Buried cable sensor is a vigilant guard

01 August 2002

Senstar-Stellar Corporation (SSC), a leading supplier of outdoor perimeter intrusion detection security products and systems, is promoting Perimitrax, an outdoor buried cable intrusion detection sensor, on the Gulf market.

"Perimitrax is one of the most innovative, secure and widely-installed perimeter intrusion detection technologies," explains a company spokesman. "The system uses ported (leaky) coaxial sensor cables to create an invisible electromagnetic detection field that detects moving targets based on their electrical conductivity, size and movement. Unless a target possesses the minimum alarm characteristics, it will not be detected. Thus, a person or vehicle crossing through the field is detected while small animals and birds are ignored. Adaptive algorithms filter out common environmental false alarm sources such as foliage, rain, snow or blowing sand and dust."

He continues: "A gap in the transmit cable outer conductor allows electromagnetic energy to escape and be detected by a corresponding parallel receive cable. The resulting detection field is typically 1 m high and up to 3 m wide. When an intruder disturbs the field, an alarm is declared. If networked, the alarm is instantly communicated over the sensor cables to a PC-based central control system.

"The Perimitrax cables can be buried in any medium such as soil, sand, clay, concrete or asphalt to form a uniform, covert, volumetric detection field that is terrain-following.

"Perimitrax's intelligent signal processing provides one of the highest probability of detection (Pd) rates of any sensor type. Combined with the fact that it is not affected by vegetation, rain, snow, hail, sandstorms, wind, fog, temperature changes, RFI, EMI, seismic vibration, acoustic or magnetic effects, this type of sensor has an extremely low false and nuisance alarm rate (FAR/NAR).

"After the cables are installed and the site is returned to its original condition, the volumetric detection field is completely invisible and extends both above and below ground. Since the detection field is invisible, intruders are unaware that the sensor is there. They cannot locate, avoid or tamper with it. These inherent features, in combination with the sensor's advanced technical capabilities, result in the lowest vulnerability of defeat (Vd) of any outdoor sensor."

Senstar-Stellar, a member of the Magal group, develops, manufactures and supplies outdoor perimeter intrusion detection products.

These sensors and systems provide early warning of intrusions into secure areas, reducing the risk of theft, vandalism, harm, sabotage, kidnapping and escape.

For more than 25 years, in more than 75 countries, Senstar-Stellar's products have been used to protect people and valuable assets in high-security applications such as correctional facilities, military and government sites, VIP residences, airports, utilities and nuclear sites.

Senstar-Stellar's product line includes buried cable sensors, fence sensors, electrostatic field sensors, microwave sensors, video intrusion detection sensors, infrared LED illuminators and system integration tools. The company, which is ISO 9002 registered, has operations in Canada, the US, the UK, Germany and Mexico.
