4CH AHD 720p USB 2.0 Capture Card

The GRACETOP capture card accepts four analogue high-definition camera channels at up to 1280x720 resolution and 30 frames per second. It connects through a USB 2.0 interface and draws power from the host, so no external supply is required. The device presents itself as a standard UVC and UAC peripheral, making it ready for immediate use.

Suited for multi-camera monitoring

This unit fits users who need to bring four 720p AHD sources into a Windows, macOS or Linux machine for recording, teaching capture or medical imaging workflows. It works with common software such as OBS, PotPlayer and VLC without driver installation. Buyers requiring 1080p or 4K capture, higher frame rates at 1080p, or internal PCIe bandwidth should consider other form factors.

Handles four simultaneous 720p30 streams

Each channel records at 1280x720 and 30 fps directly to the host drive with minimal latency; the specification also notes 60 fps capability at 720p. The USB 2.0 link provides enough throughput for the stated four-channel load, but it will saturate before higher resolutions or additional channels can be added.
