Parking Lot CCTV With Space Detection

Urban areas waste a ridiculous amount of time and fuel on “parking Hunting” because most parking lots still run on manual checks or stale signboards. This project proposes an IoT- based Parking Lot CCTV with Space Detection System that provides real-time parking slot availability along with live video surveillance for verification and safety. An ESP32 acts as the main controller and connects four IR sensors, each mapped to a single parking slot, to detect vehicle presence instantly. Slot status is pushed continuously to Firebase Realtime Database, enabling live synchronization between the hardware and software layers. For surveillance, an ESP32-CAM streams real-time parking footage through a lightweight HTML web interface, accessible via the device IP show in the Arduino IDE serial monitor. A Java/XML Android application reads the Firebase updates and display slot availability in a clean user interface, helping drivers decide before entering the lot. Supporting modules like a dot matrix display provide guidance/welcome messages, while a buzzer gives entry/exit alerts, improving user interaction. Built on a zero PCB, the design remains compact, low-cost, and scalable making it suitable for smart parking deployment in smart city environments.
