US 10,319,201 B2 · Systems and methods for hierarchical acoustic detection of security threats

Abstract

Systems and methods for detecting a security threat over a network are provided. The system comprises a microphone configured to capture acoustic signals; a hardware interface configured to generate data samples from the acoustic signals; a memory storing a plurality of instructions; and a hardware processor configured to execute the instructions to: determine information indicative of a rate of intensity variation of the acoustic signals; and determine, based on the information, whether to transmit the data samples to a remote server. The hardware processor is also configured to, after determining to transmit the data samples to the remote server, generate data packets that include the data samples, and transmit the data packets to the remote server. The remote server can then reconstruct the data samples from the data packets and, if the data samples indicates a security threat, transmit a warning signal to a monitoring device.
