If you use 2N® Indoor Touch 2.0 as an answering unit for 2N® IP Intercom in the local network, the video stream from the 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® IP Intercoms can be received by the 2N® Indoor Touch 2.0 in the local network:

  1. Unicast (suitable for up to 3pcs of 2N® Indoor Touch 2.0)
     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® IP Intercom, no audio listen in (audio preview)

  2. Multicast (suitable for 3+pcs of 2N® Indoor TouchTouch 2.0)
    unlimited devices to watch the video stream from 2N® IP intercom, audio listen in (audio preview), optimised network bandwidth usage
    smart active network parts with multicast support required (especially for Wi-Fi)

...

  • LAN - a smart managed switch with the IGMP Snooping support to avoid overloading of the switch/network throughput.
  • Wi-Fi - access point with the multicast helper feature support (alternative names eg.: Wi-Fi multicast, Multicast Routing across Wi-Fi etc.), which can translate the multicast stream to a unicast stream and increase the transfer rate.

How to set 2N® Indoor Touch 2.0?

The configuration of video parameters can be found in the "Settings" section of the 2N® IP Mobile application. Go to the section "Settings - Video" in order to adjust the parameters (the factory default value is Unicast), see the pictures below.Image Removed Image Removed Image Removed

There is also an adjustable timeout for the video deactivation in a range of 1 - 30 minutes (the factory default value is 2 minutes). The 2N® IP Mobile application stops receiving of the Unicast/Multicast stream after exceeding of this timeout, see the picture below.

It is recommended to use a reasonably low value of the timeout in order to save the overall network bandwidth.
