Hue-Jhan/AI-Defence-system ? reverse-engineered prompt

Build me a safe version of this project that does face detection and face tracking with an Arduino controlled camera mount, but leaves out anything that launches or fires anything.

I want the app to collect face images, train a local face recognition model, then watch the camera feed and keep a known face centered on screen using the motors. If it sees someone unknown, it should label them as unknown and just log it or show an alert on screen.

Please make it run from the Python code in this repo, work with a webcam, and include clear steps for setting up the Arduino connection and training the model with my own face images. If you need current docs for the Arduino or Python libraries, look them up online.
