There are 2 audio codecs, G.711 a-law and G.711 µ-law, that can be selected for audio input encoding.
Level: High/Mid/Low
Three audio levels, Low/Mid/High, are selectable for audio input and output individually.
Note
The audio output performance is not influenced by the codec combination.
The camera only supports one user to use audio out. Once the audio out is in use,
others cannot use this function on live view.
The encoding of audio output is determined by the transmitter (NVR or ActiveX)
rather than the camera; the current supported formats are G.711a-law and
G.711u-law.
