The purpose of installing a video surveillance system is usually to view places that are important to control from the point of view of the safety of material values (parking lots, supermarket shelves, warehouses, etc.), control of entry into an object (checkpoints, fences, doors, gates, etc.) ), tracking the movement of objects (stations, offices, enterprises, etc.).
In many ways, these systems replace humans, including the ability to predict. They are able to identify the queue at the checkout, analyze the movement of flows of people or vehicles, find and fix the numbers of the latter, monitor certain areas and identify suspicious activity on them.
