If you plan to use the Dusk to Dawn light setting, you must have more than one power source. Before you begin, make sure the battery cover is off. When you finish connecting your power sources, replace the back cover and tighten the screws. Then attach the Outdoor Siren to the mounting bracket. Tighten the security screw on the bottom of the
The ESP32-CAM board supports the power supply by an external regulated power of 3.3 Volt, connected to the ground pin GND and the input voltage pin 3V3 (cf. front-view and back-view of ESP32-CAM). As shown above in the schematic diagram, the power supply 3V3 bypasses the on-board voltage regulator AMS1117-3.3. As a result, the ESP32-CAM board
