NI IMAQ PXI-1411 Image Acquisition Module

The NI IMAQ PXI-1411 is a single-channel analog video acquisition module for PXI, PCI, and CompactPCI chassis. It captures and digitizes composite and S-Video signals from monochrome and color cameras, delivering real-time image data via a high-speed PCI interface. The module integrates a precision analog video decoder, onboard color processing with HSL conversion, and programmable acquisition control—making it ideal for machine vision, scientific imaging, and automated inspection systems.
