We've done some extensive testing and a lot of research and over the course of last year,— Barry Geer, Inventor of the Securi-Cable and Founder of Seed Africa
He says the system protect low-voltage, medium and high voltage cables from being pulled from the ground.
It includes those cables that feed suburbs and commercial areas, as well as aims to prevent intrusion into manholes, where telecoms cables traditionally are installed.
The system aims to protect all these areas from being vandalised, says Geer.
It's a system to try and protect all kinds of cables.— Barry Geer, Inventor of the Securi-Cable and Founder of Seed Africa
Geer explains how it all works. It involves a passive and active system.
The passive system literally gets clamped to your low voltage cables, which traditionally supply your street lights, and these cables are normally pulled from the ground.— Barry Geer, Inventor of the Securi-Cable and Founder of Seed Africa
He explains how thieves use vehicles to pull hundreds of metres of cable from the ground, and the clamps aim to prevent this.
The more advanced system, he explains, protects the medium, high voltage, and telecommunication cables. These devices are buried underground half-way between the surface and the cables.
This is because when thieves steal these kinds of cables they literally re-dig the entire trench, and then remove these very heavy, expensive cables.— Barry Geer, Inventor of the Securi-Cable and Founder of Seed Africa
When the device detects that the surface is being unearthed, it activates and sends out a data message to a call centre with the exact GPS coordinates.
