PURPOSE: A method and apparatus for continuous sensing of human body is provided to prevent theft by continuously sensing the human body when the human body moves or stops within the sensing range. CONSTITUTION: A human body sensor(14) is fixed to a boss(8) of a fixing bracket(7), and the fixing bracket is fixed to a board(1) through a screw(9). A rotor(10) having a slave gear(11) is fitted in a rotatable manner to the boss, and a lens(12) having a prism surface(13) is fixed to the rotor. A deceleration motor(2) is fixed to the board through a screw(4), and a prime gear(5) having a support disk(6) is fixed to a shaft(3) of the deceleration motor. Thus, the prime gear and the slave gear are engaged with each other, and the support disk supports the lower portion of the slave gear. The human body sensor is maintained at the fixed state, while the lens having the prism surface is rotated, to thereby refract the energy value which is emitted from the human body moving or stopped and incident to the human body sensor.
