Milesight UR75 Industrial 5G PoE Router with Wi-Fi 6 and GPS (POE Version UR75-504AE-P-W2)

Milesight UR75-504AE-P-W2 Industrial 5G Router with PoE PSE

The Milesight UR75-504AE-P-W2 is an industrial 5G router from the Ultra Series with 4-port 802.3 af/at Power over Ethernet (PoE PSE). It is the same high-performance platform as the UR75-504AE-W2, with the addition of PoE output capability on all four LAN ports. Each port delivers up to 30W, with a combined PoE budget of 60W. A 48V DC power adapter is included.

The UR75-504AE-P-W2 lets a single router provide both 5G cellular backhaul and power to connected PoE devices, removing the need for separate PoE injectors or switches at remote or space-constrained sites. It supports 5G Sub-6 GHz in NSA and SA modes with automatic fallback to 4G LTE and WCDMA. The quad-core ARM Cortex-A55 processor, dual SIM failover, Wi-Fi 6, RS232/RS485 serial, integrated GPS, and DIN-rail-mountable IP30 enclosure complete the platform.

Applications

5G-Connected CCTV and IP Camera Systems

The UR75-504AE-P-W2 provides 5G backhaul and powers up to four PoE IP cameras from a single device. This eliminates the need for a separate PoE switch and reduces the hardware count at each camera site. The 60W PoE budget covers four standard 802.3 af cameras or a mix of 802.3 at devices. Dual SIM failover ensures the video feed stays online if a mobile network goes down.

Wireless Access Point Deployment over 5G

Where wired internet is unavailable, the UR75-504AE-P-W2 delivers 5G backhaul and simultaneously powers PoE wireless access points over its LAN ports. This is a practical solution for temporary event sites, construction compounds, and rural buildings where running a wired internet connection is not feasible. Wi-Fi 6 on the router itself adds a second wireless layer for devices that connect directly.

Industrial Automation with PoE Sensors and Displays

Industrial PoE devices – including managed industrial switches, barcode scanners, HMI panels, and IP intercoms – can be powered and connected via the UR75’s LAN ports. RS232 and RS485 serial ports handle legacy Modbus devices in the same enclosure. This makes the UR75-504AE-P-W2 a consolidation point for mixed IP and serial device networks at remote industrial sites.

Smart Building and Retail IoT

Smart building controllers, digital signage players, PoE occupancy sensors, and access control readers all draw power from PoE. The UR75-504AE-P-W2 provides 5G backhaul and PoE power from a DIN-rail-mounted device inside a building services cabinet. Integrated GNSS records the installation location for asset management purposes.

Temporary and Pop-Up Site Connectivity

Construction sites, temporary offices, and event venues often need rapid network deployment without permanent infrastructure. The UR75-504AE-P-W2 provides 5G internet via a SIM card and powers PoE phones, access points, or entry system hardware from a single unit on a DIN rail or shelf. When the site closes, the router moves to the next location.

Remote CCTV and Monitoring for Utilities

Water treatment sites, substations, and pipeline monitoring points often need IP cameras and sensors at locations without mains cabling. The UR75-504AE-P-W2 powers PoE cameras over its LAN ports while the RS485 port connects to RTUs or meters. 5G backhaul with dual SIM redundancy keeps the link reliable. A fixed IP SIM card provides a stable address for VPN tunnel termination and remote access.

Frequently Asked Questions

What is PoE PSE and how does it work on the UR75-504AE-P-W2?

PSE stands for Power Sourcing Equipment – the device that sends power over the Ethernet cable. On the UR75-504AE-P-W2, all four LAN ports can act as PoE PSE ports, supplying 802.3 af (up to 15.4W per port) or 802.3 at (up to 30W per port) power to connected devices. The PoE budget across all four ports combined is 60W. The connected device must be a PoE-compatible PD (Powered Device), such as an IP camera, wireless access point, or VoIP phone. No PoE injector or separate PoE switch is needed.

Does the UR75-504AE-P-W2 require a specific power supply for PoE to work?

Yes. PoE output is only active when the router is powered from a 48V DC supply via the terminal block connector. The included power adapter provides 48V. If the router is powered at a lower voltage (for example, via the USB Type-C port at 5V), it operates as a standard router but PoE output on the LAN ports will not function. The 9-48 VDC input range means the router works in most vehicle and cabinet power environments, but 48V is specifically required for PoE operation.

How many PoE devices can the UR75-504AE-P-W2 power at once?

The router has four PoE LAN ports with a 60W total PoE budget. In practice, this means four standard 802.3 af devices at up to 15.4W each, or a mix of 802.3 af and 802.3 at devices where the combined draw does not exceed 60W. For example, two 802.3 at PoE cameras at 25W each would use 50W of the 60W budget, leaving 10W for a third low-power device.

Does the UR75-504AE-P-W2 support dual SIM?

Yes. The router has two Mini SIM-2FF slots. It supports automatic failover and failback between SIM1, SIM2, and alternative WAN connections including Ethernet WAN and Wi-Fi client mode. When the primary SIM loses connectivity, the router switches to the backup SIM without manual intervention. For deployments where a fixed IP address is required for remote access or VPN, a fixed IP SIM card is the correct choice.

Can I manage multiple UR75 routers centrally?

Yes. Milesight DeviceHub provides centralised configuration, firmware updates, real-time monitoring, and reporting across fleets of UR75 devices. It supports bulk configuration pushes and remote troubleshooting. MilesightVPN provides VPN tunnel management alongside DeviceHub. Both platforms are cloud-based and accessible without requiring a fixed IP SIM, though a fixed IP SIM simplifies direct device-to-device VPN connections.

What is the operating temperature range of the UR75?

The UR75-504AE-P-W2 operates from -40°C to +70°C. Storage temperature range is -40°C to +85°C. Humidity tolerance is 0% to 95% non-condensing at 25°C. The IP30 metal enclosure is suitable for DIN rail installation in industrial cabinets and outdoor enclosures. PoE output power adds a small thermal load; ensure adequate ventilation in enclosed cabinet installations.
