Capture Specifications

The ESTONE OZC4-1 captures HDMI sources at up to 4K 60 Hz input and records at 1080p 60 Hz over USB 3.0. It also provides an HDMI loop-out at 4K 30 Hz or 1080p 120 Hz for a local monitor. The MS2131 chipset handles MJPEG and YUY2 formats for broad software support.

Thermal and Power Profile

The aluminium alloy body acts as a passive heatsink, so the unit runs silently with no fan noise. Power is drawn entirely from the USB 3.0 connection, removing the need for an external adapter. Typical operation stays cool during standard streaming or recording sessions.

Sustained Load Behaviour

During long captures the passive cooling keeps temperatures stable without throttling the 5 Gbps USB link. Audio pass-through via the 3.5 mm ports remains synchronised over extended periods. The device maintains low-latency preview and consistent frame delivery for hours of continuous use.

Questions about this item

How do I install the ESTONE OZC4-1 and which step causes issues?

Connect the source to the HDMI input, the display to the HDMI loop-out, and the USB 3.0 cable to the PC. The common mistake is using a USB 2.0 port, which cannot sustain the 5 Gbps bandwidth required for 1080p 60 fps capture.

What maintenance or replacement will the OZC4-1 need over time?

The aluminium enclosure and MS2131 chipset have no moving parts, so no scheduled maintenance is required. Only the USB 3.0 cable or HDMI cables may need replacement if connectors wear or cables are damaged.

What limit appears first during long streaming sessions with the OZC4-1?

The HDMI loop-out is limited to 4K 30 fps or 1080p 120 Hz, so extended 4K 60 Hz pass-through to a monitor is not possible; the capture output itself remains at 1080p 60 fps.
