- Abstract
- Provided is a security surveillance system and method capable of separately detecting fire and intrusion situations on the basis of a sound field variation, including a sound generating device outputting, into a set security surveillance space, a multi-tone sound wave formed of a linear sum of sine waves having a plurality of frequency components, a sound receiving device obtaining sound field information for each frequency represented as sound pressure and a phase from a sound wave received in the security surveillance space, and a sound field signal processing device storing sound field information for each frequency obtained from the sound receiving device in a preparation mode, comparing the stored sound field information with current sound field information for each frequency output from the sound receiving device in a surveillance mode, and determining occurrence of a security situation.
