Frequently Asked Questions

G-Matrix Systems is a South African IoT engineering company that designs, manufactures, and deploys connected devices and platforms — sold under the RAMAC brand — for security, logistics, infrastructure, and energy applications.

G-Matrix is based at Building 2, Centurion Gate Business Park, Akkerboom St, Zwartkop, Centurion, 0157, South Africa, and deploys solutions across South Africa and the wider African market.

RAMAC is G-Matrix's IoT product ecosystem — a range of low-power sensors and trackers backed by the RAMAC App for configuration, monitoring, and real-time alerts.

G-Matrix serves security and surveillance, infrastructure monitoring, logistics and cold chain, and energy and utilities — anywhere reliable remote monitoring, tracking, or control is needed.

Yes. G-Matrix Systems (Pty) Ltd is a South African company based in Centurion, Gauteng. Its products are engineered specifically for South African conditions and certified for local use.

Yes. G-Matrix is a full electronic design house that develops its own hardware, firmware, and software in-house, and manufactures and tests at production scale rather than reselling third-party devices.

G-Matrix builds the full stack itself — hardware, firmware, software, and deployment. That means it can customise devices, control quality, and support solutions end to end, rather than only reselling someone else's products.

Yes. G-Matrix designs and deploys IoT solutions across South Africa and the broader African market, with hardware suited to remote, off-grid, and harsh-environment deployments.

The RAMAC App is the companion application used to configure RAMAC devices, monitor their status, and receive real-time alerts such as intrusion, tamper, low-battery, and heartbeat notifications.

Most RAMAC sensors communicate over Sigfox (RCZ1), a low-power wide-area network. Several models add Bluetooth Low Energy (BLE) for local configuration, and trackers include GPS/GLONASS for location.

Sigfox is a low-power wide-area network built for IoT. It sends small messages over long distances using very little energy, which is why RAMAC sensors achieve multi-year battery life without Wi-Fi, SIM cards, or local wiring.

No. RAMAC sensors run on the Sigfox low-power network, so they need no SIM card, Wi-Fi, or data cabling. Most are wireless and battery-powered, making installation quick and infrastructure-light.

Yes. RAMAC devices are Sigfox Certified and ICASA Approved for legal operation in South Africa. Selected models also carry IP65 ingress protection for outdoor use.

Battery life depends on the device and reporting frequency. Most RAMAC sensors run 4 to 5 years on a replaceable battery, while trackers and panic buttons are rechargeable and some fixed devices are mains or vehicle-powered.

Yes. RAMAC sensors are engineered for rugged South African conditions and outdoor deployment, with selected models rated IP65 for dust and water ingress. Check the specific product or ask our team for the rating you need.

RAMAC devices are quick to install — most are wireless and battery-powered — and are configured via the RAMAC App. Many mount directly to fences, walls, enclosures, poles, or assets without specialist tools.

Depending on the model, RAMAC devices send real-time alerts for intrusion, tamper, motion, door open/close, low battery, and a daily heartbeat to confirm the device is alive — delivered through the RAMAC App.
