Understanding NDI
Send video over network cable instead of long HDMI runs.
If you've never heard of NDI before, don't worry — you don't need to be a tech expert to use it. CueDirector handles most of the setup for you. Here's just enough to understand what it is and why it makes your life easier.
NDI (Network Device Interface) is a technology that sends video over a standard network cable — the same kind already used in most schools and theaters. Instead of running long HDMI cables from your computer to every screen in the building, CueDirector sends video over your existing network, and inexpensive NDI decoders at each screen convert it back to HDMI. Plug the decoder into your network and into your screen, and you're done.
This approach has some big advantages over traditional HDMI cables. CueDirector can simultaneously send different video to multiple destinations at once — a backdrop screen on stage, a monitor in the wings, a TV in the green room, and a display in the lobby — all over a single network connection. No specialized video cards, no long cable runs, no signal degradation. If you can plug in a network cable, you can add a screen.
NDI Decoders
Small box, simple setup.
An NDI decoder is a small, inexpensive device — about the size of a deck of cards — that connects to your network with one cable and to your screen or projector with an HDMI cable. That's it. CueDirector sees it automatically and handles the rest. Most schools already have the network infrastructure needed, which means getting started is mostly a matter of plugging things in.
NDI Cameras and PTZ
Direct multiple cameras from the same screen you already use to run the show.
CueDirector also supports NDI cameras for recording and directing your performances. Many of these cameras are PTZ cameras — PTZ stands for Pan, Tilt, and Zoom. That simply means the camera can move left and right, up and down, and zoom in and out — all without anyone physically touching it. CueDirector controls the camera movement directly, so one person can direct multiple cameras from the same screen they're already using to run the show.
Like the decoders, NDI cameras connect to your network with a standard cable. CueDirector finds them automatically — no complicated configuration required.
Power over Ethernet
One cable can carry power and video.
When shopping for NDI cameras, look for ones that support PoE, or Power over Ethernet. This simply means the camera gets its power through the same network cable that carries the video — no separate power outlet needed at the camera. This is a big deal when mounting cameras in places like the back of the auditorium or high on a lighting truss, where running a power cable would be difficult. One cable does everything.
To use PoE cameras, your network switch needs to support PoE as well. These switches are widely available, clearly labeled, and not expensive. Just make sure it has enough PoE ports for the number of cameras you plan to connect — and when in doubt, buy one with a few extra ports to room to grow.
PTZ Cameras
FoMaKo
For PTZ cameras, we recommend taking a look at FoMaKo. They offer solid NDI camera options at around $450 on Amazon — a fraction of the cost of professional broadcast cameras, and more than capable for school and community theater productions. FoMaKo cameras support PoE, so setup is as simple as running a single network cable to wherever you want the camera mounted.
NDI Decoders
NDI Go
For NDI decoders, we recommend the NDI Go, available on Amazon for around $169. Setup is straightforward, and they work reliably right out of the box. One particularly nice feature — NDI Go decoders can also be powered via PoE, just like the cameras. That means if your screen or projector is in a location without a nearby power outlet, you may not need one at all. Just run a network cable from your PoE switch, and the decoder powers itself.
Together, a FoMaKo camera and an NDI Go decoder give you a clean, professional camera setup for around $620 per camera position — a remarkably low cost of entry for capabilities that simply weren't accessible to school theater programs a few years ago.
