Robotic Pan-Tilt Smart Camera
Introduction
This project is a DIY IoT security camera built around the ESP32-CAM microcontroller.
It functions as a standalone, localized smart device that streams real-time video over Wi-Fi while allowing the user to physically steer the camera’s viewing angle. The entire system is hosted on a custom web server running directly on the ESP32, meaning it requires no third-party apps and can be controlled from any smartphone or PC browser.
The primary purpose of this project is to design a localized, interactive surveillance solution that does not rely on third-party cloud subscriptions or proprietary mobile applications, while integrating mechanical actuation, high-speed data processing (video streaming) and wireless network communication into a single, low-cost microchip.
General Description
This project is a DIY, self-contained robotic security camera. Unlike commercial smart cameras, it requires no cloud subscriptions or third-party mobile apps to function.
How it Works: The ESP32-CAM microcontroller connects to your local Wi-Fi network and hosts its own internal web server. By typing the camera's IP address into any standard web browser (on a smartphone or laptop), the user accesses a custom-built control dashboard. From this webpage, the user can watch the live video stream and use on-screen sliders to physically steer the camera left, right, up, and down using two micro-servo motors.
