ApoorvGit/Video-Surveillance-and-tracking-system — reverse-engineered prompt

Build me a Python desktop app for a smart CCTV surveillance system using facial recognition. I want to connect multiple camera feeds, recognize known faces, and show where a person was last seen inside a building or premise.

The app should let me keep a simple record of people entering the premises using their face instead of ID cards or manual entry. It should store basic face data and entry records locally, then allow tracking a selected person across available camera feeds. A simple GUI is fine, something practical rather than fancy.

Please use OpenCV and face recognition style logic, and keep the project easy to run from a main Python file. Include sample database handling and clear places where camera sources can be configured. If something needs setup, add simple instructions so a beginner can run it. Look up current docs online if needed.
