Video tracking is a type of technology that uses cameras to follow things in a video, like people or objects. It records movements and then uses computers to analyze the recorded data and figure out where the people and objects in the video go and what they do. Video tracking can be used to help find missing people or track how people or objects move in a particular space. It's a useful way to keep tabs on what's happening in a certain area or to see how things have changed over time.
