A LONG RANGE PORTABLE SECURITY DEVICE THAT BROADCASTS ALERTS UPON DETECTING INTRUSION EARLY BY MONITORING VIBRATION

摘要

A low power portable vibration detector and a method for alerting a user or authorities irrespective of their proximity is disclosed. The device comprises of a circuit board, an antenna and a power source all enclosed in a housing. Upon sensing a vibration that e xceeds a predetermined amount, a voltage change triggers a processing unit that in turn triggers an alarm and/or broadcasts an alert via close range, long range wireless networks, and/or the internet and/or via telephonic land lines. The device generates alerts when a n attempt is made to disable or tamper with its functionality as well. Thus the system described employs a vibration detector and its associated hardware to accomplish the task of serving as a very reliable early intrusion detection system.
