As we have said, data is the fuel that powers artificial intelligence. And that data comes from sensors. Sensor technology has been around many years. For example, in the security industry motion detectors and door and glass-break sensors are commonplace. They are basic devices that sense an event and send an alarm that then has to be interpreted by humans. Today’s sensors are much smarter. Using AI, they can not only detect an activity, they can learn to put that activity into context and act upon it.
