The Amcrest GPS Tracker offers real-time tracking with up to 5-second updates through Windows and MAC desktop web-access (Chrome, Safari, Edge, Firefox) or the Amcrest GPS smartphone app (iOS/Android). The intuitive user interface allows you to monitor activity easily, manage alerts, and generate custom reports. Create links and share them with the family to keep track of children, seniors, and assets. Create custom geo-fencing zones that alert you anytime the GPS tracker enters or exits a zone.
