PROFESSIONAL VIDEO CAPTURE
Quad-Channel CVBS PCIe Video Capture Card
A four-channel capture solution for analog video integration and legacy-system upgrades. Integrated hardware deinterlacing converts PAL and NTSC interlaced video into progressive frames, enabling capture at up to 50 fps for PAL and 59.94/60 fps for NTSC. One internal PCIe card connects four CVBS sources for monitoring, recording, analysis, and professional system integration.

KEY ADVANTAGES
Key Advantages
Four Analog Video InputsFour BNC connectors accept four CVBS sources, allowing multiple analog devices to be consolidated in one host system.
PAL / NTSC CompatibilitySupports the widely used PAL and NTSC standard-definition composite video formats found across regions and legacy equipment.
Hardware DeinterlacingDedicated hardware converts interlaced PAL/NTSC fields into progressive frames, reducing combing artifacts during motion without relying on host-side software deinterlacing.
50 / 60 fps Progressive CaptureAfter hardware deinterlacing, PAL can be captured at up to 50 fps and NTSC at up to 59.94/60 fps for smoother motion.
High-Density Internal IntegrationOne internal PCIe card consolidates four inputs, reducing external capture devices and simplifying workstation or industrial-PC integration.
Built for Legacy-System UpgradesConnect analog cameras, inspection systems, medical video equipment, and playback devices to modern computing platforms.
4-CHANNEL CVBS CAPTURE
Quad-Channel CVBS PCIe Video Capture Card
4-Channel Analog Composite Video Capture
Designed for multi-channel standard-definition analog capture, the card provides four BNC CVBS inputs and integrated hardware deinterlacing. Progressive video at up to 50/60 fps is transferred to the host through PCI Express for smooth preview, recording, digitization, analysis, or custom application development.
4 × BNC CVBS video inputs
PAL: 720 × 576, hardware deinterlaced, up to 50 fps
NTSC: 720 × 480, hardware deinterlaced, up to 59.94/60 fps
Hardware deinterlacing for smooth 50/60 fps capture
PAL / NTSC VIDEO STANDARDS
CVBS Standards and Capture Formats
CVBS is a standard-definition analog composite format. PAL and NTSC are interlaced systems. The source contains 25/29.97 frames per second and 50/59.94 fields per second; integrated hardware deinterlacing converts those fields into progressive video at up to 50/59.94 (60) frames per second.
PAL
