A Smarter Hybrid Conference Setup: 10 Mics, 4 PTZ NDI Cameras, and a Biamp Tesira Brain

A Smarter Hybrid Conference Rig That Thinks For Itself

Hybrid meetings shouldn’t feel like a compromise. At AVE Services, we’ve built a portable rack that brings broadcast-grade audio and video into boardrooms and town halls with minimal fuss: 10 microphones, 4 NDI® PTZ cameras, a Biamp Tesira DSP at the core, and Dante® to move pristine audio to a vMix laptop for recording and live delivery to Microsoft Teams or Zoom. The result is a system that looks after itself—picking the right mic, framing the speaker, and keeping the call clean—so your team can just talk.

At the heart of the rack sits Biamp’s Tesira platform, where the audio intelligence lives. Tesira’s toolset includes acoustic echo cancellation (AEC) to remove room and far-end echo paths, automixing to open the right mic at the right moment while keeping others suppressed, and automatic gain control (AGC) and compression to even out levels between quiet and confident voices.

From there, the audio rides the network over Dante, Audinate’s widely adopted audio-over-IP standard. Dante replaces point-to-point analogue cabling with routable, low-latency audio on standard Ethernet, making it ideal for multi-mic boardrooms, larger town halls, and portable systems that need fast, reliable patching. For our workflows, Dante gives us channel-accurate routing, clocking, and the flexibility to scale—handy when a “small meeting” becomes a company-wide briefing.

Video is handled by four PTZ cameras speaking NDI, NewTek’s IP protocol for high-quality, low-latency video transport on standard networks. Because NDI carries tally and control, we can tie mic gating to PTZ presets—if Mic 1 opens, Camera 1 recalls the correct shot; if the chair speaks, the system cuts to a pre-framed close-up. NDI’s tooling (including NDI Studio Monitor) and wide support across modern PTZ ranges make networked camera control practical in real rooms, not just studios.

Everything converges in vMix, our production switcher and recorder. vMix takes Dante audio (via the interface on our laptop) and NDI camera feeds, giving us an operator-friendly surface for live switching, graphics, ISO and program recording, and simultaneous streaming. Critically, vMix also exposes a Virtual Camera/Audio path so the composed program can be selected inside Teams or Zoom, or sent as RTMP/SRT to a CDN for public webcasts. That lets us keep a single production brain for internal meetings, external webinars, or hybrid town halls without re-wiring.

On Microsoft’s side, Teams supports NDI workflows, allowing producers to route participant feeds on the local network. We more commonly present vMix’s program into Teams/Zoom via the virtual outputs, but the Teams NDI capability is there when a production needs discrete remote feeds or more advanced return paths. The key is that our rack keeps incoming and outgoing audio fully separated—classic mix-minus—so remote contributors hear the program without their own voice returning a split second later. Microsoft’s own guidance acknowledges how NDI in Teams exposes unique per-participant streams that production tools can ingest.

What does all this mean in the room? People can speak naturally. The system’s automix and AEC keep the table quiet and intelligible, while AGC and compression smooth out level jumps, so the far end hears consistent speech. Meanwhile, the PTZs quietly do their job in the background—speaker-follow video makes remote attendees feel included, because they see who’s talking, not just a wide shot of a table. And because audio and video are IP-based (Dante and NDI), we roll in, patch to the venue network where appropriate, and focus on content, not cabling. For comms teams, it’s also a win: vMix records locally for archives and compliance while pushing a clean, branded program feed live to Teams, Zoom, or your dedicated streaming platform.

If you’re planning a board meeting, town hall, training day, or press conference, this approach delivers broadcast polish with the reliability you need. We’ll frame your room, map the PTZ presets, tune the Tesira blocks, and set Dante routing so everything just works on the day—no drama, no feedback loops, and no scrambling for adapters five minutes before the CEO joins.

TL;DR (Plain English)

  • We bring a tidy AV rack that makes hybrid meetings look and sound like a proper broadcast without fuss.

  • Sound stays clear: it picks the person talking, turns down the rest, and stops echo so nobody hears themselves back.

  • Cameras move automatically: when someone talks, the nearest camera snaps to a good shot of them.

  • It plugs into Teams or Zoom and can record the whole thing at the same time.

  • Great for board meetings, town halls, training days, and press briefings. You talk. It just works.
