The security door itself is a device that uses the magnetic field effect to detect metal objects. If a metal object is placed around it for a long time, uninterrupted false alarms will be triggered, which is not necessary for us. Then there is the life span and age of the equipment. When it exceeds the established working life, it will be scrapped. If there is a large magnetic object next to it, it will seriously affect the normal operation of the security door. It is recommended that you do not want to prevent large magnetic objects around.
