Quick Overview

4G, GSM, GPS tracker with up to 3 years on one charge.

The JM-LL01 is an LTE asset tracker with ultra-long standby time. Depending on reporting frequency, its low consumption internal battery can provide up to 3 years of working time on a single charge.

Strong Magnetic Mount

The JM-LL01's strong magnetic base allows for effortless installation onto any metal surface, and a light sensor will be triggered and an alert sent once detachment occurs, helping users to feel totally assured that their assets are under constant protection.  An included metal plate allows magnetic installation to non-magnetic surfaces and cable tie points are also included.
