GRAFFITI DETECTION SYSTEM AND METHOD OF USING THE SAME

摘要

The present invention involves a system and method for detecting a graffiti-making act (130) such as the spray of a spray paint can (140), the writing with a felt-marker pen on a surface (180), and the scratching with an abrasive instrument on a surface (180). The system (100) includes one or more sensors (110) adapted to sense the graffiti-making act (130) and transmit a signal (360) representative of the graffiti-making act (130), and a base unit (120) including electronics adapted to process the signal and determined whether the signal represents a graffiti-making act (130), and a communication device (340) coupled to the electronics (210) and adapted to communicate to one or more entities (150) that a graffiti-making act (130) has been detected. The method includes sonically detecting (335) the graffiti-making act (130), and initiating an alarm (280) indicating that the graffiti-making act took place.
