Neousys NRU-52S+ NVIDIA Jetson Orin NX or Orin Nano Fanless Embedded PC with 4x 90W PoE++ and EN 50155

Rail platforms, road junctions and patrol vehicles increasingly run AI on the camera feeds where they are captured, and the cameras there are often PTZ domes or heated housings that need more than PoE+. The Neousys NRU-52S+ is a fanless video analytics computer with four IEEE 802.3bt PoE++ ports, each able to supply up to 90 W to one camera, in a mini PC-sized case. It is the Jetson Orin version of the NRU-52S series.

Compute is an NVIDIA Jetson Orin NX with 8 or 16 GB LPDDR5, or an Orin Nano with 4 or 8 GB, bundled with JetPack 5.1.1. With the Orin NX the NRU-52S+ decodes up to eighteen 1080p streams at 30 fps and delivers up to 100 TOPS for detection, tracking and recognition, at around 25 W. Every ordering code ships with a 128 GB M.2 2242 NVMe SSD fitted through a mini PCIe adapter. The four PoE++ ports share 1 Gbps through a built-in layer 2 switch on one network.

The panel also carries 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. A second full-size mini PCIe socket takes a Wi-Fi, GNSS, V2X or CAN module, and an M.2 B key socket with dual micro SIM takes a 4G LTE or 5G NR module, with five antenna holes in the case. The PoE budget is 50 W across the ports when passively cooled, or 144 W with the optional fan kit.

Power is 8 to 35 V DC on a three-pin terminal block with built-in ignition control. The NRU-52S+ runs from -25 °C to 70 °C in the 15 W mode, meets MIL-STD-810H for vibration and shock and EN 50121-3 for EMC, and Neousys lists it as EN 50155 certified for rolling stock. The NRU-52S is the Xavier NX version, and the NRU-51V+ takes four GMSL2 cameras in place of PoE++.
