NDI® (Network Device Interface) is an open protocol launched by NewTek™ in 2015 to allow on a network multiple video systems to identify and communicate with one another to easily and efficiently share video (to encode, transmit and receive many streams of high quality, low latency, frame-accurate video and audio in realtime)


This new protocol can benefit any network-connected video device, including video mixers, graphics systems, capture cards, and many other production devices. It also includes tools that implement video access rights, grouping, bi-directional metadata and IP commands. (NDI supports bi-directional transmission meaning that each device can serve as a source and/or receiver, for instance a camera can send a video but can receive control commands, all over NDI)


The IP-based connection makes large-scale deployments possible, including remote production... all based on an inexpensive infrastructure made of CATx network cables!


Concretely, NDI:

  • allows you to send video, audio, tally light and control (PTZ, presets, focus for instance) over the entire local network, and even further (WAN, internet)!
  • offers an optimized/low IP latency (optimizing the decoding buffer)
  • especially supports the function of auto-discovery (identifying automatically the NDI sources without the need of entering IP addresses manually) that simplifies installation and requires less IP knowledge. So it will help you to save a lot of time on setting up which can be ideal for instance for mobile (rental) setups.
  • and finally optimizes the interoperability between numerous brands supporting NDI

If you want to know the difference between NDI® and NDI®| HX we would refer to that other article


At Avonic, we have the CM70-NDI camera supporting NDI®| HX in black as in white color.
