Congure audio recording settings for all cameras
simultaneously.
● Associated Audio In: Associates the selected audio
channel with the camera. It is supported by video
encoders only.

G.711 a-Law, ADPCM 16KHz or G.726)

– Device: Select an audio input source (microphone,
line-in or HDMI) and then adjust the volume.
– Auto detection: Detects the audio input and
automatically selects the audio-in device.
– Volume Control: Adjust the volume manually or
automatically. Select the Auto option to adjust
the volume automatically depending on the

– Volume: Adjust the volume manually by using the

– Noise Filter: reduces the environmental noise
and enhances the voice. If you turn on the noise
lter, 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 amplier units
and therefore require the user to purchase a speaker
system with a built-in amplier separately.
