Summary: Learn how to choose between wireless and wired barcode scanners for inventory, traceability, fixed stations and high-frequency scanning tasks. Start from the workflow Wireless and wired barcode scanners can both read common codes, but they serve different operating styles. A wireless scanner is usually better when the operator must move around inventory racks, pallets, […]
Summary: Compare DPM, QR code and linear barcode reading conditions, including lighting, focus, surface quality and on-site validation needs. Different codes, different problems DPM codes, QR codes and linear barcodes are all used for traceability, but they behave differently on site. A DPM code is marked directly on a part by laser, dot peen or […]
Summary: Understand why digital lighting controllers should synchronize with camera exposure to reduce blur, ambient interference and unstable inspection images. Why timing matters Digital lighting controllers are used to manage brightness, channel output, strobe duration and switching logic in machine vision systems. When they operate independently from the camera, the inspection image may change from […]
Summary: Learn how ring lights, coaxial lights, bar lights and panel lights influence code reading stability, contrast and machine vision inspection reliability. Why lighting decides reading stability In machine vision projects, lighting is often the difference between a stable reading station and a line that works only under ideal conditions. A camera can only analyze […]
