Four Channel HDMI Capture Card
A wide range of applications demand multiple channels of video capture from a single card — advanced medical and machine vision capture, military applications, and security/surveillance systems among them. The XtremeDV-HD4+ audio/video capture card provides a powerful solution for multiple HDMI or DVI video capture with HDCP support, suited to exactly these markets.
The card has four channels of HDMI 1.4 — two supporting 297MHz (3840×2160 @60fps) and two supporting 165MHz (1920×1080 @60fps) — all operating independently, enabling four separate video sources to be captured and controlled simultaneously. Embedded audio is supported across all four channels, and the card is also available with DVI adapter cables on request.
The mixed-resolution channel layout — two 4K-capable, two HD-capable — makes the XtremeDV-HD4+ a good fit where a single system needs to capture from a mix of source qualities simultaneously, such as a medical imaging suite combining a 4K endoscopy feed with lower-resolution monitoring displays, or a security control room mixing high-res and legacy camera feeds on one card. If every channel needs to run at full 4K simultaneously, the dual-channel XtremeDV-UHD2 (two cards) delivers more consistent per-channel bandwidth than trying to push four channels at once.
Shipped with adapter cables for either HDMI or DVI — order as XtremeDV-HD4+/H for the HDMI splitter cable set, or XtremeDV-HD4+/D for the DVI splitter cable set, depending on your source connectors.
