Finding a person of interest from the Investigation task

To quickly find a person of interest, perform an investigation in Security Center SaaS using natural language search and intelligent search filters. Review the investigation details 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.
