With cable theft continuing to plague a variety of properties, First Response Group (FRG) has unveiled FRG Tremors, a seismic detection system that senses tampering to both laid cable and cable drums in storage, tracking stolen cable in real time.
The system uses seismic sensors to monitor vibration, tilt and movement around cabling and associated infrastructure. When tampering is detected, an encrypted signal is transmitted to FRG’s control centre, which alerts nominated response teams and police. If material is removed, onboard GPS with jamming detection activates, enabling stolen cable to be tracked in real time until recovery by law enforcement. Each unit operates autonomously on a battery for up to three years and is engineered to function in remote or exposed environments.
“Cable theft has become one of the most damaging and costly crimes facing UK infrastructure,” said James Reed, head of construction and infrastructure at First Response Group: “FRG Tremors changes the model from passive surveillance to active response; we can identify an attempted theft in seconds, deploy canine or mobile units, and prevent the damage before it occurs. For operators already battling inflation and budget pressure, the cost of prevention is now far lower than the cost of recovery.”
