Audio Playback
In playback mode, click or on the channel status bar to play or mute audio.
Note: To make a video backup with audio, make sure the camera which supports the audio function is
connected to the video-in channel and audio-in channel. For example, the audio data from audio channel 1 will
be recorded with the video data from video channel 1. For 8-channel models, audio channels 1–4 correspond to
video channels 1–4.
