Forensic Search for Fragments
Forensic Search lets you search for moments in the archive using the following criteria:
1. Motion in a specific area
2. Crossing of a virtual line by an object’s trajectory
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
Forensic Search steps
Forensic Search is carried out in several steps:
1. Set the search interval (see Setting a search interval ).
2. Select a search criterion.
Note
In the current version of EyStream, you can search only by one criterion at
a time.
3. Edit the visual element necessary to carry out the search based on the selected criterion.
4. Configure the criterion parameters.
5. Start the search and view the results.
Steps 2 and 3 are used to refine the search query. These steps can be skipped, in which case the
search will be carried out using the default parameters or previously set parameters (see the note
below). For example, in the first case, using the Motion criterion, a search will be made for any
motion in the central area of the frame with a width and height equal to 40% of the width and
height of the frame, respectively (see the section titled Area ), regardless of the size of the moving
object, its color, or the direction and speed of its motion.
Note
The visual element necessary for searching the selected criterion and the
parameters of the criterion are saved if the user switches to another search
criterion, exits forensic search mode, or even restarts EyStream.
Selecting a search criterion
To select a criterion for Forensic Search, you can use one of five expanding tabs:
Note
These tabs are displayed on the Forensic Search tab in the search control
panel.
1. – Motion in an area
2.
– Object trajectory crossing a virtual line
