: The camera continuously captures frames at low resolution; if the "motion ratio" exceeds a set threshold, it triggers an action (like saving a high-res image to the SD card). Core Technical Specifications
: Typically comes with the OV2640, supporting up to 1600x1200 resolution. esp32-cam-motion-detection
The is a powerful, low-cost microcontroller that combines Wi-Fi/Bluetooth capabilities with an integrated camera module. For motion detection, you can choose between a hardware-based approach using an external PIR sensor or a software-based approach using image processing. Motion Detection Methods PIR Sensor (Hardware-Based): : The camera continuously captures frames at low
: No external hardware needed; allows for custom "detection zones" and sensitivity levels. HC-SR501) to a GPIO pin.
: Requires connecting a PIR sensor (e.g., HC-SR501) to a GPIO pin.
