GL521MG – Rechargeable IP67 LTE Asset Tracker - Queclink
Long-term Asset Tracking and Global Connectivity
The GL521MG is a robust IoT tracker, leveraging LTE Cat M1 / NB-IoT connectivity (with 2G fallback) to ensure reliable data transmission, regardless of country or network. Thanks to its extensive connectivity and extended standby battery life, it is ideal for long-term asset tracking, such as trailers, logistics equipment, containers, or static assets.
Rechargeable, Waterproof, and Flexible
Unlike fixed-battery trackers, the GL521MG offers wireless (Qi) charging, simplifying maintenance while maintaining a robust and waterproof (IP67 standard) casing. Its compact size and modular attachment system (clip, magnet, discreet mounting) allow for easy and discreet integration on any type of asset, perfect for logistics, fleet management, or equipment monitoring.
Precise Tracking and Comprehensive Environmental Monitoring
Equipped with a high-performance GNSS receiver (position < ~2.5 m), the GL521MG ensures reliable and precise geographical tracking. It also integrates internal sensors (temperature, light), a 3-axis accelerometer, and offers advanced features such as motion detection, environmental monitoring, or tamper detection, essential functionalities for cold chains, sensitive goods transport, or the protection of valuable assets.
