Airports, nuclear power stations, industrial and research sites, or even your own garden &#; there are many places that need to be protected against unauthorized access, and often protection is required 24 hours a day, seven days a week. Up until now, the sheer length of the perimeter to be protected and the high costs involved made this sort of protection impossible at many sites. Working in collaboration with a number of companies, research scientists at Saarland University have developed a new type of surveillance technology that enables extended perimeters to be monitored and protected at low cost. The new technology is based on magnetometers (magnetic field sensors) that can be incorporated within smart cables of essentially any length. These cables can themselves be installed into fencing or roadways. The research team is presenting its innovative technology at the major international technology fair Hannover Messe from April 8th to April 12th (Stand C 40, Hall 2 &#; Saarland Research and Innovation Stand).

If an intruder wants to gain access to a secure industrial site, he first has to overcome some sort of physical barrier, typically a fence. If he climbs the fence or cuts the links he will, unavoidably, cause a vibrational disturbance, which will disclose his position to the novel detection system that has been developed by Uwe Hartmann, Professor for Experimental Physics at Saarland University, and research assistant Haibin Gao. No matter how small the disturbance, each movement of the fence influences the Earth's magnetic field and these changes are detected by the system's tiny, highly sensitive magnetometers.
The magnetometer probes are arranged within the cable like beads on a necklace and the cable is incorporated either permanently or temporarily into the fence. The cable can also be buried in the ground, in which case it responds to any changes in the magnetic field above it. The tiny probes form part of a bus communication network and immediately report any physical disturbance or change including information on where the vibration occurred and whether or not the change in the magnetic field was caused by a human intruder.
The researchers need to be able to exclude false alarms triggered by wind, animals or some other harmless cause. This they do by using complex algorithms to analyse the signals generated by the individual sensors. These algorithms are currently being developed and refined in order to unambiguously distinguish natural disturbances from the disturbances caused by a human intruder.
"The smart sensor cable does not require any major conversion work to be carried out before it can be used, and makes barbed wire and camera surveillance superfluous," says Professor Hartmann. "The system does not record any personal data. The sensors report only the information that is needed for protecting property or for monitoring, say, rail traffic: Has a disturbance occurred? If it has, where did it occur and was it caused by human interference? No other information about the person is recorded," explains Hartmann.
The prototype of the "Vibromag Cable" that Uwe Hartmann and his team developed in conjunction with St. Ingbert-based company Votronic Technology GmbH is now to be developed to production standard. This is the objective of a new project starting in August in which the Saarbrücken physicists will be teaming up with three partner companies, each of which became aware of the new technology at the Hannover Messe. The three companies are: Sensitec GmbH, based in Mainz and Lahnau (http://www.sensitec.com), Listec GmbH from Isen (http://www.listec-gmbh.com), and GBA-Panek GmbH whose headquarters are in Kahla, south of Jena (http://www.gba-panek.de).
The Saarland Research and Innovation stand at Hannover Messe is organized by Saarland University's Contact Centre for Technology Transfer (KWT).

For critical infrastructure, keeping a perimeter secure is necessary to protect against breaches and threats. End-to-end perimeter protection requires both physical security measures, such as fencing, and perimeter fence detection systems.
Security fencing is one of the most important forms of property protection. It can be used in industrial or commercial environments to provide maximum security for assets, storage areas as well as open spaces on the property. Security fences can come equipped with additional features like razor wire and barbed wire, as well as sensors designed specifically to detect movement. Other types might include a camera system that will capture any intruders who happen upon its sightline by means of motion sensor detection systems which are also typically installed.
A perimeter security system offers a buffer time against intruders with its location away from the main building outline or footprint. It also protects areas outside of the facility, such as landscaping, loading docks, and outdoor equipment. The fence acts as an effective first line of defense by having sensors that mark your outer boundary while giving you peace of mind about any trespassers who try to enter your property illegally.
Security fencing includes:
Security fencing and perimeter security detection systems are used to provide end to end perimeter protection for critical infrastructures that include:
For critical infrastructure protection, security fencing is a top priority. However, when considering the type of fence to install to keep intruders out, there may be additional costs generated by choosing extra security options such as barbed wire or perimeter detection. These additions will increase the price of the fence and provide an added layer against intrusion.
Senstar provides perimeter security systems that help to detect and delay intrusion attempts. Fence-mounted sensors detect and locate intruders at the fence line before they get inside a property. Senstar offers a range of fence sensors, security lighting, and other types of security solutions to meet the requirements for sites of all sizes.
