PURPOSE: A pseudo alarm system for blocking effectively an invader is provided to reduce largely the manufacturing cost by using a CCD camera unit without photographing function and recording function. CONSTITUTION: A pseudo alarm system for blocking effectively an invader includes a CCD camera unit and a pseudo alarm generator. The CCD camera unit includes a sensor for sensing an approaching state of the invader and a pseudo CCD camera for performing a regularly shifting operation without performing a photographing function and a recording function. The pseudo alarm generator(10) is connected to the CCD camera unit in order to generate the pseudo alarm sound.
