In Axxon One metadata can be obtained in two ways:

1. By analyzing video streams stream on Server by detection tools.
2. By receiving metadata from camera built-in analytics (see Embedded Detection Tools). 

...

The following tools are used for server-side analysis and metadata generation:

1. Object Tracker.

2. Neural Tracker.

   Info
   title Note
   Object tracker and Neural Tracker generate metadata containing the following information about moving objects in FOV: object type, position, size and color, motion speed and direction, etc.

   
   

3. VMD.

   Info
   title Note
   VMD generates less accurate data. It does not detect object type and color.

   
   

4. Face detection tools.

   Info
   title Note
   Face detection metadata contains face bounding boxes and their positions, as well as face vectors.

   
   

5. Automatic Number Plate Recognition (LPR/ANPR) tools.

   Info
   title Note
   ANPR metadata contains license plate bounding boxes and their positions, as well as vehicle registration numbers.

   
   

6. Pose detection.

   Info
   title Note
   Metadata from pose detection tools contains information on positions and pose (skeleton) of all people in FOV.

   
   

7. Equipment detection tool (PPE)

   Info
   title Note
   Equipment detection metadata contains information about the position of all the people in FOV.
