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