Disclosed is a hub station of an alarm system, having: a hub station housing; a hub station controller disposed within the hub station housing, wherein the hub station is configured for: communicating, bi-directionally over a short range network during an active alarm condition, with a plurality of client stations that are distributed in a plurality of zones, the plurality of client stations each including a housing and located therein a power transformer, a speaker, a microphone, and one of a plurality of controllers; obtaining, from the communicating during the active alarm condition, intrusion sound data indicative of sounds received by one or more of the plurality of client stations; and determining, from the intrusion sound data, intrusion location data indicative of a location and movement of an intrusion among the architectural zones; and forwarding, over a long range telecommunications network, the intrusion location data to a central station.

The disclosure relates to a system and method for providing enhanced security of physical assets within a physical infrastructure. The method includes receiving an overall layout of the physical infrastructure and multi-modal input with respect to the physical asset from a plurality of sensors installed within the physical infrastructure. The multi-modal input includes acoustic signal generated by or reflected off the physical asset and captured by a set of acoustic sensors. The method further includes generating a digital asset corresponding to the physical asset by determining an identification, a location, a shape, a size, and a behavior of the physical asset based on the multi-modal input and the overall layout, detecting one or more events of interest involving the digital asset based on the behavior of the physical asset, and simulating the one or more events of interest to evaluate a possible fault or a possible security threat.

Disclosed is a hub station of an alarm system, having: a hub station housing; a hub station controller disposed within the hub station housing, wherein the hub station is configured for: monitoring, over a short range telecommunications network, a plurality of client stations that are distributed in a plurality of architectural zones, the plurality of client stations each including a client station housing and located therein a client station power transformer, a client station speaker, a client station microphone, and one of a plurality of client station controllers; determining, from the monitoring, that an alert condition exists in the one of the architectural zones; and establishing a first bidirectional communication concurrently with two or more of the plurality of client stations distributed in the plurality of architectural zones.

In accordance with an embodiment, a system for surveillance includes an audio signal analyzer, wherein the audio signal analyzer is configured to receive one or more audio microphone signals, where the audio signal analyzer 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; an air pressure change determiner, where the air pressure change determiner is configured to receive an air pressure change signal indicating an air pressure change; and an evaluator, wherein the evaluator is configured to indicate, depending on the pattern matching result and depending on the air pressure change, that a predefined event occurred.

In accordance with an embodiment, a system includes an audio signal analyzer configured to receive one or more audio microphone signals, and configured to determine a first pattern matching result by determining whether the one or more microphone signals include at least one audio pattern of one or more predefined audio patterns. Moreover, the system includes an air pressure signal analyzer configured to receive an air pressure change signal indicating an air pressure change, or configured to receive an air pressure signal indicating a current air pressure. The air pressure signal analyzer is configured to determine a second pattern matching result by determining whether the air pressure signal or the air pressure change signal includes at least one pressure sensor pattern. Furthermore, the system comprises an evaluator configured to indicate, depending on the first pattern matching result and depending second pattern matching result that a predefined event occurred.
