Rotaguard incorporates Geoquip's renowned Alpha Sensor GDALPHA detection system which alerts security personnel to any attempted intrusion and allows alarms to be verified by the unique 'listen-in' audio verification.

  • Latest generation precision sensor technology
  • Uses spirawire manufacturing techniques for EMI and RFI immunity 
  • Incorporates lubritube technology for ultra sensitive detection 
  • Suitable for external and internal applications 
  • Superior audio clarity that cannot be matched 
  • Weather resistant and robust construction



The Alpha Sensor is the next generation sensor designed solely for perimeter security. Its patented magnetic construction combined with the very latest techniques in sensor design have resulted in it being the benchmark for the industry. Resulting from many years of experience of sensor design, the Alpha Sensor exploits new manufacturing technology that enhances its performance. Spirawire is a process where the cable is twisted at exact intervals to provide a natural rejection capability against radio frequency and electromagnetic interference. Lubritube is a technique where specially lubricated tubes enable the precision sensor wires to move freely during an attack. High levels of detection are achieved from the improved frequency response that the sensor produces without the need to introduce complex electronic processing or increase the amplitude of the signal which is the main causes of false alarms with old generation sensors. Detection is linear along the entire length resulting in no blind spots, providing a detection range of approximately 1.5m either side of the sensor.
