https://www.youtube.com/watch?v=Ul0h5Maeoeg In this video I run you through the process of me developing a fully-equipped ESP32-CAM-based Solar-powered WiFi Security (Surveillance) Camera from the ground up. Overcoming a handful of obstacles in the way along the journey of building the unit, after 3 months, I am proud to announce that I have succeeded! Even though the camera can have more improvements done to really get the most out of it (Hardware-wise and with remote access features), it still has turned out to be a capable DIY security camera that can already do so much. https://github.com/s60sc/ESP32-CAM_MJPEG2SD and diagram SP32 Camera motion capture application to record JPEGs to SD card as AVI files and stream to browser as MJPEG. If a microphone is installed then a WAV file is also created. Files can be uploaded via FTP or downloaded to browser.

https://github.com/fellowgeek/esp32-relay-board This WeMos D1 Mini ESP32 Relay Board features 6 channels and is compatible with both 24V AC and 5V DC power sources. Specifically designed as a seamless replacement for sprinkler controller systems, this board offers straightforward configurability using jumpers. These jumpers provide the flexibility to set it up as either standalone relays or common input relays, making it an adaptable solution for various applications.
