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

To extract get metadata from video, you have to de-compress and analyze the video stream, which increases the load on the Server's workload, thus limiting the number of available camera channels. |

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.
VMD.
Info title Note VMD generates less accurate data. It does not detect object type and color.
Info title Note Face detection metadata contains face bounding boxes and their positions, as well as face vectors.
Automatic Number License Plate Recognition (LPR/ANPR) and Vehicle Recognition detection tools.
Info title Note ANPR metadata contains license plate bounding boxes and their positions, as well as vehicle registration numbers.
Info title Note Metadata from pose detection tools contains information on positions and pose (skeleton) of all people in FOV.
Personal protective equipment detection tools.
Info title Note Equipment detection metadata contains information about the position of all the people in FOV.
- Barcode Detection.
Info title Note Metadata from the Barcode Detection contains information about the contents of all barcodes in the frame.
The metadata is used for the following system options:

If a camera uses several sources of metadata, the required source is selected automatically, except for MomentQuest. To perform face/license number searches, only metadata from corresponding detection tools is used. |
By default, metadata is stored as files in the object trajectory tracks database in the local Server directory that was selected when installing Axxon One (see Installation) in the vmda_db\VMDA_DB.0\vmda_schema subfolder.
