DTR

Taut wire based technology, considered the most reliable and robust solution for perimeter intrusion detection.

The technology of DTR incorporates an array of detectors each connected to a pair of barbed wires with multiple sensors per zone, making it a very redundant system with practically no single point of failure. DTR is a very cost effective solution for wall-mounted applications where there is a moderate number of barbed wires.

Features

Detection capabilities

  • DTR triggers alarms when 15-30 kg (33-66 lbs.) of force or more is applied on the barbed wire.
  • Less than 1 false alarm per kilometre per 3 months.
  • Accurately locates intrusions even when there are multiple simultaneous intrusions.

Performance Features

  • Lifespan of over 30 years.
  • Unaffected by wind, temperature changes, rain, hail, snow, dust, UV radiation
  • Single section of DTR can be of 6m to 60m.

Easy & Affordable

  • Could be installed as a standalone fence.
  • Very low power consumption
  • Very low maintenance.

How it works

DTR consists of multiple twisted barbed wires, typically separated in 9- 20 cm (3.5- 8 in.) intervals and stretched along a typical segment of 50 meters (164 ft.).

DTR sensors are mounted on sensor posts located halfway between adjacent anchor posts. An array of tensioned barbed wires is run between the anchor posts, supported and spaced by spirals.

Each sensor is clamped to two adjacent wires. A deflection or cutting of a wire causes an alarm.The wires are spaced sufficiently close together tomake it impossible for an intruder to penetrate them without causing an alarm. For alarmreporting purposes, the sensors in each post are divided into a maximum of six (6) separate alarmgroups, which allows isolation of thecompromised section of the fence (bottomsection, middle section and top section).

This capability, when analysed properly, can distinguish climbing scenarios against other types of intrusions. It will also eliminate nuisance alarms caused by small animals and improve fault isolation.
