An object of the present invention is to realize a camera system suitable for remote monitoring. The method includes the step of providing a sheet containing reinforcing fiber yarns over the surface of a structure selected from the group consisting of concrete and steel structures, with a flexible material interposed therebetween, the flexible material having a tensile elongation of 10 to 200% at maximum load at 23\xb0 C. The safety device is mounted in the cabinet body and has a control member and multiple hook members. The micropores have inlet diameters smaller than bottom diameters thereof. The control signals control a \u201crecognized persona\u201d or avatar stored in a memory to provide simulated human attributes to the apparatus, network or third party communication device. A positioning device may be positioned about the second column to maneuver the second products to the heating device and the dispensing path so as to dispense the second products as heated.
