Six-channel composite video capture — the analogue digitisation workhorse.
Ask us a quick question about this product — signal compatibility, use case fit, or anything technical. We usually reply the same day.
The Pro Capture Hexa CVBS is the digitisation workhorse for CCTV, security and analogue broadcast operations — six independent CVBS (composite) video channels with analogue audio on a single low-profile PCIe x1 card.
There remains a substantial installed base of CCTV and analogue video equipment in the UK that organisations would like to digitise without ripping out and replacing every camera. This card is built for exactly that: six BNC composite inputs, each running an independent PAL or NTSC channel, captured to file by software that sees six standard video devices.
Common deployments include legacy CCTV digitisation, archive operations transferring old analogue broadcast tape masters, and security control rooms that need analogue camera feeds available on a modern computer system for recording and remote monitoring.

The Pro Capture Hexa CVBS uses a Low-profile PCIe x1 slot. It will also fit in larger PCIe slots (x8, x16) as PCIe is backward compatible, but will run at the card's native lane width.
The Pro Capture Hexa CVBS is a capture card. Simultaneous playback (loop-through) depends on the specific model — check the Loop-Through spec in the full specification table. ForeFront Imaging can advise if you need simultaneous I/O.
The Pro Capture Hexa CVBS works with any software that supports DirectShow (Windows), V4L2 (Linux), or AVCaptureSession (macOS), including OBS Studio, vMix, Wirecast, Capture One, XSplit and most broadcast NLE software. Magewell's free Capture Express software is also available.
The Pro Capture Hexa CVBS accepts 6x CVBS (BNC) + analogue audio.
The Pro Capture Hexa CVBS captures at up to 625 lines PAL / 525 lines NTSC per channel.
Yes. Magewell Pro Capture cards are fully supported on Windows 10 and Windows 11. Driver downloads are available free from Magewell's website and from our Software page.
