- difficulty in detecting

Tracking a person's location - GPS tracking
GPS trackers track a person's location 24 hours a day. And are able to perform many additional features. On the map, the route is shown as a solid line. You can receive a signal using mobile phone or any other device with an internet connection.

The system works according to this principle: throughout the entire time it is in sleep mode to save energy, but as soon as the need arises, it signals the current location. The life of the beacon in this mode can be 8-10 months. The most advanced GPS beacons can perform a listening function.
Fine tuning helps to set the restriction zone. If a person leaves it, the owner of the device will receive an SMS or e-mail. The message will contain information with the coordinates of the beacon.
