For the management of certain high-level security areas, security doors or identification devices are generally installed at the entrance of the security areas, so that when the authorized personnel of the co-management is present, after each card is swiped, password is entered or identity is identified, it is believed that the authentication has entered the confidential area. However, this kind of access has some defects: It is impossible to determine whether the authorized manager has actually entered the control area after the authentication; There is no technical assurance that some managers have allowed unauthorized personnel to enter on their behalf; there is no technical assurance that unauthorized personnel have followed them. Due to the shortcomings of the above-mentioned methods, they can not meet the current management requirements for the entry of various high-level secret areas. To this end, our Joint National Nuclear Security Technology Centre has successfully developed the“In-and-out”method, it can control the access of authorized personnel in the high-level secret area, verify the number and identity of authorized personnel, and ensure the security of the controlled area.
As a safe and reliable equipment to enter the high-level security area, the door of going in with going out together has successfully solved the problems in this field at home and abroad, and has been granted a national invention patent. After Beijing Samsec security gate with the same in and out of the material audit, our company won the new technology new products (services) certificate.
