CORE ADVANTAGES

Bring 4 AHD/CVBS feeds into a dependable PCIe workflow

Four-Channel Capture4 BNC inputs capture 4 AHD feeds simultaneously at up to 1080p30.

Multi-Format CompatibilitySupports AHD-HD, AHD-FHD, and AHD-CVBS for HD and legacy coax sources.

PCIe 2.0 x1 TransferA stable internal data path for continuously operating monitoring, analytics, and integration systems.

Multi-Stream and Multi-AppEach input can provide duplicated streams and can be accessed by multiple applications concurrently.

Multi-Card IDsMultiple cards can operate in one system; an onboard selector provides four IDs for device management.

Cross-Platform APIsSupports DirectShow/DirectKS on Windows, V4L2 on Linux, and secondary development.

INTERNAL CAPTURE VALUE

Four-channel ingest, coax deployment, and PCIe scalability

AHD carries high-definition video over coax and helps extend existing analog infrastructure. The internal PCIe architecture brings multiple camera feeds into host software for multiview monitoring, recording, streaming, algorithmic analysis, and centralized management.

Upgrade Coax SystemsConnect AHD cameras to Windows or Linux hosts for software-based recording, management, and analytics.

Stable Internal BusThe PCIe connection supports multi-channel video workstations and continuous operation.

Integration and ExpansionCard IDs, concurrent application access, and standard APIs support industrial, security, and OEM deployments.
