LTE Cat M1/NB1 Advanced Asset Tracker
Product Description: 

GL500 series (LTE) includes three waterproof GNSS trackers that feature an up to 7 years standby time powered by internal batteries. The series is ideal for a range of tracking applications that require real-time monitoring on temperature and light. GL500 series (LTE) supports LTE Cat M1/NB1 network on multiple bands for operation in America, Europe, and Oceania with a fallback to GPRS.




  • Rapid and covert installation – no wiring, no external antennas
  • 7-year standby time with internal battery
  • Thumb-sized button with vibration feedback allowing confirmed emergency alert or instant geo-fence setting
  • Motion detection based on internal 3-axis accelerometer
  • Automatic mode switching – power saving mode for long standby time and continuous mode for emergency tracking

  • Temperature monitoring based on internal temperature sensor
  • Tamper detection based on internal light sensor
  • Waterproof IP67 compliant

  • Optional magnetic mounting
