ES421 is an LTE (Cat.1) waterproof GPS asset tracker with 7,800mAh large battery. Thanks to its embedded magnets, ES421 can be easily installed to many objects with iron surface. Light sensor is used for detecting the drop or detachment of the device from the asset and a tamper message will be sent if it happens. It is carefully designed for long standby time purpose. Vibration mode is very useful for the applications in which the location information is unnecessary when it is stationary to save data communication and power consumption.
