A large conference room (about 12-20 seats, roughly 20-30 feet deep) needs a camera with optical or high-quality zoom to see the far end of the table, microphones spread along the table or in the ceiling, speakers that fill the room, and usually two displays. For rooms up to about 20 seats, a large-room video bar with expansion mics is often enough; beyond that, or for long boardroom tables, use a modular system with a PTZ camera, separate mics and speakers, and optionally multiple cameras.
Equipment for a large room
| Component | Recommendation |
|---|---|
| Camera | PTZ with optical zoom, or dual-camera bar; add a second camera for long tables |
| Microphones | 2-4 table mic pods or ceiling mic arrays, with echo cancellation |
| Speakers | Bar speakers for rooms up to ~20 ft deep; separate speakers beyond that |
| Displays | Dual displays (people + content), 75-98 in, or an LED wall |
| Compute | Appliance bar, or a Teams/Zoom Rooms PC for multi-camera |
| Control | Table touch controller |
| Content sharing | HDMI at the table plus wireless sharing |
Option 1: large-room video bar plus mics
Simplest to install and manage. Good for rooms up to about 20 seats.
| Bar | Notes | Expansion mics |
|---|---|---|
| Logitech Rally Bar | Motorized 4K PTZ, 15x zoom | Rally Mic Pod |
| Logitech Rally Bar 2 | 1-inch sensor 4K, 115-degree view | Rally Mic Pod 2 |
| Poly Studio X72 | Dual 4K cameras, all-in-one | Poly Studio Table Microphone |
| Neat Bar Pro | Dual 50 MP cameras, 16x hybrid zoom | Neat Center (360-degree camera and mic companion) |
| AVer VB350 | Dual-lens 4K PTZ USB bar, 18x zoom | AVer 20m Expansion Microphone |

Option 2: modular system
Best for long tables, high ceilings, or rooms over 25-30 ft deep.
- Logitech Rally Plus: 4K PTZ camera, two speakers and two mic pods; add pods and the Rally Mic Pod Hub. Needs a Teams/Zoom Rooms PC or Logitech RoomMate.
- Poly G7500: modular 4K codec with the Poly Studio E70 dual-lens camera and Poly IP Ceiling Microphone or IP Table Microphone.
- Poly Studio 7 Room Compute: Teams Rooms compute built for multi-camera rooms.
Cameras for large rooms
- PTZ cameras such as the AVer CAM570 (4K dual-lens, audio tracking, 36x zoom) or Logitech Rally AI Camera Pro (dual-camera PTZ, 15x hybrid zoom) frame people at the far end clearly.
- Multiple cameras let Teams Rooms and Zoom Rooms switch to the active speaker and show individual tiles. A front camera plus a companion such as the Logitech Sight covers people who face each other across a long table. See multi-camera conference rooms and Teams Rooms IntelliFrame.
- Webcams aren't suited to large rooms: their fixed wide lenses make the far end too small to see.
- Wireless cameras: room cameras are wired for reliability. "Wireless" large-room setups usually mean wireless content sharing or a wireless presenter mic. See wireless conference cameras.
Audio for large rooms
- Place one table mic per 6-8 seats (fewer seats per mic in echoey rooms), or use ceiling arrays over the table.
- Use one echo-cancelling audio path for the room (the bar, the codec, or a DSP).
- Add speakers near the display so remote voices come from the screen.
- Treat the room if it's echoey; large rooms usually are. See how to reduce echo and large conference room audio.
Displays and layout
- Two displays side by side: people on one, content on the other. See dual display conference room.
- Size displays so the farthest seat is within about 4-6 screen heights. See conference room TV size.
- A tapered or V-shaped table improves camera sightlines.
Cabling
Large rooms often need long USB or camera runs: use the Logitech Rally Camera Extension Kit, Logitech Strong USB or Mic Pod extension cables. See conference room wiring.
