Elgato Cam Link 4K Review

The Elgato Cam Link 4K is an external USB dongle that turns a DSLR, mirrorless camera, or camcorder with clean HDMI output into a high-quality video source for streaming or video calls, at up to 4K30 or 1080p60.

Every other capture card in our catalog is built around console or PC gameplay capture, the Cam Link 4K solves a completely different problem, turning a DSLR, mirrorless camera, or camcorder into a webcam-quality video source for streaming or video calls through its HDMI output. If you already own a compatible camera with clean HDMI output, the image quality genuinely beats any built-in laptop webcam and even our dedicated webcam picks, provided you already own the camera. Ultra-low latency passthrough keeps the feed responsive in real time, which matters more here than for gameplay capture since this is often used for live calls and streaming.

Not a Gaming Capture Card, a Camera Bridge

If you already own a DSLR or mirrorless camera with clean HDMI output, the Cam Link 4K is how you get that image quality into OBS, Zoom, or Discord, genuinely better image quality than any built-in laptop webcam or even our dedicated webcam picks, provided you already own a compatible camera.

Ultra-Low Latency Matters More Here

Because this is often used for live video calls and streaming rather than pre-recorded footage, Elgato's low-latency passthrough keeps your camera feed responsive in real time, not just for gameplay capture.

Comparison to Alternatives

Against our own Elgato HD60 S+, the HD60 S+ is built for console/PC gameplay capture, the Cam Link 4K is specifically for camera-to-computer video bridging, different use cases entirely despite both being Elgato capture devices. Against our own Logitech MX Brio or Anker PowerConf C300 webcams, if you don't already own a compatible camera, a dedicated webcam is the simpler and cheaper path to better video quality.
