a first laser generation module configured to generate spot laser light through an LED that emits light in a set wavelength band;

a second laser generation module configured to generate spot laser light through an LED that emits light in a set wavelength band;

an optical module including a diffusion plate configured to diffuse the spot laser light, a main optical system configured to generate a rectangular projection image by combining lenticular lenses, each of which converts diffuse laser light into linear laser light, in a rectangular frame shape, and an auxiliary optical system configured to change laser light of the second laser generation module to an optical image of a set pattern, and to output the image within the field of view of the surveillance camera, the optical module outputting the projection image and the optical image of the set pattern in a filming direction of the surveillance camera;

a driving module including a motor and a driving system configured to adjust a distance between the first laser generation module and the optical module and adjust a size of the projection image by driving the motor;

a control module configured to control the first laser generation module and the motor in response to an angle of view of the surveillance camera, and to make the field of view of the surveillance camera coincide with a location and a size of the projection image; and

a facility monitoring module including an information management unit in which facility information including a type and standard of a facility to be monitored is stored, an analysis unit configured to analyze an image of the surveillance camera to identify a moving object and to track a location and a movement path in real time, a determination unit configured to calculate a size of the moving object and to generate collision prediction information based on the facility information and the movement path, and an alarm unit configured to reflect a determination result of the determination unit and to output an optical image of a pattern set through the auxiliary optical system to an outside of a facility.
