Walk-through metal detectors are installed at the entrances to facilities to detect weapons and metals that individuals may be carrying as they pass through. They are equipped with a large number of sensors to detect prohibited items that may pose a threat to the facility and are widely used in hotels, airports, large malls, banks, and companies, They are also used at celebrations, events, stadiums, and sports arenas frequented by large crowds to prevent the entry of weapons that endanger public safety.
When people carrying weapons or metal objects pass through, the sensors detect them and sound an alarm to alert the security guard, who then searches the person and takes appropriate action.
