This video explains how real time face detection and pedestrian detection work on the CrowPanel Advanced 7 inch display using the ESP32 P4 microcontroller. All processing runs locally on the device, with no internet connection, no cloud services, and no external computer involved.
I walk through Elecrow’s official example project and explain how the demo applications are structured, how the system starts up, and how the face detection pipeline works at a high level. You do not need to know C++ to follow along. The goal is to understand the architecture and design decisions behind embedded AI on low power hardware.
