Among the new features of this edition, Siemens presents the Siveillance SitelQ intelligent video analysis system and the linear detection system for fires using a fiber optic sensor cable Fibrolaser III.

Siemens has presented at SICUR 2012 your latest news in systems, security solutions and services for infrastructures and cities adapted to each specific need. This technology ranges from crisis management through integrated control systems and platforms to intelligent video surveillance., which provides a substantial improvement in security while protecting the most critical infrastructures.

One of these innovative security solutions is the Siveillance family, specially designed for the protection and integration of electronic systems in the field of critical infrastructures and public or private buildings. Siveillance SiteIQ WA intelligent video analysis technology offers a solution especially focused on outdoor surveillance of large perimeters and critical infrastructures, enabling the implementation of proactive security policies.

This management system not only notifies intrusion alarms, but also categorizes the event that caused the alarm, indicating the typology and providing additional information to the mere detection of alarms.. The system indicates if the identified object is a person, a vehicle, barco, plane, etc., enabling optimization of CCTV infrastructure and related control center personnel. Thanks to the minimum requirement for the number of active pixels on white, allows detecting very small objects, which makes it possible to increase the separation between camera locations and by extension, reduce the number required to protect a perimeter. On the other hand, and by allowing automatic wind detection over multiple video images, a single operator can control a greater number of monitors, than with other similar systems, what translates is a reduction in the number of operators in the control center and therefore a significant cost savings.

Comprehensive system for simple security management

Another centralization solution for security installations is Siveillance Fusion. It is a centralized solution that combines access control, video surveillance and intrusion protection on a single platform. Using existing IT infrastructure and the .NET platform, Siveillance Fusion enables complete interoperability. The platform offers a complete overview and control of a corporation's day-to-day security operations, ensuring global knowledge of the situation.

Siveillance Fusion as a flexible system, Scalable and intuitive covers a wide spectrum of applications. It is suitable for both individual installations and organizations that have different branches.. All security applications are dynamically presented on a single screen. The system allows for operator station-based clients and Web clients.. For greater safety and energy efficiency, Siveillance Fusion can integrate with building management and fire protection systems.

Siveillance Fusion integrates multiple security disciplines into a single platform, providing agile and efficient handling of alarms and security management, as well as what has become known as centralized global situational awareness. Video management function ensures integration of analog and IP cameras for video streaming or network logs, including network video recording options (NVR) and video management system (VMS). The digital video recorder (DVR) allows recordings in different locations, that can be viewed either locally or from any remote location, regardless of where the records were made.

Video systems easily link to door access control systems, to verify the identification of people, For example. Access control functionality protects doors and barriers, guaranteeing access only to authorized people at the right time. If an incident occurs, the reporting tool would easily extract the relevant information and accompany it with corresponding visual information.

Centralized functions are completed by intrusion protection systems that offer early threat detection. The cameras, Access readers and detectors can be placed individually according to needs, offering centralized global situational awareness. If an event occurs, it is easy to identify the exact location and take the appropriate action.

Effective fire detection

Siemens has also presented the Fibrolaser-III at SICUR, which is a linear temperature detection system that uses fiber optic sensor cables and, due to its measurement characteristics, It is especially suitable for fire control, no operating problems, of hazards or objects where conventional fire detection may fail due to local and environmental conditions, thanks to its immunity to electromagnetic interference and its zero need for maintenance. The basic architecture of the system is based on the installation of sensor cables of up to 10 km length per canal, which are monitored by optical controller units called OTS, available in configurations 1, 2,4, 6 y 10 km with one or two measurement channels.

In the case of the Fibrolaser-III OTS controller, uses semiconductor laser diodes and a new type of signal evaluation procedure based on Optical Reflectometry in the Frequency Domain (OFDR acronym in English), which allows us to measure both dispersion effects (Rayleigh and Raman scattering) in optical fibers up to 10 km of length. Thanks to the optimization of measurement time and spatial resolution offered by the new system, it is possible to visualize temperature changes at a point, as well as temperature increases and the relationship between the temperature of an area with adjacent areas, safely and without malfunctions.

The system based on OFDR technology allows a more homogeneous measurement in terms of spatial resolution, especially in extended lengths. Siemens only offers four types of halogen-free sensor cables with flame retardant jackets. (FRNC), with steel reinforcement (SWLT), high temperature (HT) and for Eex applications. It has VdS approvals with reduced measurement cycles of up to 5-6 seconds and spatial resolution up to 0,25 m; two measurement channel system, with the possibility of implementing linear detection systems of up to 20 km; and controller units and cables for applications in explosion risk areas, ( Gas and Dust). Simulation software is available to verify alarm activation time in tunnels and service galleries.

For these reasons, Fibrolaser-III is especially suitable for detecting fires in places where the use of conventional fire detectors is not possible., due to extreme environmental conditions.

Numerous advantages

Among the advantages of this system are that it is a component of a linear fire detection system that can detect hot gases and radiated heat and is adaptable to individual objects; Sensor fibers do not contain electronics and, therefore, the system is immune to electromagnetic problems of all kinds, making it an ideal system for temperature measurement in electromagnetically contaminated areas; sensor cable design (useful life of 30 years approx.) It is very robust and, therefore, resistant to environmental influences, like the temperature, pressure and humidity changes, but also to pollution and gas leaks, which may contain a considerable amount of corrosive materials; Sensor cable installation is very simple, as well as its maintenance. Defective spots can be easily repaired by performing fiber splices; Control units have included the option of one or two channels. OTS30XX-LR enables extended range applications (until 20 Km) or closed loop redundancy applications, taking advantage of having sensor cables with two optical fibers each ( closed loop redundancy of up to 10 km); and the sensor cable can be cut to the required length according to the length needed for each project.

It allows the reading of several parameters among which are the exact location of the fire or hot spot that, depending on the layout and equipment of the operations center and visualization, It is represented in larger or smaller sections called zones; information on the direction in which the fire or hot spot spreads, allowing output graphics; triggering pre-programmed control processes for traffic signaling, ventilation control, video systems and fire suppression systems, etc. via the OTS controller communications interface; and the possibility of integration into MM8000 management systems, Scada…

The main applications of this system are traffic and railway tunnels., conveyor belt protection, in underground mining, in various production areas to control the facilities, for the protection of explosive areas in refineries; for platforms and cable shafts of electrical substations and radioactively contaminated areas (temporary storage, pump wells).

Besides, Siemens is showing at SICUR its wide range of devices for the rapid and reliable detection of fires, combining mathematical algorithms and its patented advanced signal analysis technology ASA Tecchnology, as well as other solutions and services of interest, as your Remote Operations Center, which represents a new dimension in technical assistance in fire protection and building automation.
