Four-Channel HDMI Capture

The Acasis PCIe 2.0 x4 card captures four independent HDMI sources at up to 1920x1080p 60 frames per second. It targets streamers, educators and broadcasters who need simultaneous multi-camera input for live production or conferencing. Hardware H.264 Main profile encoding offloads compression from the host CPU. Multiple cards can operate in one system for expanded channel counts.

Thermals and Power

Maximum power draw is listed at 5 watts, so the card runs cool inside a typical chassis without auxiliary power connectors. The operating range spans minus 20 to 85 degrees Celsius, and relative humidity tolerance reaches 90 percent. A passive heatsink handles the thermal load silently, adding no audible noise to a quiet studio or office environment.

Build Integration

The half-height board measures 100 by 86 millimetres and occupies a single PCIe 2.0 x4 slot, compatible with x4, x8 or x16 mechanical slots. No external power cable is required. Drivers support Windows 7, 10, 11 and Linux with DirectShow, DirectSound and V4L2 interfaces for OBS, Zoom, Teams and similar software. Four HDMI inputs free up USB bandwidth and eliminate the need for multiple external dongles.

Questions about this item

How do I install the Acasis 4-channel capture card in a PCIe 2.0 x4 slot?

Power off the PC, open the case, insert the card into a PCIe 2.0 x4 slot, secure the bracket screw, connect up to four HDMI sources, then boot into Windows 7, 10, 11 or Linux where the card is recognised automatically.

What maintenance or replacement will the card need later?

The card has no moving parts or DDR cache; keep the HDMI ports and slot contacts dust-free with compressed air, and ensure chassis airflow keeps the operating temperature below 85 Celsius — no scheduled component replacement is required.

What limit appears first during sustained 4-channel 1080p60 capture?

The PCIe 2.0 x4 host bandwidth and the hardware H.264 Main-profile encoder set the ceiling; sustained capture at 1920x1080p 60 fps on all four channels simultaneously is the practical maximum before frame drops or latency rises above 80 ms.
