The 2N® IP Mobile application in 2N® Indoor Touch can communicate with all 2N IP Intercoms in the local network (and vice versa) by default. In order to increase basic security of the installation for certain scenarios we have implemented an optional access authentication for the 2N® IP Mobile application in 2N IP Intercoms by an adjustable Access Key. Thanks to the Access key settings, only selected mobile applications with the key set in the Group Authentication field of the application can detect the intercom connected in the same network.
It is strongly recommended to use the latest FW version on 2N IP Intercoms - available here or via the automatic update feature.
The Group Authentication/Access key feature does not require any additional license for the 2N IP Intercom.
