Axis Q1755 User Manual page 10

How you customize the Live View page determines which buttons are visible. Not all the buttons described below will show
up, unless configured to do so.
When using the Half-duplex mode, this button toggles, allowing you to speak and listen. The first icon indicates that you
can talk and the speaker attached to the camera will play your voice. The second indicates that you will hear audio from
the camera, but no audio is sent to any web client.
When in Simplex talk mode, the icon toggles allowing you to speak, and is dimmed when you do not want other clients
to receive any audio.
Use the slider to control the volume on the speaker and microphone.
