Push-to-talk (explained)
The feature enables you to communicate through the XProtect VMS from the microphone of your mobile device with people near a video camera with audio equipment. You can also listen to the recorded conversations in playback mode.
XProtect Mobile client supports the push-to-talk (PTT) feature:
- While you are watching live video from one camera (see Viewing live video).
- When you play the recorded outgoing audio in video recordings (see Find and view video recordings).
- In investigations (see View or create an investigation).
- In alarms (see View alarms).
- In access control (see View doors and take action, Investigate access control events and Respond to access requests).
You must allow the XProtect Mobile app to have access to the microphone of your mobile device (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:
| Icon | Description |

In live mode, it shows that the push-to-talk (PTT) feature is available and that you fulfilled the necessary requirements for using it. Tap and hold to start using push-to-talk. Release the button to end transmitting audio. |

(iOS)Rules for interrupting push-to-talk
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).
