Finding a person of interest from the Investigation task

To quickly find a person of interest, you can perform an investigation in Security Center SaaS using natural language search criteria and additional intelligent search filters. The investigation information can then be reviewed and used to build a timeline of events including movements, interactions, and what happened before or after an incident.

1. From the vertical navigation bar, click Investigation.
2. In the search field, enter 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 selects relevant footage without manually scanning hours of video.
3. (Optional) To refine your search results, click the filter icon () and set your filters.
4. To sort the results, click Sort by and select an option:

   Relevance

   Displays 500 most relevant results in order of relevance.

   Most recent

   Displays 500 most relevant results in reverse chronological order.

5. From the Thumbnail size list, select an appropriate thumbnail size for reviewing the search results.
6. Review the results to find your person of interest.
   1. Select 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.
