Gestión de video streaming mediante dispositivos iot en plataformas domóticas

Abstract

In recent years there has been a growing in the home automation industry as smart device manufacturing and smartphone dependence increases. Despite this, the problem persists in interoperability due to the lack of a standard communication protocol so the user must operate with multiple systems for the management of smart devices, which becomes a tedious task because the more difficult their management will be. In this work, a home automation system was implemented using the Home Assistant platform with a focus on integrating different types of cameras and from various manufacturers. Four types of devices were considered, first of all, there is the TAPO C200 1080p camera with PTZ function, the 1080p analog camera with its respective Hikvision brand DVR, the ESP32 CAM board with its OV2640 camera module and an Android smartphone with IP Webcam software that makes it a surveillance camera device ready for integration into Home Assistant. Based on this, different integration alternatives such as native ones were provided through the Home Assistant API for ESPHome firmware-based devices such as the ESP32 CAM board and for smartphones with IP Webcam software, also through WebRTC technology and even MotionEye for solutions where it is not possible to implement the above which ensures low latency in receiving video streams. For image capture alternatives such as using the FFMPEG command, calling the Home Assistant camera.snapshot service, and using APIs developed by camera manufacturers are provided. The system was installed on a Raspberry PI 4 with 4GB of RAM, considered to be the most powerful of its kind today to which an SSD was added to improve its performance, because the workload posed in this research cannot be efficiently developed by the traditional method of starting the operating system from a high-speed microSD card.
