Secure Detect - STI-Series Taut Wire

Safeguards Technology’s ST I Series of Taut Wire Intrusion Detection Systems is based on the traditional concept that revolutionized the perimeter security market by combining a true physical barrier with highly reliable intrusion detection in one cost-effective solution.

Over the years, taut wire intrusion detection systems have established a solid reputation for successfully detecting and preventing perimeter intrusion and escape attempts while maintaining the lowest false alarm and nuisance rates available in the marketplace today. Taut Wire Systems are currently in use worldwide - in all terrains and environmental conditions.

Features and Benefits

* Minimal Maintenance
Taut Wire Intrusion Detection Systems feature minimal maintenance requirements over many years of use.

* Low False Alarm Rate
The combination of the self-adjusting taut wire sensors and the unique high tensile double strand reverse twisted barb wires reduce the false/nuisance alarm rate to less than 1 per km (0.62 miles) per three months.

* EMI/RFI and Climate Proof
The taut wire electro-mechanical sensor is not affected by Electro Mechanical Interference (EMI), Radio Frequency Interference (RFI), climatic or atmospheric conditions, including lightning and electrical transients from nearby power lines.

*Taut Wire Control System
The Perimeter Control Center (PCC) is based on a Pentium platform and communicates with reporting units. It utilizes Safeguards Technology’s Securnet© Software (Microsoft Windows© based) that is extremely user friendly and custom designed specifically for each facility.


Safeguards Technology’s STI Series Taut Wire Intrusion Detection Systems operate using electromechanical sensors incorporated into a taut wire fence. The system provides intrusion detection and a true physical barrier. The system can be installed as a “stand-alone” system, wall/roof mounted or as an add-on to an existing fence. A taut wire fence can also be installed on swing and sliding gates in order to provide continuous detection and protection to any perimeter. For added protection, corners can be fully overlapped or just at the outriggers. At correctional facilities, taut wire systems are typically installed as the inner fence providing both immediate detection and delay.
