One of the newest smart devices is an old favorite, a camera. And smart cameras are getting smarter all the time. Some are now built with machine learning tools to help them think for themselves. Machine learning involves putting large amounts of data into a computer for processing. The computer uses an algorithm to process the data and learn from it. The machine then trains itself over time to make predictions and decisions about future actions. This technology helps cameras operate on their own by reacting to people and objects in a particular environment.
