How to enable Two-way Audio on NVR

Note:

1. For NVR that does not support the Audio I/O interface, it only supports to talk with camera through Web page.

2. The Two-way Audio only supports one channel talking at one time.

3. Two-way Audio and Audio function can not be used together, including Audio of Playback, but if you are using Two-way Audio on one web page, you can use Audio on another page.

4. The audio interface of NVR can only be used alone. When other devices are talking to NVR, it would indicate that the device is busy if you enable Audio or Two-way Audio of other channels at the same time.
