NDI PTZ Cameras and Controllers

NDI PTZ cameras can help cut down on equipment, cabling and complexity of your video environment. NDI stands for “Network Device Interface,” which represents a proprietary set of tools and protocols created by NewTek, that facilitate the transmission of high-resolution video over a fast, low-latency network.

NDI is ideal for transporting high-resolution video with low latency, which means you don’t drop any frames or lose any quality in the transmission between devices. It’s designed to work over Gigabit Ethernet networks to allow up to 4K resolution video to transport with little to no latency, and it is very easily integrated with software control applications like vMix and Internet broadcasting.

FULL NDI – High Bandwidth NDI

FULL NDI is designed to support higher resolution, broadcast-quality video and uses I-Frame encoding. Provides single-frame delay and requires a GbE network and router. The following estimate of bandwidth load per NDI video stream is from the NewTek documentation “Adding NDI to your network”:
1 x stream 1080p50/59.94 video = 125Mbps
1 x stream 720p50/59.94 video = 90Mbps
1 x stream UHDp30 video = 200Mbps
1 x stream 1080i50/59.94 video = 100Mbps
1 x stream UHDp60 video = 250Mbps

NDI|Hx – Low Bandwidth NDI

Highlight of NDI HX is the low bandwidth requirements which allow users on simple Gigabit networks the ability to host multiple video streams without tying up to much network traffic. NDI HX @1080p30 typically requires about 10-20Mb/s.

The newest NDI|HX version, NDI|HX3 is an option for better video with reduced latency – using a fraction of the bandwidth of Full NDI high bandwidth. Software applications, such as NewTek TriCaster, Vizrt Vectar Plus, vMix, etc., will not need any upgrade to support NDI | HX3.
