The ESP32-CAM is a small form-factor camera module based on the ESP32-S Wi-Fi and Bluetooth chip and integrates an OV2640 2 Megapixel camera. This module is an ideal solution for building low-cost, connected smart applications such as wireless video surveillance, remote monitoring, QR code recognition, and motion detection. With built-in Wi-Fi, you can stream video directly to your network or the internet. The module also features a microSD card slot for local storage of images and videos.
