If you want to communicate with the participants in the observation room, you need a push-to-talk license and a pair of speakers in your participant room.
Speaker attached to Camera
To enable the PTT functionality, if your setup contains a pair of regular active speakers, works like this:
▪Attach a speaker to the audio-out socket of one of the cameras.
▪Select the Source that represents that camera with the speakers attached in the Audio /Video Source list.
▪Select Activated behind the Push to Talk option of that source.
The moment you use a source with PTT activated, within your current Scenario, an additional button appears at the bottom of your VideoSyncPro window:
Axis Network Speaker
If your setup contains an Axis network speaker (C1004-E, ), setting up PTT works like this:
▪Attach the Axis Speaker to a PoE port of the Mangold VideoLab network switch.
Configure the speaker like any other Axis network device:
▪Open the Axis IP Utility.
▪Double-click the entry of your speaker to get to the web-based backend of the device.
During a first-time setup of a new device:
▪Enter 'Mangold' as your (new) root password
or
▪use it to log in to the configuration.

Now you can specify your new source:
▪Enter an appropriate name for that source into the field Source name, for instance, ‘Camera 1’, 'Audio Encoder Room 1', or 'PTT Speaker', depending on device type and location.
NOTE: For video sources, this source name also determines the file name for its recorded videos.
▪Enter the IP number that matches the corresponding device, as listed in the Axis IP Utility window, into the field IP address.
▪Click Verify source to automatically identify the Device type and check availability,.
A dialog appears, informing you about the availability of the source and the detected device type. If applicable, a notification about corrected device information appears as well.
The correct device type, as listed in the IP Utility window, is now automatically selected in the Device drop-down list.
