In the ever-evolving landscape of vehicle security, one term that has gained prominence, especially here in the UK, is the Thatcham Tracker.

As car theft continues to be a prevalent concern, drivers increasingly turn to advanced security measures to protect their vehicles.

In this blog post, we will delve into the world of Thatcham Trackers, exploring what they are, how they work and why they have become a vital component in the car security market.

Car theft remains a significant issue across the United Kingdom and in many places around the world, with criminals employing increasingly sophisticated methods to bypass traditional security measures.

The need for robust, intelligent solutions to counteract these threats has never been more critical. Recognising this, the Thatcham Research Centre, a leading authority on vehicle safety and security, first introduced the Thatcham Tracker system in the 1970s.

Fast forward to today, a Thatcham-approved tracker has become a sophisticated vehicle tracking and recovery system designed to enhance car security. Thatcham Research, an independent organisation established by the UK insurance industry, sets the standards for vehicle security, among other things.

Thatcham Trackers, therefore, adhere to a set of stringent criteria to ensure their effectiveness in deterring theft and aiding in the recovery of stolen vehicles.

Most Thatcham trackers operate on a combination of GPS (Global Positioning System) and GSM (Global System for Mobile Communications) technology, whilst others also incorporate VHF, GLONASS and MESH.

The GPS component allows for accurate location tracking, while the GSM technology enables communication between the tracker and a monitoring centre. This real-time connectivity ensures that the vehicle’s location is constantly updated and can be monitored remotely, either by the user or a dedicated control centre operated by tracking system manufacturers.

In the event of a theft, the Thatcham Tracker becomes an invaluable tool for recovery.

Once the theft is reported to the monitoring centre, they can track the vehicle’s movements and liaise with the Police to facilitate a swift recovery. The speed and accuracy of Thatcham Trackers make them a formidable deterrent against thieves.

Thatcham Research categorises vehicle tracking systems into various classes, each denoting a specific level of security and functionality.

Whilst the designations have changed over the years, and continue to evolve, the current categories are as follows:

  1. Thatcham Category S7: This category covers basic vehicle tracking systems with GPS functionality. While providing location tracking, they may lack additional features found in higher categories.
  2. Thatcham Category S5: These trackers offer enhanced security features, including motion sensing and automatic driver recognition. They are often equipped with smartphone apps for remote monitoring and control.
  3. Thatcham Category S5 Plus: The highest level of tracking system, S5 Plus includes all the features of the S5 but with the added capability of remote engine immobilisation. This feature allows the monitoring centre to prevent the vehicle from even starting, increasing the chances of recovery.
  1. Insurance Approval: Many insurance providers in the UK require vehicles to have Thatcham-approved security systems for coverage. Installing a Thatcham Tracker can lead to lower insurance premiums as it significantly reduces the risk of theft and aids in quick recovery.
  2. Proactive Security Measures: Thatcham Trackers offer more than just location tracking. With features like automatic driver recognition and remote engine immobilisation, they actively deter thieves and protect vehicles even when the owner is not present.
  3. Quick Recovery: In the unfortunate event of a theft, the real-time tracking capabilities of Thatcham Trackers greatly enhance the chances of a swift recovery. This not only minimises the financial loss for the owner but also aids law enforcement in apprehending criminals.

It’s fair to say, no matter what aspect of life you’re looking at, the technology we use every day has come a long way in a relatively short period of time. This is especially true when it comes to car security.

Whilst the old-school security measures of steering wheel locks, gearstick brackets or wheel boots were once de-rigour for every motorist wanting to protect their vehicle, the high-tech world we live in means that they simply aren’t enough on their own anymore against a determined car thief.

The most up-to-date cars possess technology that enhances the driving experience that would seem like witchcraft just a couple of decades ago. With every ground-breaking automotive advancement we make, the cat-and-mouse nature of security means that there’s always a workaround or loophole they can exploit.

Nothing exemplifies this more than the car tracker.


Vehicle trackers, like every other product on the market, come with a variety of features that their manufacturer hopes will make their product stand out in an ever-more crowded marketplace. Dedicated smartphone apps, control centre support and notifications are commonplace but they also share the need for a signal/connection to make these features a reality.

Depending on which tracking system you buy, it will be able to operate using one, or more, frequencies to help triangulate its position, by working out how long the signal takes to be sent,  received and returned by different satellites in orbit above the Earth.


Across the range of vehicle trackers we sell here at Infiniti, if you look at the specifications of many of them, you’ll see that all of them will use GPS (Global Positioning System). GPS is just one frequency on which their signal is broadcast. Think of it as the baseline.

All GPS satellites broadcast on at least two carrier frequencies. These are ‘L1’ which operates at 1575.42 MHz and ‘L2’ at 1227.6 MHz. It’s also worth noting that newer GPS satellites also broadcast on L5 at 1176 MHz. Unfortunately, these frequencies can be blocked with the right equipment.

Ideally, you want a tracker that doesn’t just rely on one signal, but instead can harness the power, and therefore reliability and accuracy, of multiple networks. Even if one if blocked, the others will still work.

These can include GLONASS, Galileo, LBS, GSM and VHF. All of which can, given the right tools, still be blocked, with the exception of the final one; VHF or Very High Frequency. The reason it can’t be blocked is simply that it’s undetectable. It’s for that reason it’s the signal chosen by military operations across the world.


If, as part of your car insurance policy, the company has asked for the vehicle in question to have an ‘insurance approved’ tracking system installed, then it can be confusing as to what this actually means. In reality, it often means that the tracker they require installing needs to detect any tampering.

This is often standard and can easily be measured thanks to its dedicated smartphone app. This will help monitor and alert you to any attempts to tamper with the vehicle. Whilst the reality is that GPS or GSM signals can be blocked, devices like the Protect and Connect S5 from Vodafone Automotive or the S5+ and Locate systems from Tracker can alert you when there is an attempt to block those signals.
