Neousys PCIe-PoE352at 2-Port Server-Grade Gigabit 802.3at PoE+ Frame Grabber Card

A two-camera inspection station or a pair of PTZ surveillance cameras needs power and data on each cable, without adding adapters or extra wiring inside the host. The PCIe-PoE352at is the two-port build in the Neousys PCIe-PoE-at series: a PoE+ frame grabber card that takes all its PoE power from the PCI Express slot.

Two independent Gigabit Ethernet ports run from an Intel I350-AM2 controller, with checksum offloading, segmentation offloading and interrupt moderation to reduce CPU utilisation. The ports support 9.5 kB jumbo frames, teaming and IEEE 1588. The card connects over Gen2 PCI Express x4 with 2GB/s total bandwidth, and its single-bus, multi-port design minimises compatibility issues with off-the-shelf motherboards when several cards are installed. Cable runs reach 100 metres over CAT-5e or CAT-6.

Each port delivers up to 25.5 W under IEEE 802.3at-2009, and PoE+ power can be switched on or off per port. The 12 V for powered devices comes directly from the PCI Express bus, so no external 12 V feed is needed. That suits machine vision cameras and PTZ surveillance cameras. The PCIe-PoE354at doubles the port count to four, and the low-profile PCIe-PoE334LP suits 2U servers. Our FAQ on how much power PoE delivers sets out the figures.

From the bus, the card draws a maximum of 0.9 A at 3.3 V and 4.8 A at 12 V. It operates from 0 to 55 °C, uses a heat sink over the controller and measures 168 x 111 mm. Neousys shows CE and FCC marks on the datasheet. Machine vision is the main application Neousys names, with PTZ cameras for surveillance also covered by the 25.5 W per-port figure. We supply the card on its own or fit it to vision systems we build, and a two-port card keeps the power draw from the slot modest.
