How the ESP32-S3 Camera Module Works
The ESP32-S3 CAM board operates on a simple yet powerful principle that enables advanced image processing and AI capabilities:
- The OV2640 camera captures images/video
- Data is processed by the ESP32-S3 MCU
- Images can be:
- Streamed over Wi-Fi
- Stored on SD card
- Processed locally for AI tasks
- Results (face detection, motion detection, etc.) can trigger actions
The higher PSRAM allows smoother streaming and handling of larger image buffers, making it perfect for real-time video applications.
