Industrial Applications

1. High-Speed Defect Detection in Manufacturing

The camera's 3.2 MP resolution at 120 fps, combined with a global shutter, makes it ideal for capturing fast-moving objects on production lines to detect subtle defects such as scratches, blemishes, or misalignments. The high frame rate ensures no object is missed, while the global shutter prevents motion blur.

Problem Solved

Ensures rapid and accurate quality control in high-volume manufacturing, reducing faulty products and increasing throughput.
