Desenvolvimento de um sistema integrado e customizado de monitoramento de um circuito de televisão fechado distribuído para a ALTEL

Abstract

The following is a report on the activities carried out during the professional internship period at ALTEL Global Communication Solutions, with the main objective of describing the process of developing a monitoring system for a distributed CCTV system for an organization that is a client of ALTEL. The organization's current CCTV monitoring system faces several limitations, such as the difficulty in remotely accessing live video transmissions, reliance on outdated and discontinued technology, the impossibility of multiple user sessions and simultaneous transmission. The project aims to develop a more secure and modern CCTV monitoring system that is multi-platform, including Android, iOS, and Web, scalable, as it allows multiple user sessions and simultaneous transmission, and security-oriented, applying best development practices and employing secure protocols for communication. The proposed system was built based on client-server architecture using the TypeScript programming language, and using JavaScript UI libraries, such as React and React native, for the client applications. The development methodology followed an incremental approach and bibliographic research was conducted to acquire knowledge on relevant topics, such as communication protocols in security devices, video transmission protocols and good practices for secure code. The proposed system is intended to resolve the limitations of the existing monitoring system and provide a more modern, secure, and flexible solution for accessing live images from the CCTV system
