Neousys NRU-52S NVIDIA Jetson Orin NX and Xavier NX Fanless Embedded PCs with 4x PoE++

Pan-tilt-zoom domes, heated outdoor cameras and illuminators draw more power than standard PoE+ can supply, so many video analytics sites end up with a separate PoE++ switch and injectors next to the computer. The Neousys NRU-52S series puts four IEEE 802.3bt PoE++ ports with screw locks straight into a fanless Jetson computer, each able to supply up to 90 W to one camera, in a small fanless case for use in a roadside cabinet, a vehicle or rolling stock.

The four ports run on one network through a built-in layer 2 switch and share 1 Gbps of total bandwidth, which suits camera streams. On board, the Jetson decodes up to eighteen 1080p streams at 30 fps with the Orin NX and runs detection, tracking and recognition models on its GPU and deep learning accelerators. The PoE budget scales with cooling: 50 W across the ports when passively cooled, or 144 W with the optional fan kit, both at -25 °C to 70 °C in the 15 W mode.

There are two versions. The NRU-52S+ runs an NVIDIA Jetson Orin NX (8 or 16 GB LPDDR5) or Orin Nano (4 or 8 GB), with JetPack 5.1.1 and a 128 GB M.2 2242 NVMe SSD fitted through a mini PCIe adapter, and delivers 100 TOPS with the Orin NX 16 GB. The NRU-52S runs the Jetson Xavier NX with 8 or 16 GB LPDDR4x, 16 GB of eMMC on the module and JetPack 4.6.1.

Both share two USB 3.1 Gen 1 ports, a DisplayPort output at 3840 x 2160, an RS-232/422/485 port and an isolated CAN 2.0 port on DB9, and three isolated inputs, four isolated outputs and a GPS PPS input on a DB15. Two full-size mini PCIe sockets take NVMe, Wi-Fi, GNSS, V2X or CAN modules, and an M.2 B key socket with dual micro SIM takes a 4G LTE or 5G NR module, with five antenna holes. Power is 8 to 35 V DC with ignition control. The series meets MIL-STD-810H for vibration and shock and EN 50121-3 for EMC, and Neousys lists it as MIL-STD-810H and EN 50155 certified.
