LAN Camera Streaming for Confidence Monitors & Overflow Rooms
The main hall is full, and forty people are watching from the lobby. Or the speaker needs a confidence monitor at the podium showing exactly what the audience sees. Neither needs the internet — both just need a camera feed to move across the room.
What this actually requires
- A camera feed reaching one or more screens on the same venue network, reliably.
- Low enough latency that a confidence monitor doesn't feel delayed to the speaker.
- A way for overflow-room viewers to watch without installing software on borrowed or venue-owned displays.
- No dependency on venue internet, which is the least trustworthy utility in the building.
Option 1 — Cloud streaming (YouTube Live, etc.)
Works well for remote audiences outside the building, but is the wrong tool for a room forty meters away — it adds internet dependency, upload bandwidth requirements and streaming latency to a problem that's really just "move this feed across the hallway."
Option 2 — NDI / OBS
NDI is the professional standard for broadcast-quality video-over-IP, and OBS is a capable free production tool. Both are excellent — for a broadcast workflow. For a straightforward confidence monitor or an overflow-room screen, they bring setup overhead (OBS scenes, NDI-aware receivers on every downstream device) disproportionate to the task.
Option 3 — CueLink
CueLink is built specifically for moving a camera feed across a venue LAN with minimum friction:
- Sender and Receiver modes — install Sender where the camera is, Receiver (or a browser) wherever you need the feed.
- Browser viewer support — no app required on the viewing device; open a URL and watch.
- Quality presets — High (1080p), Balanced (720p), Low (480p) to match the network and screen.
- Adaptive bitrate and unlimited viewers (Pro) for larger overflow audiences.
- Audio streamed alongside video, with real-time VU metering.
- Zero internet dependency — fully LAN-based.
- Free tier available (1 viewer) — good enough for a single confidence monitor at no cost.

See CueLinkFrequently asked questions
Can I watch the stream on a smart TV or tablet in the overflow room?
Yes — the browser viewer works on any device with a modern browser on the same network, no app installation needed.
Is the free version enough for a backstage confidence monitor?
Yes — the free tier supports 1 viewer, which covers a single confidence monitor or backstage screen at no cost.
How many people can watch an overflow-room stream at once?
The Pro version removes the viewer limit and adds adaptive bitrate, suited to larger overflow audiences.
