: Low power consumption (ideal for battery operation) and high reliability with fewer false positives.
: Uses libraries like the Eloquent Arduino library to compare consecutive frames for pixel changes.
: Requires connecting a PIR sensor (e.g., HC-SR501) to a GPIO pin. esp32-cam-motion-detection
: 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. : Low power consumption (ideal for battery operation)
: When the sensor detects heat-based motion, it triggers the ESP32-CAM to "wake up" and capture an image. Video Motion Detection (Software-Based):
: Expect around 25 fps at VGA (640x480) or ~12 fps at HD (1280x720). : The camera continuously captures frames at low
: Supports RTSP and SIP for live streaming to external servers. Implementation Guide Computer vision – Eloquent Arduino Blog
