IoT-Based Security System with Motion Detection

GITHUB LINK - https://github.com/DevS0ni/Python-IOT-Based-Security-Surveillance-with-Motion-Detection

Overview: Developed an Internet of Things (IoT) based security system using a Raspberry Pi 4, integrated with a camera module. The system detects motion and captures a surveillance video when motion is detected, subsequently sending a security alert email with the attached video file to the user.

TechStack Used:

• Python

Key Features:

1. Motion Detection: Implemented motion detection using a GPIO pin on the Raspberry Pi, allowing the system to identify and respond to movement in the monitored space.
2. Video Capture: Utilized the Raspberry Pi Camera module to capture a 10-second surveillance video upon detecting motion. The video is stored in H.264 format for efficient storage and processing.
3. Email Notification: Integrated email functionality to send a security alert to the user's specified email address. The email includes a descriptive subject, body text, and an attached MP4 video file of the detected motion.
4. Secure Email Transmission: Implemented secure email transmission over the SMTP protocol using the Gmail server. The system requires the user's Gmail credentials for authentication.
5. File Management: Managed file storage and deletion to optimize storage space. Old video files are removed to ensure the system operates efficiently.

Technologies Used:

• Raspberry Pi 4: Served as the main processing unit for running the security system.
• Raspberry Pi Camera Module: Captured high-quality surveillance videos in real-time.
• GPIO (General Purpose Input/Output): Used for motion detection through a connected sensor.
• SMTP (Simple Mail Transfer Protocol): Employed for sending security alert emails.
• Python Programming Language: Developed the system using Python for GPIO control, camera operation, and email handling.
• MP4Box: Utilized for converting and processing H.264 video files into MP4 format.

Setup:

• The system is set up with a Raspberry Pi 4, connected to a camera module and a motion sensor.
• The GPIO pin (pin 11) is configured to detect motion changes.
• Users need to provide their Gmail credentials and specify the recipient's email address.

Usage:

1. The system continuously monitors the space using the motion sensor.
2. When motion is detected, the Raspberry Pi Camera captures a 10-second video.
3. The video is converted to MP4 format using MP4Box for compatibility.
4. A security alert email is sent to the specified email address, including the attached video file.
5. Old video files are automatically removed for efficient storage management.

Impact: This IoT-based security system provides an affordable and effective solution for users to monitor and receive timely alerts regarding motion detection in their designated spaces. It enhances security measures with real-time video surveillance and instant email notifications.

Future Enhancements: Future enhancements may include integrating cloud storage for remote video access, implementing real-time monitoring through a web interface, and enhancing the system's scalability for broader applications.
