Other valuable functions of IPervoice included:
Lift control – An added layer of resident security with Resident Lift Control for the penthouses. When entering the building, residents simply present their proximity token to any reader. This then calls the lift to the ground floor and automatically takes residents to their own floor. A similar function, operated via a remote lock release button on the video monitor in their apartment, also allows residents to send the lift to the ground floor when someone calls them. The Visitor Lift Control then only allows the visitor to select the floor they are visiting, which means they are prevented from entering the rest of the building.
