KEY ADVANTAGES
Bring 2-channel AHD-over-coax video into a USB workflow
Dual-Channel AHD Input2 × BNC AHD video inputs accept AHD-HD / AHD-FHD signals for convenient multi-camera connection.
Up to 1080p30Input and capture specifications up to 1080p30 support multi-channel monitoring, recording, and digitization.
Reuse Coaxial InfrastructureAHD carries HD analog video over coax, helping surveillance upgrades retain existing cabling.
UVC Plug and PlayUSB Video Class compliance enables compatible capture and streaming software to recognize the device without a proprietary driver.
Automatic Detection and ScalingThe device detects the input format and converts video to the output size requested by the application.
Low Power and SDKUSB bus power, consumption no greater than 1 W, standard interfaces, and a secondary-development SDK.
MULTI-CHANNEL ANALOG HD CAPTURE
Compact dual-channel AHD USB 3.0 capture box
Multiple BNC coax inputs · USB bus power · No audio / no loop-through
The silver metal enclosure suits desktop, rack-adjacent, and embedded deployments. 2 BNC inputs receive AHD video, while the USB 3.0 Type-B port connects to the capture host for consolidated multi-camera ingest.
2 × BNC AHD video inputs
Input and capture up to 1080p30; YUY2 output
USB 3.0 / USB 3.1 Gen 1, 5 Gb/s; USB 2.0 compatible
No audio capture and no video loop-through
AHD-OVER-COAX VALUE
Multi-channel ingest with HD images and existing infrastructure
AHD carries high-definition analog video over coaxial cable and helps bring conventional surveillance cameras into computer software. Projects with existing coax can reduce recabling needs while consolidating multi-view monitoring, recording, streaming, or algorithmic analysis in a USB capture workflow.
Consolidated Multi-Channel IngestBring 2 AHD feeds into a Windows or Linux host for software-based preview, recording, and management.
Reuse Coaxial CablingBNC connections accommodate AHD cameras and installed coax; actual transmission depends on cable, connectors, and source quality.
Standard UVC WorkflowConvert AHD video into standard UVC streams for compatible recording, streaming, and vision-analysis applications.
