Abstract:
In a technological era marked by rapid obsolescence, this project focused on
transforming retired smartphones into functional Closed-Circuit Television (CCTV) cameras,
the initiative taps into the untapped potential within these devices, leveraging built-in cameras,
sensors, and connectivity features. The project's fundamental goal is twofold: mitigating
electronic waste and offering a cost-effective, sustainable alternative for bolstering security.
The application empowers users to convert old smartphones into active CCTV cameras,
creating a comprehensive and easily manageable surveillance network. Beyond individual
security, the initiative aims for broader societal impacts, including reduced electronic waste,
heightened accessibility to sustainable security, and fostering a collective commitment to
environmental stewardship.
The project addresses the shortened smartphone lifecycle prevalent in today's techdriven society, driven by factors like rapid advancements and battery degradation. It seeks to
alleviate associated issues, such as electronic waste, by providing a solution that extends
smartphone usability and aligns with environmentally conscious practices. The application's
objectives include creating an easily installable CCTV system, enhancing security for homes
and small businesses, and eliminating the need for additional expenditures on conventional
CCTV systems. Implemented using Agile methodology, the project ensures flexibility,
adaptability, and customer satisfaction in the development process, leading to a future-rich
application with real-time streaming, multiple connections, recording capabilities, QR code
scanning, and speaker access.
The project's scope covers features such as real-time recordings, simultaneous
monitoring of multiple CCTV cameras, saving recordings to the user's smartphone memory,
and QR scan functionality. However, limitations include the inability to control camera
movement, a constant requirement for a power source, and variations in camera quality based
on individual smartphone specifications. In the final project outline, five chapters detail the
background, literature review, system analysis, system design, and a conclusion with future
work. The comprehensive approach to repurposing legacy smartphones not only addresses
current technological challenges but paves the way for sustainable, accessible, and innovative
security solutions.
