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 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.
The Video Concentration Device (VCD) is the component of the Video Signals Integrator (VSI). The whole VSI is a complex hybrid system containing hardware, firmware, and software components and can integrate and serve video signals from many sources. The VCD is a portable device capturing video signals in various formats from different sources, and transmitting them to the VSI server. Due to high complexity, VCD is equipped with a diagnostic system providing the possibility to remotely manage it. Its functions include the update of the firmware and software, starting the special diagnostic version of the firmware and the software, low-level expert access. In most cases it should eliminate the necessity of the on-site expert’s intervention, except in case of hardware failure
The paper describes the prototype implemetantion of the Video Signals Integrator (VSI). The function of the system is to integrate video signals from many sources. The VSI is a complex hybrid system consisting of hardware, firmware and software components. Its creation requires joint effort of experts from different areas. The VSI capture device is a portable hardware device responsible for capturing of video signals from different different sources and in various formats, and for transmitting them to the server. The NVR server aggregates video and control streams coming from different sources and multiplexes them into logical channels with each channel representing a single source. From there each channel can be distributed further to the end clients (consoles) for live display via a number of RTSP servers. The end client can, at the same time, inject control messages into a given channel to control movement of a CCTV camera.
The purpose of the project is development of a platform which integrates video signals from many sources. The signals can be sourced by existing analogue CCTV surveillance installations, recent internet-protocol (IP) cameras or single cameras of any type. The system will consist of portable devices that provide conversion, encoding, transmission and archiving. The sharing subsystem will use distributed file system and also user console which provides simultaneous access to any of video streams in real time. The system is fully modular so its extension is possible, both from hardware and software side. Due to standard modular technology used, partial technology modernization is also possible during a long exploitation period.
Preventing and eliminating the risks of terrorist attacks or natural disasters as well as an increase in the security of mass events and critical infrastructure requires the application of modern technologies. Therefore there is a proposal to construct a tool that integrates video signals transmitted by devices that are a part of video monitoring systems functioning in Poland.
