Telematics is a way of tracking and collecting information about an object, vehicle, or animal. It uses sensors and computers that communicate over cellular networks to send data back to a central system. This data can then be used to track the object, help keep it safe, and improve its performance. For example, a car with telematics can have its location monitored, its speed and engine performance checked, and if it gets into an accident, a signal can be sent to emergency services.
