Abstract
A network audio-link alarm monitoring system for sensing the sound from triggered alarms and reporting the arm to alarm authorities. The system and method of the invention relies on the aural sound produced from alarms that have been triggered. The system, implemented on a PC or other processor on premises, differentiates the sound coming from different alarms, characterizes the sound as from a particular alarm via FFT processing and reports the alarm over the Internet, public switched telephone, or other communication link to a central station which then reports the alarm to the alarm authority. In another embodiment, the reporting of the alarm is done directly by the PC at the residence or business to the alarm authority over the Internet or other communication link.
