Part 2 - Configuration

Audio

Configure audio recording settings for all cameras
simultaneously.
● Audio Codec: Select an audio codec. (G.711 u-Law,
G.711 a-Law, ADPCM 16KHz or G.726)
● Associated Audio In: Associates the selected audio
channel with the camera. It is supported by video
encoders only.
● Audio In: Select an audio input source (microphone
or line-in) and then adjust the volume. Auto detection
function detects the audio input and automatically
selects the audio-in device. Noise Filter reduces the
environmental noise and enhances the voice. If you
turn on the noise filter, the sound may be distorted
somewhat. We recommend that you do not use this
function in a loud place because it may degrade
performance.
● Audio Out: Adjust the volume.
Cameras do not feature built-in audio amplifier units
and therefore require the user to purchase a speaker
system with a built-in amplifier separately.
