Smart Home Security Module based on Sound Field Security Sensor


Technology Summary

  • New sensor technology that detects and classifies security events such as fire and intrusion even in blind spots based on sound transfer function variation using a speaker and microphone set in secured spaces such as home and car
    • The smart home security system is composed of smart CCTV, gateway and security control system, and the smart CCTV is composed of an IP camera with a sound field security sensor.
    • The smart home security system is able to detect the early stage of fire or an intruder even in blind spot using a new sound field security sensor and to send alarm message to a smartphone in order to get “golden time” for the fast reaction in fire emergency situation, and to overcome the weak points of conventional intrusion detection sensors such as difficulty in dark or blind spot and error alarm.
