The Wi-i Deflexi consists of a detection unit, with 1 or 2 sensor beams. The sensor beam(s) is attached to the fence wires that will be monitored. The Deflexi thus monitors the attached wires for spreading, cutting and propping up.

The Deflexi detection unit has several advantages over traditional surveillance measures. As a standalone system, no better single intrusion detection solution is available. Used in conjunction with existing systems (such as energisers and CCTV surveillance systems), Deflexi amplifies these systems by adding minimal nuisance alarm instances and high probability of intrusion detection, without incurring additional costs for infrastructure.

The Deflexi unit is not affected by:

  • Environmental conditions like rain, mist or wind
  • Electrical arcing or grass growing through the fence
  • Nearby movement of animals, people or other traffic
  • Salt spray and pollutants

The Deflexi unit cannot be bypassed by isolating the electric fence wires. Attempts to tamper with the fence structure (or the Deflexi unit) will cause alarms to be reported.


  • Battery powered – a single D cell battery can last for more than 4 years
  • Wireless operation – No additional infrastructure deployment required
  • Installation and configuration is easy and can take less than 10 minutes per unit
  • Easy integration with existing systems

The Deflexi unit will stay operational whether the energizer is pulsing or not.
