Can I Use Two-Way Audio on NVR

Applies to: All the cameras that support 2-way audio (except battery-powered cameras)

For the newer NVR (H3MB18/N2MB02/N3MB01), if you upgrade the firmware for the NVR to the latest version, it can support the 2-way audio function via Reolink Client/App when the cameras are connected.

But this function is not supported when the cameras are connected to the NVR with the Hw: H3MB02/H3MB16)
