USB 3.0 HDMI capture device for streaming

This USB 3.0 capture device accepts an HDMI signal and streams it to a PC at up to 4K 30Hz or 1080p 120Hz with low latency. It supports 2-channel PCM audio and works with Windows 7 or later plus macOS 10.9 or later. No driver installation is required and the unit is FCC, CE and RoHS compliant. It suits gamers, meeting hosts and live-streamers who need a simple capture path.

Sustained capture at 4K 30Hz or 1080p 120Hz

The device maintains its rated resolutions continuously over USB 3.0 without frame drops caused by thermal throttling. Captured formats include YUY2, RGB32 and NV12 in both progressive and interlaced modes. Latency stays low during long sessions, making it reliable for extended broadcasts or recording. HDCP-encrypted content such as commercial movies cannot be captured.

Replaces internal capture cards

It upgrades from a PCIe card by removing the need to open the case and from USB 2.0 devices by adding 1080p 120Hz throughput. The jump is worth it when you want driver-free operation on Windows or macOS and compatibility with UVC and UAC software like OBS, Zoom or VLC. Buyers who need to record HDCP-protected video or require built-in encoding hardware should look elsewhere.

Questions about this item

Does the USB 3.0 capture device get hot or draw much power during long streaming sessions?

The unit is bus-powered over USB 3.0 and has no fan, so it stays cool and draws little power even during extended captures.

What cables or ports must I already have to use this capture device?

You need an HDMI source, a spare USB 3.0 Type-A port on the computer, and an HDMI cable to connect the two.

Will this capture card work with my older Windows 7 laptop for recording gameplay?

Yes, the device is driver-free and supports Windows 7 or later, so it will capture 1080p 120 Hz or 4K 30 Hz on that laptop.
