What the ESTONE OZC3-3 captures

The ESTONE OZC3-3 is a USB 3.0 video capture device that accepts HDMI input up to 4K at 30 Hz and records at 1080p 60 fps. It is aimed at streamers and content creators who need a compact box for game footage from consoles or cameras. The aluminium housing provides passive cooling during long sessions.

Sustained-load behaviour

The unit uses USB 3.0 bandwidth to maintain a steady 1080p 60 fps capture stream without dropping frames during extended broadcasts. An HDMI loop-out passes the source signal through at 4K 30 Hz so the connected display stays in sync. Passive aluminium construction keeps temperatures stable without fan noise.

Check before ordering

Verify that your source device outputs HDMI at 4K 30 Hz or 1080p 60 fps and that your host has a free USB 3.0 Type-A or Type-C port. The 3.5 mm microphone input and headphone output require standard TRS plugs for live commentary monitoring. No external power adapter is included; the device draws power from the USB connection.

Questions about this item

How hot or noisy does the OZC3-3 get when streaming all day?

The aluminum-alloy body passively dissipates heat with no fan, so it stays silent and only warm to the touch during continuous 4K@30 or 1080p@60 capture.

Which cables and ports must I already have on my PC or console for the OZC3-3 to work?

You need an HDMI output on the source device and either a USB 3.0 Type-A or USB-C port on the host; the box includes both cable types.

Will the OZC3-3 pass 4K@30 through to my older 1080p monitor while I record?

Yes, the HDMI loop-out mirrors the incoming 4K@30 signal so your existing 1080p display receives a compatible picture while the capture runs at 1080p@60.
