If you use 2N® Indoor Touch as an answering unit for 2N® 2N IP Intercom in the local network, the video stream from the 2N® 2N IP Intercom can be received over the unicast of multicast communication. This guide briefly summarizes when and how to use one of these options, however for a detailed explanation see please the corresponding FAQ with the complete Network requirements.

There are two ways how the video stream from the 2N® 2N IP Intercoms can be received by the 2N® Indoor Touch in the local network:

  1. Unicast (suitable for up to 3pcs of 2N® Indoor Touch)
     easy to setup - factory default value, works smoothly over Wi-Fi, no need for smart active network parts (eg. managed switch, advanced Wi-Fi access point etc.)
     limitation of up to 3 devices to simultaneously watch the stream from the 2N® 2N IP Intercom, no audio listen in (audio preview)

  2. Multicast (suitable for 3+pcs of 2N® Indoor Touch)
     unlimited devices to watch the video stream from 2N® 2N IP intercomIntercom, audio listen in (audio preview), optimised network bandwidth usage
     smart active network parts with multicast support required (especially for Wi-Fi)


For further details how to set the 2N® Indoor Touch and 2N® IP Intercom see  and 2N IP Intercom see please this FAQ: 2N® Indoor Touch - How to setup call from/to 2N® 2N IP Intercom? 


In order to perform correctly, all components are required to be interconnected over appropriate Ethernet/Wi-Fi network parts as described in this FAQ: Network requirements - What LAN/Wi-Fi infrastructure do I need?.

It is high recommended to use a physically dedicated LAN or a virtually dedicated VLAN with corresponding parameters. Insufficiently dimensed network infrastructure and active network parts may cause an overload of the network communication such as packets loss or delays with a direct impact on the communication smoothness.
