The Axiomtek UST520 Series is a rugged, fanless in-vehicle embedded system designed for intelligent surveillance, mobile NVR, and edge AI applications in buses, lorries, public transportation, and specialised fleets. Powered by socketed 14th/13th/12th Gen Intel Core i9/i7/i5/i3 or Celeron processors with the Intel R680E chipset, it delivers desktop-class performance for video analytics, ANPR, passenger counting and real-time monitoring at the edge.

Engineered for harsh transportation environments, the UST520 operates reliably from -40 °C to +70 °C and supports 9V to 60V DC input with smart ignition for safe power-up and shutdown linked to the vehicle’s ignition status. Comprehensive power protection (over-current, over-/under-voltage and reverse polarity) and E-Mark/R118 certifications make it ideal for road and rail deployments.

For high-density IP camera installations, the UST520 offers up to 16x 2.5GbE PoE/PoE+ ports via RJ-45 or M12 X-code connectors with a 120 W PoE budget, simplifying cabling and powering cameras directly from the system. Flexible storage with 2 or 4 swappable 2.5" SATA bays and RAID support is perfect for long-duration video recording. At the same time, M.2 and mini-PCIe expansion enable 5G/LTE, Wi-Fi, GPS and additional I/O to support mobile connectivity and fleet-wide data backhaul.

Housed in an IP40 aluminium extrusion and heavy-duty steel chassis with proven vibration endurance, the UST520 can be wall-mounted in tight cabins and equipment racks. Extensive I/O, including HDMI, VGA, USB 3.2, isolated digital I/O and dual CANBus, simplifies integration with existing vehicle systems, sensors and HMIs. This makes the UST520 Series a powerful, future-proof platform for intelligent transportation systems, connected fleets and on-board surveillance where reliability, performance and connectivity are critical.
