    Thanks a lot. I have also that tab, it is on second "page": I saw it already... This is first time I'm using RCA ports. I have also another model of mic so I will try it now. I will also update NVR firmware.

    Dahua NVR and external microphone

    Just tried it. There is no "More" button. Probably there is no one on planet Earth to explain two RCA connectors on this device then :)

    Dahua NVR and external microphone

    Dahua NVR and external microphone

    Hello, thanks for reply. You mean audio settings can be found using camera Web interface? I connected to camera IP address using Web browser, logged in but didn't find audio settings there.
