SYSTEM AND METHOD FOR SURVEILLANCE

A system for surveillance according to an embodiment 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 first 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 signal analyser (121), wherein the air pressure signal analyser (121) is configured to receive an air pressure change signal indicating an air pressure change, or is configured to receive an air pressure signal indicating a current air pressure. The air pressure signal analyser (121) is configured to determine a second pattern matching result by determining whether the air pressure signal or the air pressure change signal comprises at least one pressure sensor pattern of one or more predefined pressure sensor patterns. Furthermore, the system comprises an evaluator (130), wherein the evaluator (130) is configured to indicate, depending on the first pattern matching result and depending second pattern matching result, that a predefined event occurred.
