ES825 is a 4G (Cat-M1&NB-IOT) mini waterproof GPS tracker for animals. This device has special algorithms which can make the device keep working for a long time without charging, which solves the trouble of frequent charging. It normally reported data once a day and it has pseudo-real time tracking function so it can be quickly set to quick-reporting mode when the animal is lost. If it just one day one report and the function of pseudo-real time tracking is off, the device can keep working for longer time without charging. ES825 reports location information via HTTP, TCP, UDP or SMS with configurable intervals. ES825 has three mode localization with GPS+WIFI+LBS and it improves the location accuracy.
