SECURITY SYSTEM AND SECURITY METHOD

摘要

PURPOSE: A security system and a security method are provided to adjust a tilting angle of a camera and trace and photograph a moving subject without installing a plurality of cameras. CONSTITUTION: A security system includes a sound source sensor(110), a sound source tracer(120), a photographing unit(130), and a controller(140). The sound source tracer grasps a location of a traced object which generates sound using a sound volume difference and a time difference to generate location information of the traced object. The photographing unit generates a preview image about a partial area of a target space. The photographing unit stores a plurality of tracing images by photographing the traced object. The controller adjusts a tilting angle of the photographing unit to photograph a traced object. The controller outputs a photographing signal to the photographing unit if adjustment of the tilting angle is completed.
