We Engineer IoT.
From Sensor to Platform.
Based in Centurion, South Africa, G-Matrix Systems designs, develops, manufactures, and deploys IoT hardware and software for industries worldwide.
Built by Engineers, for Engineers
G-Matrix Systems was founded with a clear mission: build IoT devices that actually work in the field. Not just prototypes that demo well, but production-grade hardware that survives harsh field environments and runs for years on a single battery.
We saw that companies worldwide needed connected devices — for security, for logistics, for infrastructure monitoring — but the available options were either too expensive, too fragile, or too dependent on infrastructure that didn't exist in the regions where they were needed most.
So we built our own. The RAMAC product range now includes a full suite of IoT devices covering everything from perimeter vibration sensing to cold chain temperature monitoring. Every device is designed, tested, and manufactured in-house.
Three Pillars of G-Matrix
Reliability
Every device is tested to production standards. We don't ship until it works — no exceptions.
Innovation
3D printing, custom test jigs, and a full electronic design house. We solve problems others haven't attempted.
Full Stack
Hardware, firmware, cloud platform, mobile app — we own the entire stack. No outsourcing, no finger-pointing.
