LRES2680PT-POE is a high-performance quad-port PoE 5G vision frame grabber card developed by Linkreal Co., Ltd., based on the Realtek RTL8126 controller. Each RJ45 port supports up to 5Gbps data rate and 30W PoE+ output, with a total power budget of 90W.
The card is compliant with IEEE 802.3at PoE+ standard and features a resettable electronic fuse for reliable PoE protection. PoE power can be controlled via both hardware (physical) and software switches, providing flexible power management and enhanced safety. PoE software utilities allow real-time monitoring of port status and simplify system maintenance.
Optimized for image acquisition applications, the card supports multi-queue parallel processing, traffic shaping, and advanced network management functions, making it suitable for machine vision, intelligent surveillance, industrial automation, and traffic monitoring systems requiring high bandwidth and stable network performance.
