The 2N IP Mobile application in 2N Indoor Touch 1.0 and 2N Indoor Touch 2.0 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.
How to set the Access Key in the 2N Intercom
- Navigate to the section Calling (1), Local Calls (2), Configuration - Connection to answering units (3)
- Fill in the "Access Key" field, to enable authentication for the 2N Helios IP Mobile application.
- You can add up to 3 Access Keys as shown below:
