Teltonika FMC225 — IP67 Waterproof 4G LTE Cat 1 GPS Tracker with Dual SIM and RS232/RS485

The Teltonika FMC225 is the IP67 waterproof version of the FMC125 — combining all the dual SIM, RS232/RS485, 1-Wire and Bluetooth professional capability of the FMC125 with a fully sealed IP67 enclosure for agriculture, construction, mining and any harsh environment fleet application. Built on the proven Teltonika FMC platform, the FMC225 retains every feature of the FMC125 and adds full dust and water resistance — allowing it to be mounted inside or outside any vehicle without concern about high-pressure water, mud or extreme dust.

The FMC225 is also one of the compatible trackers for Teltonika's DualCam dashcam solution — combining IP67 durability with dual-camera video recording for comprehensive driver safety and incident evidence across harsh environment fleet operations. Combined with impulse input for highly accurate fuel flow meter monitoring, dual SIM for international roaming cost reduction and RS232/RS485 for professional sensor connectivity, the FMC225 is the definitive waterproof professional 4G tracker for demanding fleet applications.

As an official Teltonika distributor in the UK, Tracking Hardware UK ships the FMC225 directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.
