The Sensoray 611 is a 4-input analog video frame grabber that converts composite and S-Video signals into digital data for computer processing and archival. Equipped with dual 8-bit flash A/D converters and 2x oversampling, the board captures video at up to 30 frames per second with independent X and Y scaling. It connects via 32-bit, 33 MHz PCI bus mastering and operates across PAL, SECAM, and NTSC standards. GPIO control via TTL I/O enables camera triggering and pan/tilt integration. This is a legacy product; new designs should evaluate current alternatives. Availability may be subject to lead times and minimum order requirements.
Technical Specifications
