Forensic Search in Archive Subsystem

The Forensic Search in archive subsystem is a set of tools for searching video recordings in the archive by using video image metadata. The video image metadata include information on the trajectories of object motion in the video camera’s field of view, object color, etc. (depending on the algorithms being executed on the video camera).

In the Axxon Next software package, the functions of the Forensic Search in archive subsystem are enabled by the object trajectory database (which is created when the software package is installed). These functions can be accessed through the video surveillance monitor.

Thanks to Axxon Next's Forensic Search in archive subsystem, the user can utilize the following functions:

1. Selection of a video camera from which it is necessary to record video image metadata to the object trajectory database.
2. One-time searching by one of the criteria related to the video camera’s field of view:
   
   1. Motion in a specific area
   2. Crossing of a virtual line
   3. Loitering of an object in a specific area
   4. Simultaneous presence of a large number of objects in a specific area
   5. Motion from one area to another
3. Searching by the following parameters (optional):
   1. Minimum size of an object
   2. Maximum size of an object
   3.  An object’s color
   4.  Minimum speed of an object
   5. Maximum object speed
   6. Direction of an object’s motion
   7. Maximum number of objects in an area
   8.  Length of time an object remains in an area
