: Supports RTSP and SIP for live streaming to external servers. Implementation Guide Computer vision – Eloquent Arduino Blog

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

: No external hardware needed; allows for custom "detection zones" and sensitivity levels. esp32-cam-motion-detection

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

: Includes a built-in MicroSD card slot for local storage of triggered captures. : Supports RTSP and SIP for live streaming

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 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

: When the sensor detects heat-based motion, it triggers the ESP32-CAM to "wake up" and capture an image. Video Motion Detection (Software-Based):
