iOS Surveillance Calls
Surveillance Channel Group PTT calls mimic an LMR Radio behavior, with a dedicated channel that users can join and leave over time. Once started, the call will stay open until a configurable time period or until the last member has left the call. Based on configuration, the call can be idle for up to 2 hours before the call will be dropped.
|
Begin a surveillance call as you would any other group call or channel. Because users may leave and rejoin the call during the time that the channel is open, the in-call list will change accordingly.
Press TX on the Surveillance channel list and begin the call. |
|
The open call widget displays the call separately from the channel list.
|
| The closed call widget still displays information about the call and who has the floor. |
|
To configure your screen to darken during surveillance calls, go to your settings menu, turn on "Enable PTT Call Brightness" and adjust the slider for "PTT Call Brightness." |
