What this capture card does

The ESTONE OZC4 is a USB 3.0 video capture device that accepts HDMI input up to 4K at 60 fps and streams 1080p at 60 fps to a host computer. It also provides an HDMI loop-out at up to 4K at 30 fps so the source signal can reach a display while recording. A 3.5 mm jack adds microphone input and headphone monitoring for live commentary. The aluminium shell runs without external power.

Thermals noise and power

The unit draws power directly from the USB connection and has no fan, so it adds no audible noise to a streaming setup. Passive cooling through the aluminium casing keeps surface temperatures low during typical 1080p60 capture sessions. Because it operates within standard USB 2.0 or 3.0 power limits, it does not require a separate adapter or a high-wattage port.

Who should look elsewhere

Creators who need to record or stream at 4K60 over USB will not get that throughput from this device, since the USB link tops out at 1080p60. Users who require multi-channel audio mixing, hardware encoding offload, or internal PCIe installation should consider a different form factor. The single HDMI input also means it cannot switch between multiple sources without an external splitter.

Questions about this item

How do I install the ESTONE OZC4 capture card, and which step is often missed?

Connect the source to the HDMI input, the display to the HDMI output, then plug the USB 3.0 cable into a USB 3.0 port. The step people miss is using a USB 2.0 port, which limits capture to 1080p@60fps instead of 4K@30fps.

What maintenance or replacement will the ESTONE OZC4 need later?

The aluminium alloy shell is passively cooled with no moving parts, so no routine maintenance is required. Only the USB 3.0 cable or 3.5 mm audio cables may need replacement if they become damaged.

What limit appears first during a long streaming session with the ESTONE OZC4?

The USB 2.0 fallback caps capture at 1080p@60fps, while the HDMI loop-out stays at 4K@30fps. Sustained use on a USB 3.0 port maintains 1080p@60fps capture without thermal throttling.
