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.
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.
