indicates if they are enabled.
You can add a new mask, re-size the mask with the mouse, choose a color for the mask, and give the mask a name.

Audio Modes
The Axis product supports the following audio modes:
• Full duplex – Simultaneous two-way audio allowing the Axis product to transmit and receive audio at the same time.
There is no echo cancellation; if feedback loops appear, try moving the microphone or the speaker.
• Half-duplex – Audio can be transmitted to and from the Axis product but only in one direction at a time. To transmit
audio using the Live View page, use the Talk and Listen buttons, see AMC Audio Controls on page 12.
• Simplex – Network Camera speaker only - Audio is transmitted from a client to the Axis product and can be played by
a speaker connected to the product. To transmit audio using the Live View page, the Talk and Microphone on buttons
must both be active, see AMC Audio Controls on page 12.
• Simplex – Network Camera microphone only - Audio captured by the product microphone is transmitted from the
Axis product to one or more clients.
To set the audio mode, go to Video & Audio > Audio Settings and select the desired mode from the Audio mode drop-down list.
Audio Input
Note
If using unbalanced Line in a mono contact must be used. Signal on tip and ground on sleeve.
Select Microphone to use an external microphone or Line to use a Line in device, e.g. an audio mixer for multiple microphones
or a microphone with a built-in amplifier, as audio source.
Select the +30 dB microphone boost option to amplify the signal of the external microphone connected to the Axis product.
Microphone boost option is useful when a microphone's volume is too low and you want to increase it. This option is not available
when the Line source is selected
Select the microphone sensitivity level (High/Low) depending on the sound level in the monitored area. For example, if the Axis
product is installed in a noisy environment, try setting the input sensitivity to Low.
The Microphone power option provides DC power for an external microphone.
To use a professional microphone requiring 48V phantom power, you need an external power supply and a balanced-unbalanced
converter (audio transformer) in between.
