This article discusses the construction of a prototype of a platform that provides the integration of video signals from multiple sources. Video sources can be both existing CCTV systems based on analog cameras, modern systems based on IP cameras and individual cameras of various types. The system consists of portable units that provide signal conversion, its encoding, video streaming and transmission over IP protocols. A distributed and modular prototype of the VSI system was developed. The system consists of modular devices that integrate video streams, user terminals and central system. The VSI prototype provides simultaneous access to a large number of real- time video streams . The system is fully modular, which enables easy expansion of both hardware and software. The article presents the obtained architecture and exemplary operating results.
In situations of failure of communication systems or lack of access to telecommunications infrastructure, it is necessary to use alternative solutions. One way is to use vehicles equipped with a variety of data transmission methods. An example of such a vehicle is the Mobile Distribution Point of ICT Infrastructure (MPDIT) which integrates modern and sophisticated ICT solutions. The vehicle is equipped with many different transmitting and receiving devices, however, the range of which is limited. One of the methods of increasing the range and reliability of communication links is the use of MESH networks. MESH nodes are carried by people, they create a dynamic structure, the functioning of which is possible even if some nodes stop working. The paper also presents a way to solve the problem of simultaneously ensuring high network throughput and large ranges by integrating two types of MESH networks.
Mobile Distribution Point of ICT Infrastructure (MPDIT) is an innovative mobile device that integrates modern ICT solutions with advanced hardware architecture with a modular design. The basic function of MPDIT is to effectively increase public safety and counteract and reduce many types of threats, such as natural disasters. The article discusses considered hardware architecture construction solutions for the MPDIT project. It must ensure high reliability of operation in difficult operating conditions, ICT performance in terms of throughput information through a variety of communication channels that cooperate and low latency. Critical is the ability to modify the hardware layer by implementing a modular construction and based solutions based on modern standards and technologies.
The article presents selected results of research conducted by the consortium under the implemented project for national defense and security on “Video Signals Integrator" Acronym – VSI. Project Leader: Warsaw University of Technology. The consortium: Police Academy in Szczytno, Atende Software Ltd., VORTEX Ltd. No. DOB-Bio7/01/02/2015 funded by the National Centre for Research and Development. The essence of the Video Signals Integrator is to acquire and process signals from multiple sources: existing monitoring systems based on analog cameras, modern systems based on IP cameras, different types of individual cameras. The efficient functioning of the device depends on the properly prepared Configuration Database of the Central Video Integrator System. The configuration database contains information necessary to operate the system by users, both in the scope of authorizations (data of users who can use consoles of particular types) as well as sources of streams processed by the system. It also creates the possibility of grouping streams according to their source. This option allows the user to identify the sources of a given signal and the corresponding response. The functional requirements were taken into account in the development of the concept of Configuration Database. As a result of the research, a design of the pilot version of the VSI system will be created, along with complete server software and a full-sized user console.
