Video and Audio

Privacy Mask

A privacy mask is a user-defined area that prevent users from viewing parts of the monitored area. Privacy masks appear as blocks of solid color and are applied on the video stream. Privacy masks cannot be bypassed using the VAPIX® application programming interface (API).

The Privacy Mask List (Video & Audio > Privacy Mask) shows all the masks that are currently configured in the Axis product and 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.

For more information, see the online help

Important

Adding many privacy masks may affect the product’s performance.

Set Up Audio

To change the product’s audio settings, go to Video & Audio > Audio Settings.

Each stream profile is a separate video stream. To include the audio stream in all stream profiles, go to the audio tab in each stream profile settings page and enable audio. For more information, see Stream Profiles on page 20.

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 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

An external microphone or a line source can be connected to the Audio-in connector. Configure the audio input settings under Video & Audio > Audio Settings.

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 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. Microphone power should only be used with microphones that have no battery. This setting should not be enabled when using a dynamic or battery powered microphone.

To use a professional microphone requiring 48 V phantom power, you need an external power supply and a balanced-unbalanced converter (audio transformer) in between.
