 # What is Spatial Analysis?
 
-You can use Computer Vision Spatial Analysis to ingest streaming video from cameras, extract insights, and generate events to be used by other systems. The service detects the presence and movements of people in video. It can do things like count the number of people entering a space or measure compliance with face mask and social distancing guidelines. By processing video streams from physical spaces you can learn how people use them and maximize the space's value to your organization.

 Spatial Analysis ingests video then detects people in the video. After people are detected, the system tracks the people as they move around over time then generates events as people interact with regions of interest. All operations give insights from a single camera's field of view. 
 
 ### People counting
-This operation counts the number of people in a specific zone over time using the PersonCount operation. It generates an independent count for each frame processed without attempting to track people across frames. It can be used to estimate the number of people in a space or generate an alert when a person appears.

 ### Entrance Counting
-This feature monitors how long people stay in an area or when they enter through a doorway. This monitoring can be done using the PersonCrossingPolygon or PersonCrossingLine operations. In retail scenarios, these operations can be used to measure wait times for a checkout line or engagement at a display. In other commercial buildings, these operations could measure foot traffic in a lobby or a specific floor.
