With the emergence of new concepts like smart hospitals, video surveillance cameras should be introduced in each room of the hospital for the purpose of safety and security. These surveillance cameras can also be used to provide assistance to patients and hospital staff. In particular, a real-time fall of a patient can be detected with the help of these cameras and accordingly, assistance can be provided to them. Different models have already been developed by researchers to detect a human fall using a camera. This paper proposes a vision based deep learning model to detect a human fall. Along with this model, two mathematical based models have also been proposed which uses pre-trained YOLO FCNN and Faster R-CNN architecture to detect the human fall. At the end of this paper, a comparison study has been done on these models to specify which method provides the most accurate results

The main objective of this article is to make a psychosocial analysis of forms of government in their relations with video surveillance, especially regarding the effects produced in terms of subjectivity, a dimension of the use of technologies in city governance that urban e-planning ought not to ignore. This will contribute to the body of knowledge surrounding contemporary video surveillance in its current practices in Rio de Janeiro, and also help researchers to understand how existing policies that regulate this phenomenon are appropriated by people who live in this city. The presence of surveillance cameras as an element of everyday life in urban centers has dramatically increased in recent years. As important actants in the practice of government, these security dispositifs are articulating heterogeneous elements and “performing” very specific realities. However, particularly in Brazil, studies on video surveillance are still limited. Therefore, it is worth investigating which government performances in Brazil have been produced from the relationships established by surveillance cameras, and how those practices and knowledges are produced as effects of these same relationships. Likewise, by understanding that each subject responds differently to such actants, the authors intend to bring out the different versions that compose, specifically, this techno-scientific controversy and its resonances in the daily lives of common citizens. This article follows ideas proposed by Actor-Network Theory (ANT), especially the contributions of the sociologist Bruno Latour. As a research strategy, the authors proposed the creation of a cartography of the controversies about a particular urban video surveillance “collective” to be opened soon in the city of Rio de Janeiro - the ISCC (Integrated Security Command Center). Through mapping its associations, the authors look to increase the visibility of these issues of security dispositifs today and of the forms of government as they are performed and experienced at the scene in focus.
