This tech isn't new. My company uses Axis cameras and Axis has some pretty advanced video analytics software https://www.axis.com/en-us/products/analytics

It records the license plates of all cars entering and leaving the parking lots. You can associate names to faces which we do for all employees and the system automatically records when people enter and leave buildings. You can even just tell it to find all people with a blue shirt in a particular camera in a time window. It can automatically detect people shouting.
