 | For large rooms, boardrooms, classrooms, and multi‑purpose spaces, a single vantage point rarely captures the full “story.” Microsoft’s Multiple camera view for Teams Rooms on Windows lets you feed up to four simultaneous single‑stream USB camera views from the room PC to remote participants, who can then switch among views during the meeting for better situational awareness. This capability is Windows‑only today (distinct from classic “camera switching” or IntelliFrame’s multi‑stream AI cameras) and must be turned on by the tenant/room admin. However, it is widely expected that this capability will come to Teams Room on Android sometime in the future. This blogpost dives into how to design, deploy, and operate robust multi‑camera Microsoft Teams Rooms on Windows (MTRoW) using HP Poly components and reliable long‑distance USB transport. |
Key points to know about multi-camera support on MTR Windows
Important distinction
Microsoft IntelliFrame Multi-Stream (multi‑stream intelligent camera hardware) is different: it relies on AI camera hardware that generate multiple people streams; Multiple camera view expects separate single‑stream cameras connected to the MTR PC and shows parallel feeds remote users can toggle through.
MTR Windows Conferencing PC best suited for multi-Camera support on MTR Windows:
The HP Poly Studio G9 Plus base kit (which includes the HP Mini IP Conferencing PC and the Poly TC10 controller) is purpose‑built for MTRoW. It provides sufficient collaboration‑oriented ports, supports pairing with up to four Poly TC10 controllers over Ethernet via its LLN port, and is built on Windows 11 IoT with 13th Gen Intel® Core™ i7—a meaningful margin above Microsoft’s minimum CPU guidance for four cameras. With the 13th Gen i7 spec in the G9 Plus, you’re at or above Microsoft’s Intel 12th Gen recommendation for four cameras, helping ensure smooth multi‑stream encode/decode in meetings and reducing the risk of frozen feeds while future proofing your investment in the PC hardware for additional AI features that will be introduced in the future. Below is the picture of TC10 controller peripheral camera settings with 4 cameras attached via USB:
- Up to four single‑stream USB cameras; (multi‑stream intelligent cameras are not supported in this mode).
- Supported endpoints: Remote users on Teams desktop (Windows/Mac) can select the view they want while the meeting is running. In the future it is expected that other Teams Rooms on Windows endpoints will also be able select the view.
- Compute matters: Microsoft recommends at least an Intel Core i5, with 9th gen i5 minimum for 2–3 cameras, and 12th gen i5 minimum for 4 cameras. These requirements are about decoding/encoding multiple simultaneous streams and avoiding freezes.
- Bandwidth matters: Microsoft recommends direct USB connections to the room PC where possible, and cautions against putting more than one camera per hub due to USB bandwidth limits. (You can use a USB hub but keep cameras one‑per‑hub branch.)

During a Teams meetings, the Camera settings can be used to enable or disable multi camera view. Note that Enhanced framing must be enabled in order to enable multi camera. In addition, the different framing options - Intelliframe, Group framing and Active speaker are still available to be selected for the cameras that support these framing features. Below screen shot shows multi-camera enabled with no framing mode selected - this means each camera is using default position and zoom:
Below screen shot shows multi-camera enabled with Active speaker selected - this means those cameras that support this framing mode will be framing speakers:

Camera choices and roles: Poly Studio E70, Poly Studio E60, and Poly Studio V72
A successful multi‑camera design pairs complementary cameras for best room coverage. Think of each camera as covering a job:
Poly Studio E60 (Smart MPTZ with 12× optical zoom)
Poly Studio E70 (Dual 4K sensors; people framing champion)
Poly Studio V72 (Premium USB video bar for large rooms)
Cabling & transport: getting USB where it needs to be (Cat6/7 extenders)
Since all four cameras must be connected to the MTR PC via USB, and the cameras are likely spread throughout large rooms for maximum coverage, USB cabling distance becomes the silent constraint. Native USB‑3 cables top out at ~3 m for reliable 5 Gbps. In real rooms, you’ll likely need USB extenders over Cat6a/Cat7. Below are some enterprise‑class USB 2.0 / 3.x extenders validated in the professional AV world. These are highly relevant for multi‑camera Microsoft Teams Rooms deployments, especially when using high‑bandwidth devices such as Poly Studio E70, E60, and V72.
Conclusion
Building a multi‑camera Microsoft Teams Room on Windows is ultimately about getting the fundamentals right: compute, camera roles, and USB transport. The HP Poly G9 Plus provides the processing overhead needed for smooth multi‑camera performance, while the Poly Studio E70, E60, and V72 work together to deliver clear table views, reliable presenter tracking, and wide‑room context.
Because USB distance and bandwidth are often the biggest constraints, choosing the right extender—whether from Icron, Sound Control Technologies, INOGENI, Crestron, or Extron—is essential to maintaining stable, high‑quality video across long cable runs. These extenders ensure each camera performs consistently, allowing Teams’ Multiple camera view to function as intended
A successful multi‑camera design pairs complementary cameras for best room coverage. Think of each camera as covering a job:
- Presenter/lectern coverage (tight follow, high optical zoom): Studio E60
- People framing of the table (dual‑lens, wide + narrow, AI productions): Studio E70
- Room‑filling AIO bar for wide shots + integrated audio (and a large‑room option): Studio V72
Poly Studio E60 (Smart MPTZ with 12× optical zoom)
- Dual‑lens design: a panoramic lens + an MPTZ lens with 12× optical zoom for detailed presenter tracking and long‑throw clarity. Field of view ~71° (PTZ) / 107° (panoramic); 4K capture.
- Poly DirectorAI framing modes (Presenter Tracking, Group Framing) and PoE+ power option via RJ‑45 make it flexible to mount and power.
- Suitable roles: lectern/presenter camera or rear‑of‑room zoom camera in training rooms and lecture spaces.
Poly Studio E70 (Dual 4K sensors; people framing champion)
- Dual‑lens camera with 120° and 70° HFOV optics and an electronic privacy shutter. Designed for people framing and whole‑table coverage in larger rooms. Specs list USB‑C and RJ‑45 (PoE), plus people counting.
- HP/Poly documentation includes E70 Audio Service for MTRoW and integration guides (useful when fine‑tuning framing modes with Teams).
- Suitable roles: front‑of‑room main camera covering the table; pairs well with a secondary camera focused on presenter or whiteboard.
Poly Studio V72 (Premium USB video bar for large rooms)
- Dual 20MP 4K cameras (70° + 120° FOV), long‑range second‑order gradient microphones up to 25 ft, and high‑end stereo speakers—useful in large rooms that need integrated audio alongside multi‑camera video.
- While V72 is a USB bar (not an Android appliance), in PC‑based rooms it shines as either the anchor A/V device or a wide‑shot camera while E60/E70 handle special angles
