What the Elgato Cam Link Is
The Elgato Cam Link is a compact USB video capture device that converts HDMI output from cameras into a USB webcam signal that computers recognize. It’s widely used by streamers, content creators, and presenters who want to use higher-quality cameras for video calls and live streams without specialized capture cards.
Key Use Cases
Streaming & Broadcast
Use a DSLR, mirrorless, or professional camcorder as a webcam in OBS, Streamlabs, Zoom, Teams, or similar platforms to improve image quality over built-in webcams.
Video Calls & Conferencing
Elevate your virtual meetings by using a high-quality camera (Sony, Canon, Panasonic, etc.) instead of a laptop webcam.
Content Creation
Capture footage from action cams or other HDMI devices directly into recording software on your computer.
Models & Variants
Elgato has offered several versions, with the most common being the Cam Link 4K. It supports up to 4K30 input and 1080p60 capture over USB 3.0, providing flexibility depending on your resolution needs.
Strengths
- Simple plug-and-play: Recognized as a webcam on macOS/Windows with minimal setup.
- Compact & portable: USB dongle form factor fits easily in mobile setups.
- Broad camera compatibility: Works with many HDMI-enabled cameras from major brands.
- Low latency: Clean video feed with minimal delay in most configurations.
Limitations
- USB bandwidth constraint: 4K capture may be limited by USB throughput or host hardware.
- No passthrough: Some older models don’t allow HDMI passthrough to an external monitor.
- Driver reliance: macOS and Windows support can vary with OS updates; occasional driver or firmware updates are needed.
Tips for Best Performance
- Use a USB 3.0 port directly on your computer (avoid hubs for critical use).
- Match camera output settings to the capture resolution (e.g., 1080p60) to avoid scaling.
- Disable camera overlays and auto-power-off features to maintain a clean, consistent feed.
Alternatives to Consider
- Dedicated capture cards (PCIe) for multi-input or professional broadcast rigs.
- Other USB capture devices from brands like AVerMedia or Blackmagic.
- Cameras with (good) native USB webcam support (UVC) for simpler setups.
