The BELEXPOCENTAR building has received a new metal detector door that will serve to increase the safety of its guests.
Metal-detector doors are intended for detection and prevention of bringing weapons into objects. When an armed person tries to pass, a visual and audible alarm is activated.
The first metal detectors, the forerunners of today’s modern ones, were made in America in the mid-1960s and were used in sawmills to detect nails in trees. Based on this device, door-shaped detectors are assembled.
The first places where doors were installed were airports.
