1. Introduction
1.1 Purpose of Document.
This project aims to develop a comprehensive device monitoring and control system using
a Raspberry Pi as a central platform. The system will be designed to provide surveillance
and image capture capabilities when changes in the viewing range are observed, as well
as the creation of high quality remote control software for specific devices. We will use
open source hardware and software to achieve an efficient and affordable solution. This
document describes the scope, objectives and goal of the new system. It also describes
the non-functional requirements and functional requirements with use cases.
Additionally, it aims to drive the design and deployment of the applications related to the
system.

1.3 Background
Surveillance and device control have gained significant importance in today's society due
to the growing need for security and automation in various environments such as homes,
offices, warehouses and industrial areas. These systems allow users to monitor, manage
and control devices and cameras remotely, providing convenience, efficiency and, most
importantly, security. Historically, surveillance and control systems used to be expensive
and limited to commercial and government facilities. These systems often required
complex infrastructure and dedicated security personnel. In addition, commercial
solutions tended to be expensive, limiting their adoption in home and small business
environments.
Raspberry Pi, a low-cost, high-performance computing platform, has emerged as a
revolutionary solution to address these limitations. The Raspberry Pi is accessible both in
terms of cost and ease of use, making it an ideal choice for surveillance and control
projects, as well as advances in open-source software and specialized hardware
development have enabled technology enthusiasts and professionals to create highly
customized and efficient surveillance and control systems using Raspberry Pi. Platforms
such as Raspbian (Raspberry Pi OS) and tools such as MotionEye, ZoneMinder and
Shinobi offer advanced surveillance capabilities.
In an increasingly connected world, security and automation are imperative. Monitoring
and control systems not only provide greater security for assets and people, but also
enable users to automate tasks and devices, improving efficiency and quality of life.
This project seeks to leverage the versatility of the Raspberry Pi and the availability of
open-source surveillance and control software to develop a complete and affordable
system that provides high quality surveillance and remote-control capabilities. The
system will be designed to be accessible to home users, small businesses and technology
enthusiasts, providing an affordable and customizable solution for their security and
automation needs.
1.4 Project Scope
Develop a surveillance and control system using Raspberry Pi, including Raspberry Pi
configuration, high quality surveillance with motion detection, custom software for
camera management, possibility to maintain remote control from other devices, secure
remote access and detailed system documentation.
