A monitoring system (10) for monitoring the status of a facility (12) is disclosed. The monitoring system (10) comprises an alarm receiver (26) arranged to receive an alarm signal indicative of an alarm situation, to produce alarm data indicative of the alarm situation based on the alarm signal, and send the alarm data to a server (30). At least 2 communication paths (A, B) are used to pass the alarm data from the alarm receiver (26) to the server (30), and the system has a switching device (32) for selecting one of the communication paths (A, B) as an active communication path to use. The active communication path is selected depending on whether communications from the alarm receiver (26) are being received at the server (30). |
