Diseño de una red de supervisión y control con transmisión de audio y video en alta definición para la ESPOCH.

Abstract

This research is intended to design a watchfulness high-definition audio and video network interface supported by the Internet Protocols IP for the Escuela Superior Politeécnica of Chimborazo in order to provide of watchfulness system for controlling and monitoring the security of its settings such as parkinng lots, gates, and green areas mainly. In the aim of this research prposal, the technical and aconomic feasbibility study was carried aut at first, accounting for an acceptability of 80% in regarding watchfulness system converture and quantitative and qualitative scales (0 - 4) for measuring the effectiveness of the watchfulness system devices such: video-cameras, multimedia network recorders, communications device setting and fibre-optic since the network bandwidth favors the video-audio stream for its high fidelity and speed resolution in the data streaming which accounting for 90% of efficiency, contrasting to 65% of the Ethernet cable resoluions, on the other hand, the video network recorder (NVR) and the camera types chosen for this study accomplish the standards in regarding the audio-video high resolution of network recorder (NVR) accounting for 80% and 85% of effectiveness in the case of security-cameras bullet panning, tilt, zoom (PTZ) and tame respectively. This research was carried out by implementing a ptoyotype of the study proporsal for its evaluation, based on the image quality, the system functioning and network bandwidth performance of current watchfulness system reaches 25.75% whereas the performance of the study proporsal system is improved in 87.5%. The star topology extended was used in order to profit the fibre-optic cabling existing in the institution to reduce costs leading to the design scalabilty and effectiveness. The total of the system security-cameras purposed by the study proporsal consists of 40 security-cameras which are both fixed and domo cameras placed in the vulnerable areas. The study resutls reveals that the watchfulness system of this study proporsal affers a flexibility to the equipment adaptability in regarding the best technological performance as well as the best costs, that is, the cost of the study proporsal design and implementatiion accounts for 80% in regarding the institution budget for watchfulness. Therefore, it is advisable to broaden up the eatchfulness system from this study proporsal design in order to diminish the delinquecy rates into institution settings.
