The access control system Metalo Lobby Phone manages the authorised access to a building. The five authentication methods meet high safety standards: facial recognition, fingerprint recognition, passwords, RFID cards and visitor calls. The main functions can be controlled via smartphone, allowing users to control access also from a remote location. The design’s straight lines in conjunction with select materials such as stainless steel, aluminium and tempered glass have been developed to harmonise with modern building facades.
