Versatile USB camera with AR0522 sensor

Alvium USB cameras are designed for use in both machine vision and embedded applications. Offering high image quality and reducing workload for the host, Alvium enables innovation among system designers. The innovative ALVIUM System on Chip (SoC) performs image corrections and preprocessing tasks onboard the camera instead of the host computer. Unlike FPGAs commonly used in machine vision cameras, the ALVIUM SoC is extremely power efficient. With Alvium, integrating hardware and software can be done effortlessly, which ultimately reduces development time. The ON Semi AR0522 CMOS sensor enables high-quality imaging at 5.1 megapixel and 67 frames per second with near infrared (NIR) enhancement. NIR enhanced models ship without a filter or protection glass.
