Esp32-cam-motion-detection Review

: Requires connecting a PIR sensor (e.g., HC-SR501) to a GPIO pin.

: Uses libraries like the Eloquent Arduino library to compare consecutive frames for pixel changes.

: Includes a built-in MicroSD card slot for local storage of triggered captures. esp32-cam-motion-detection

: No external hardware needed; allows for custom "detection zones" and sensitivity levels.

: 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 : Requires connecting a PIR sensor (e

: Typically comes with the OV2640, supporting up to 1600x1200 resolution.

: Supports RTSP and SIP for live streaming to external servers. Implementation Guide Computer vision – Eloquent Arduino Blog : No external hardware needed; allows for custom

: Expect around 25 fps at VGA (640x480) or ~12 fps at HD (1280x720).
