PROFESSIONAL USB VIDEO CAPTURE
Single-Channel AHD USB 3.0 External Video Capture Box
A compact external capture solution for Analog High Definition surveillance, existing coaxial-system upgrades, and professional video digitization. One BNC input accepts AHD-HD or AHD-FHD video at resolutions up to 1080p30. The device outputs standard YUY2 video over USB 3.0 and remains backward-compatible with USB 2.0. Class-compliant UVC operation enables driver-free use with Windows, Linux, and mainstream capture applications.

KEY ADVANTAGES
Bring AHD-over-coax video into a USB workflow
Single AHD InputOne BNC input accepts AHD-HD and AHD-FHD sources for connection to analog HD cameras and equipment.
Up to 1080p30Input and capture support resolutions up to 1080p30 for HD surveillance preview, recording, and analysis.
Reuse Coaxial InfrastructureAHD carries analog HD video over coaxial cabling, helping existing surveillance installations migrate without complete rewiring.
UVC Plug and PlayUSB Video Class compliance enables compatible capture and streaming applications to recognize the device without a proprietary driver.
Automatic Detection and ScalingThe device detects the incoming format and converts video to the output size requested by the application.
Low Power and SDKUSB bus powered with consumption up to 1 W, plus standard interfaces and SDK support for integration.

AHD-OVER-COAX VALUE
HD video while retaining existing surveillance infrastructure
AHD transports analog HD video over coaxial cabling and provides a practical path for bringing surveillance camera feeds into computer software. Existing installations can retain suitable coaxial infrastructure while adding USB-based preview, recording, streaming, or video analysis.
Surveillance UpgradesConnect an existing analog HD surveillance system to a Windows or Linux host for software-based recording and management.
Coaxial ConnectivityThe BNC input connects AHD cameras and coaxial runs; real-world transmission depends on cable, connectors, and source quality.
Software-Based WorkflowsConvert the AHD feed into a standard UVC stream for preview, recording, streaming, and computer-vision applications.
