If your GPS tracker comes with the ability to set up geofences or 'safe zones', this means that you will be able to define a specific area that if tracker leaves or enters, you (or a monitoring team) will be notified. How you do this changes depending on device but it is commonly done through an accompanying app that you have on your phone. Other methods to do this are by talking to the provider when you set up or on a website on the computer.
