Audio Settings

This section describes how to configure the basic audio settings for the network camera.

The audio functionality is enabled under Video & Au

dio > Video Stream > Audio.

Audio Channels

Audio mode - The Half duplex mode transmits and receives audio in both directions, but only in one direction at a time. To

speak, press and hold the button (check that the microphone is not muted). To receive audio, release the button.

Note:

The push-to-talk butt

on is configured from AMC (see AXIS Media Control (AMC), on page 12). It is possible to config-

ure the push-to-talk button so that it toggles between the speaking and listening modes.

With the S

implex - Network Camera speaker only option, the speaker connected to the camera plays audio, but no audio is

transmitted from the camera to other web clients. This could be used to provide spoken instructions to a person seen in the

camera. This mode requires you to use the push-to-talk button.

The Sim

plex - Network Camera microphone only mode transmits audio only from the network camera to web clients. It does

not receive audio from other web clients. This can be used in remote monitoring, and web attractions, to provide live audio

and video, of a monitored situation.

Audio Input

An external microphone or a line source can be connected to the Audio in the connector of the network camera. If an external

microphone or line source has been connected, the internal microphone will be automatically disconnected. The audio source

must be set to Microphone or Line depending on the connected device.

Note:

prevent unauthorized listening, the internal microphone can be disabled by inserting a plug in the Audio in connec-

tor.

The Enable mi

crophone power option provides DC power for an external microphone. If using a small electret condenser

microphone such as a clip-on microphone or a PC microphone, enable this option.

Note:

To use a high imped

ance dynamic microphone, do not enable DC power. DC power will not harm the microphone; if

you are uncertain, try switching it off and on. The default value is DC power enabled. To use a professional micro-

phone requiring 48V phantom power, you need an external power supply and a balanced-unbalanced converter (audio

transformer) in between.
