Satellite Telecommunications To Improve Security

Jul 3, 2007 12:43 PM

Two companies are implementing a European Space Agency-supported project to introduce alarm monitoring and video surveillance via satellite to meet the increasing demand for security systems from the government and corporate market, reports the Science Daily.

The two companies are UK-based satellite operator Orbit Research Ltd. and the German company MediaMobil Communication GmbH. They have announced their intention to introduce the Satellite Alarm and Surveillance System (SASS) to the UK market. SASS is independent of terrestrial infrastructure and can be interfaced with standard video surveillance systems.

SASS enables the interconnection of alarm and video surveillance systems to security centers via satellite. Alarm messages and live video images can be simultaneously transmitted. The video images can be used for alarm verification or for surveillance. Bi-directional audio and Internet-like data channels provide emergency voice communications and remote control of devices such as cameras. The system can provide primary or redundant connectivity for security systems where terrestrial networks are either not available or are unreliable.

Orbit's SASS satellite terminals can be deployed at any location within the coverage of the Eutelsat Eurobird-3 satellite. The terminals consist of a three-foot outdoor antenna and an indoor interface unit. This indoor unit provides standard interfaces for the connection of alarm panels, CCTV cameras, telephones, microphones, speakers and a standard computer data port (Ethernet) for user-defined applications. The installation and activation of the satellite alarm terminals is done by a network of certified security installers.

The terminals are linked via a geostationary satellite to the ViaOrbit hub in the UK. From the hub, all traffic is routed via broadband networks to alarm response centers. The satellite transmission links are controlled by the ViaOrbit network operations center.

SASS meets European and British standards in terms of quality-of-service, alarm transmission time, line fault reporting time, availability and information security. SASS developed this advanced mechanism for the allocation of satellite network resources dependent on traffic priorities, bandwidth on-demand management and real time monitoring of the end-to-end transmission links.

Developed under the ARTES Start-up Projects initiative, SASS underwent successful three-month field trials connecting, among other sites, a nuclear power plant in Slovakia to the International Atomic Energy Agency (IAEA) headquarters in Vienna, Austria. IAEA tested the ability of SASS to monitor nuclear facilities in near real-time. SASS was able to provide higher quality information in a shorter time than conventional systems.
