The Wi-i Tremoli is an intelligent detection unit that measures fence behavior. Each Tremoli runs its own detection algorithm, profiling intrusions and discounting environmental effects. Tremolis are installed at regular intervals on the fence, each one detecting intrusions in its area.

The Tremoli detects climbing, break through and cutting of various fence structures. 

Depending on the specific application, a Tremoli detection unit is attached to the fence at 9m-20m intervals. 


  • Detects intrusion attempts while in progress
  • Does not compromise the aesthetics of the fence
  • No wires and conduits required
  • Battery powered – a single D cell battery can last for more than 4 years
  • Allows for rapid deployment of detection devices
  • Installation and configuration is easy and can take less than 5 minutes per unit

Used in conjunction with existing systems (such as energisers and CCTV surveillance systems), Tremoli amplifies these systems by adding minimal nuisance alarm instances and high probability of intrusion detection, without incurring additional costs for infrastructure.
