ES321 is a 3G (W-CDMA) waterproof GPS asset tracker. Carefully designed for long battery life, it can last 5 years (one report per day) with 7800mAh battery. Embedded with magnets, it can easily attach to vehicle, trailer, container for asset tracking. It will wake up for reporting location information when it senses moving of the asset and power down itself when it is stationary. It supports TCP/UDP and HTTP for reporting location information. ES321 will automatically switch to cell-ID based location reporting whenever GPS is not available.
