How much time does your team spend calling drivers for updates?

When you're managing several vehicles, even a simple customer enquiry can involve multiple calls.

Fleet tracking gives your team access to real-time and historical location information, helping you understand where vehicles are and review their journeys.

We help businesses explore tracking options that suit their vehicles and operational needs.

Start with one question: what information would make your team's working day easier?

Let's talk about how tracking could help.

What if your vehicle tracker could tell you more than just where your car is?

The Complexus Monitor package combines real-time GPS tracking with advanced vehicle telemetry and diagnostics, giving you greater insight into your vehicle’s location, performance and health.

Simply plug the compact tracker into your vehicle’s OBDII port and start monitoring — no complicated wiring or installation required.

📍 Real-time location, speed & journey history
🔧 DTC fault code diagnostics
📊 Advanced vehicle telemetry
🚨 Geofence, tamper, towing & power alerts
💥 Crash detection alerts
🚗 Driver behaviour monitoring
🔑 Driver identification
📲 24/7 access to the Complexus Location Services Portal

Monitor can detect vehicle fault codes, helping you identify potential issues such as engine or fuel system problems — all while providing the tracking and security features you’d expect from an advanced vehicle tracker.

Whether you want to keep a closer eye on your personal vehicle or gain greater insight into vehicles across your business, Monitor helps you see what’s happening both on the road and under the bonnet.

👁️ Track it. Monitor it. Understand it.

We’re proud to be supporting James as he takes on an incredible 10-day, 10 Peaks challenge in the Lake District, raising funds for Jessica’s Journey – From Tubes to Vocals.

With James heading into areas where mobile coverage can’t always be relied upon, Complexus has provided him with a Garmin inReach Mini 2 satellite tracker, fully set up and ready for the challenge.

🛰️ Satellite tracking
💬 Two-way messaging when off-grid
🆘 SOS capability for emergencies
📍 Location visibility throughout the trek

It means that while James is out tackling the peaks, he has a critical line of communication and a way of keeping those supporting him informed, even beyond normal mobile coverage.

James told us getting everything delivered and set up before departure had “taken a massive weight off my mind”.

We’re delighted to play a small part in keeping him connected and safer throughout the challenge.

Good luck, James, we’ll be following your progress! ⛰️

If you’d like to support the reason behind the challenge, please donate or share James’s fundraiser:

💬 “Absolutely fantastic service. I ordered 2 of the Monitor security packages, one for my car and one for the wife's car so we could track them at all times. The trackers arrived all set up ready to go and it was a case of just plugging them in.

The App is fantastic and gives you real time data of both cars, plus it can detect any faults or issues with the car.

If you are worried about your car being stolen then I would highly recommend these trackers and Complexus.”

Luke ⭐⭐⭐⭐⭐

It’s great to hear how straightforward Luke found the setup and how useful the real-time tracking and vehicle data have been across both cars.

Every business has to start somewhere.

For Complexus, it started in 2001 with a timber office built in the garden, a small, practical workspace where ideas were developed, solutions engineered and work delivered for our earliest clients.

As the business grew, so did our need for space.

Our next chapter took us to Eliot Park Innovation Centre, initially into a small managed office that gave Complexus a professional base from which to continue growing.

Today, we’re still at Eliot Park, just in a much larger office, reflecting how far the business and our capabilities have come.

But our story isn’t really about the size of our offices.

Over 25 years, Complexus has gone from that garden workspace to supporting organisations operating in public safety, critical infrastructure, defence, transport, energy and other demanding environments.

The surroundings may have changed, and the technology certainly has, but the approach that started in that first little office remains:

Understand the need. Engineer the right solution. Test it properly. And be there when it matters.

From a garden office to where we are today, quite a lot can happen in 25 years.
