4-Port, GigE Vision, Power over Ethernet Frame Grabber Device—The PCIe‑8233 is a GigE Vision frame grabber featuring Power over Ethernet (PoE) technology. It provides optimized performance of high-resolution and high-frame-rate cameras through the combination of independent Gigabit Ethernet ports and NI’s high-performance GigE Vision driver. PoE reduces the need for additional external power supplies by powering cameras over the Ethernet bus, which simplifies system design and cabling complexity.
