Push-to-talk (explained)

The push-to-talk feature enables you to communicate from a PC microphone through the VMS system with people near one camera or to start broadcasting audio to multiple video cameras with audio equipment. You can also listen to the recorded conversations in playback mode or include the two-way audio recordings in the audio package when preparing video exports.

XProtect Web Client supports the push-to-talk (PTT) feature:

• While you are watching live video from one camera or multiple cameras (see Viewing live video (explained)).
• When you play the recorded outgoing audio in video recordings (see Playing back audio in video recordings (explained)).
• In investigations and video exports.
• In actions (see Activate actions).
• In alarms (see View alarms).

You must allow your internet browser to have access to your PC microphones (see Requirements for using push-to-talk).

When the push-to-talk (PTT) feature is available for use, you will see the Push-to-talk button on the camera toolbar. Its icon has the following states:

Rules for interrupting push-to-talk in live mode

Based on the level of your user permissions (Administrators or Operators), there are two rules for interrupting a push-to-talk session in live mode:

• Users with the same level of user permissions cannot interrupt each other.
• Users with a lower level of user permissions (Operators) cannot interrupt users with a higher level of user permissions (Administrators).
