The DIS-2/M NSU is a network memory module for audio and video streams. It is able to receive audio and video streams in various encodings via an Ethernet network (unicast or multicast), to save them on the internal hard disk, and to transmit them simultanoeusly as stream. The evaluation of the saved live stream is possible at any time on a workstation via Ethernet (e.g. with SMAVIA Viewing Client or SeMSy^® III). Using a licence code the basic version with one IP audio and video channel can be expanded up to 2 IP channels.

The DIS-2/M NSU is designed for installation and operation in a 19" module rack. In the case of a service, the DIS-2/M UTP modules can be quickly and easily exchanged (hot-plug functionality).
