For a normal Teams, Zoom or Google Meet room, a USB conference camera is the right choice: the computer or room system sees it as a webcam. You need a camera with HDMI, SDI or IP (network) output when the video goes somewhere other than a PC, such as a hardware codec, video switcher, recorder, lecture-capture system or live stream. Hybrid PTZ cameras like the AVer PTZ310UV2 do USB and HDMI/SDI/IP at the same time.
USB vs HDMI vs SDI vs IP
| Output | What receives it | Max practical run | Good for | Watch out for |
|---|---|---|---|---|
| USB (UVC) | PC, Mac, Teams/Zoom Rooms compute, USB bar | ~16 ft (5 m) passive; longer with active or optical extenders | Teams, Zoom, Meet, BYOD | Cable length; one app uses it at a time |
| HDMI | Displays, capture cards, switchers, recorders | ~25-50 ft depending on cable; longer with HDBaseT | Live production, local display, capture | Not a webcam on its own; needs a capture device for PC use |
| 3G/12G-SDI | Broadcast switchers, recorders | Hundreds of feet on coax | Churches, halls, broadcast | Needs SDI gear |
| IP (RTSP, RTMP, SRT, NDI) | Network recorders, streaming encoders, NDI software, VMS | Anywhere on the network | Lecture capture, streaming, multi-room production | Network bandwidth, latency, configuration |
USB cameras show up as UVC devices, so Teams or Zoom can control framing and many can pan/tilt/zoom from within the app. HDMI is just a video signal. A PC can't use it as a camera without a USB capture device.
When USB is enough
- The room runs Teams Rooms on Windows, Zoom Rooms on a PC, or a laptop for BYOD.
- The camera is within normal USB reach of the computer, or you use an active extender like Logitech Strong USB.
- You don't need to record or stream to anything besides the meeting app.
Most meeting-room PTZ cameras fall here: the AVer CAM520 Pro3, AVer CAM570 and the camera in Logitech Rally Plus. Video bars are USB too when used in BYOD mode. More in USB conference cameras.
When you need HDMI, SDI or IP
- Live streaming to YouTube, Facebook or a church platform through an encoder or software like OBS or vMix.
- Production switchers mixing several cameras.
- Lecture capture that records the room independently of the meeting.
- Hardware codecs and some room systems that take HDMI camera input. For example, the Poly G7500 accepts external cameras over HDMI.
- Long cable runs in auditoriums where USB extension is impractical.
Hybrid cameras: USB plus HDMI/SDI/IP
Many PTZ cameras send video out several ports at once. One camera can feed a Zoom call over USB while the same image goes to a stream over IP or to a recorder over HDMI.
| Camera | Outputs | Use |
|---|---|---|
| AVer PTZ310UV2 | USB, HDMI, SDI, IP, NDI, PoE+ | 4K60 12x PTZ for large rooms and classrooms |
| AVer PTZ330UV2 | USB, HDMI, SDI, IP, NDI | 4K60 30x PTZ for halls and worship spaces |
| Poly Studio E60 | See product guide | 4K 12x PTZ with presenter tracking |
Check each camera's guide for exact port behavior, since some outputs change resolution or frame rate when used together: PTZ310UV2 guide, PTZ330UV2 guide, Studio E60 guide.
"IP camera" for a conference room: two meanings
People searching for an IP conference camera usually mean one of two things:
- A PTZ camera with network streaming (RTSP, RTMP, SRT or NDI) and network control (VISCA over IP). These are production cameras. See AVer VISCA, NDI and RTSP control.
- A security-style IP camera. CCTV cameras are built for surveillance, not meetings. They typically lack the low latency, audio and UVC support that meeting apps need. See PTZ vs CCTV cameras and security-brand conference cameras.
Meeting apps on a PC don't use RTSP or NDI streams directly as a camera without extra software. If the goal is a Teams or Zoom call, use USB.
Typical setups
- Standard meeting room: USB PTZ or video bar to the room PC. Done.
- Hybrid church service: PTZ with SDI or NDI to a switcher for the stream, plus USB to a laptop for a Zoom feed. See church live stream camera setup.
- Lecture hall: PTZ with presenter tracking, USB to the room PC for Teams/Zoom, IP stream to lecture capture. See classroom video conferencing.
