Implementación de un Sistema de Videovigilancia IP y Alarma Integrado, Utilizando Software Libre Sobre Raspberry PI, para la Seguridad en el Sector de las MIPYMES.

Abstract

This Research work was carried out to implement a prototype of Integrated System of video-surveillance IP (internet protocol) and alarm by the means of free software about Raspberry Pi for security in Micro, Small and Medium – sized Enterprises (SMEs) in the Instituto de Nivelación y Preparación de Exámenes (IPREX) in order to alert presence of intruders preventing risking the lives of people. Deductive method was used to design and identify the main characteristics of the system of video-surveillance IP and tradicional alarms like: capture of images, motion detection, alert of presence of intruders and possibility of local and/or remote access: to select free software tools compatibles with computer of reduced plate video motion as controller and manager of cameras, module chan_mobile of Call Center Asterisk to connect Bluetooth devices and adapt the system to institution needs through creation of command interpreters files (scripts). The system is compatible with Windows and Linux and accessible from a local or remote network, it has four webcams which capture 2 images per second at detecting motion of 22 KB with resolution 320 x 240 pixels; maximum long of cable connected to camera is 20 meters. System of video- surveillance IP is on from Mondays to Fridays from 7:55 am to 7:29 pm, at 7:30 the system generates an alert by the means of a siren audio and calling the user. It reaches to alternate its functionality in the same structure, according to user needs and connecting to mobile and internet platforms for its manager, generating an immediate answer when there is something irregular.
