Project Details
How It Works
How It WorksThe ESP32-CAM captures video frames continuously. The CameraWebServer example code compares consecutive frames to detect changes (motion). When significant changes are detected above a threshold, it triggers actions like capturing a photo, starting video streaming, or sending alerts. The motion detection algorithm runs directly on the ESP32-CAM's processor, making it a self-contained system that doesn't require external processing.
Prerequisites
Basic knowledge of Arduino IDE and ESP32 programming. Familiarity with camera concepts and Wi-Fi networking. Understanding of how to upload code to microcontrollers.
What You'll Learn
What You'll LearnLearn to detect motion by comparing video frames
