Abstract
A security device includes an impact sensing unit for sensing an impact, a sound pressure sensing unit for sensing a sound pressure, an abnormal degree determination unit for determining an abnormal degree based on a level of an impact sensing signal sensed by the impact sensing unit and a level of a sound pressure sensing signal sensed by the sound pressure sensing unit, and an alerting process unit for performing a predetermined alerting process based on a determination result of the abnormal degree by the abnormal degree determination unit.
