| Zusammenfassung: | Apparatus for detecting a signal indicative of presence at least one of an air flow or an optical fibre at a remote location, comprising
- an air vibration detector (30) configured to acoustically couple with a fibre tube through which the signal can travel after its generation at the remote location, and
- a processor (24) arranged to receive an input from the vibration detector and to process the input to identify the signal present within the input. |
