In order to increase a basic security of the installation for certain scenarios we have implemented an optional access authentication of the 2N® IP Mobile application to the in 2N® IP  IP Intercoms by an adjustable Access key. Thanks to the Access key on the side of the intercomsettings, only selected mobile applications with the equal key set in the 2N® Helios IP the Group Authentication field of the application can see detect the intercom connected in the same LANnetwork.
