SYSTEM AND METHOD FOR SURVEILLANCE

A system for surveillance is provided. The system comprises an audio signal analyser (110), wherein the audio signal analyser (110) is configured to receive one or more audio microphone signals, wherein the audio signal analyser (110) is configured to determine a pattern matching result by determining whether the one or more microphone signals comprise at least one audio pattern of one or more predefined audio patterns. Moreover, the system comprises an air pressure change determiner (120), wherein the air pressure change determiner (120) is configured to receive an air pressure change signal indicating an air pressure change; or wherein the air pressure change determiner (120) is configured to receive an air pressure signal indicating a current air pressure and is configured to determine the air pressure change from the signal indicating the current air pressure and from a previously received air pressure. Furthermore, the system comprises an evaluator (130), wherein the evaluator (130) is configured to indicate, depending on the pattern matching result and depending on the air pressure change, that a predefined event occurred.
