The video link that you suggested is for an older Hardware NVR version. My NVR Hw# H3MB18 which means the video is not applicable. My UI screen is way different than the ones depicted in this video.

All cameras are connected directly into the RLN16-410. On the record clip, I do not hear the audio spoken from the phone app side. I still do hear audio input from the mic on the camera. I don't see where I set or adjust the noise reduction level.

Good Afternoon. I just installed my 16 channel Reolink NVR RLN16-410 (NVR661610104001000200000). I am having some audio problems. All my cameras (RLN811a, RLN823A, & Duo2) that have the 2 way audio capability are having the same issue. I can hear the audio from the camera but on the camera side the individual is unable to hear me. I am using the latest android app and the latest windows app downloaded from your website. The volume is set to max on all cameras under the tab "Audio and Light" in the NVR and on the app.
