In this case, events and alarms are transmitted simultaneously via two channels: via the internet and via vhfBridge.
Transmission via the internet works as the main communication channel due to its greater reliability and information capacity. The transmitted events can contain the zone number of the triggered detector, group, user, and other data.
vhfBridge works as a backup communication channel, duplicating all events transmitted via the internet.
The delivery speed of events and alarms in both cases does not exceed 1 second.
