Finding a person of interest from the Investigation task

To quickly locate a person of interest, you can conduct an investigation in Security Center SaaS using natural language search criteria and additional smart search filters. The investigation details can then be reviewed and used to create a timeline of events, including movements, interactions, and what occurred before or after an incident.

1. Click Investigation from the vertical navigation bar.
2. In the search field, input your natural language search criteria and press Enter.
   For example:

   • "person wearing a red sweater and blue jeans"
   • "person wearing a white dress in the lobby yesterday afternoon"
   Natural language search quickly finds relevant footage without manually reviewing hours of video.
3. (Optional) To refine your search results, click the filter icon () and adjust your filters.
4. Choose a suitable thumbnail size from the Thumbnail size list to review the search results.
5. Review the results to identify your person of interest.
   1. Choose a video thumbnail to review.
      The video plays in the side pane tile with details below, such as the current video frame, clothing color filters, and so on.

      

      Reviewing thumbnails helps verify matches swiftly and prevents wasting time on unrelated clips.
   2. (Optional) Use video scrubbing to navigate the timeline quickly, scan thumbnails, and locate relevant footage:
