmartPSS or Web interface on my local lan
I select the camera in live preview
I click the "SPEAKER" icon and I have the sound from the mic of the camera ->OK
Then I click the "MIC" icon , the camera speaker should broadcast the sound from my PC/laptop microphe but it doesn't -> No sound output
Even more strange I get on my PC speaker the sound from NVR connected microphone
I'm getting crazy with this.
Any idea would be welcome
