Hardware development · Abuja, Nigeria

We develop traffic signal hardware and support it for the life of the junction.

Quadrum Technologies designs signal controllers, their communication cards and the platform that runs them. Partner contractors install; we train their crews, verify every site and stand behind the hardware after handover.

The controller, its communications and the platform are designed together, so one team answers for the whole junction.

TSLC 2.0 junction controller

Our current controller. A backplane carries a comms card, a power card and four signal cards, one per approach, so a fault is cleared on site by swapping a card.

  • Ethernet, Wi-Fi, 433 MHz and 2.4 GHz radio links, RS485, and a GSM option
  • Runs on 9–36 V DC, with a solar-panel charging input
  • Battery-backed real-time clock keeps day plans running if the network drops
  • Inputs for pedestrian push buttons and a police panel: next, hold, manual
  • Hardware watchdog, temperature sensor and fault buzzer

Vision · In development

ANPR and red-light enforcement

Number-plate recognition and red-light violation capture, triggered by the signal state from our own controller.

Talk to us about pilot sites

After enforcement: smart metering.

We develop, train, verify and support. Partners install.

Quadrum Technologies Limited is a Nigerian hardware company, incorporated in Abuja in September 2022. We design and manufacture traffic and other control devices, and back them with engineering consulting. Nigeria comes first; the rest of Africa and beyond come next.

01

Develop

Controllers, cards and firmware designed and tested in-house.

02

Train

Hands-on training for installer crews, operators and maintenance teams, on the hardware and the platform.

03

Verify

Site visits to check each installation against the design before handover.

04

Support

A 24-month warranty, remote diagnostics through the platform, spares and repairs after handover.

Not offered: installation contracts. Partner contractors handle installation and civil works, and we can introduce you to them.

Projects

Wired intersections we equipped with an earlier generation of Quadrum controllers. Both sites have since been upgraded.
