Frequently Asked Questions (FAQs)

What is a vehicle tracker and what does it do?

A vehicle tracker is an electronic security system that uses GPS satellite positioning and mobile network communication to monitor the location and movement of a vehicle in real time. In addition to theft recovery, modern trackers provide intelligent alerts, movement detection, and secure data transmission for continuous protection.

How accurate is GPS vehicle tracking?

Modern GPS trackers typically provide location accuracy within a few metres, depending on satellite visibility and environmental conditions. Advanced systems also use assisted GPS and multi-network connectivity to maintain reliable tracking in urban or underground environments.

What is the difference between Thatcham S5 and S7 trackers?

Thatcham Category S5 trackers include Automatic Driver Recognition (ADR), requiring a secure tag or smartphone to confirm authorised driving. Category S7 trackers provide professional monitoring and theft alerts but do not require driver recognition. Insurers specify which category is required based on vehicle risk and value.

Are Thatcham-approved trackers required for insurance?

Many insurers require Thatcham-approved tracking systems for high-value, performance, or frequently targeted vehicles. Compliance with S5 or S7 standards can be a condition of cover or influence premiums and policy acceptance.

How is theft detected by a tracker?

Trackers detect theft using a combination of ignition status, movement sensors, GPS location changes, and predefined security logic. When unauthorised activity is identified, alerts are triggered and monitoring teams can initiate recovery procedures.

What is a vehicle immobiliser and why is it important?

A vehicle immobiliser prevents the engine from starting or the vehicle from being driven unless authorised. It is one of the most effective anti-theft measures available, as it stops theft at source rather than relying solely on recovery.

What is CAN-bus immobilisation?

CAN-bus immobilisation integrates directly with the vehicle’s Controller Area Network (CAN), allowing secure digital blocking of critical vehicle systems. This provides factory-level protection without cutting wires or leaving visible components that could be identified or bypassed.

Can immobilisers prevent modern theft methods such as relay attacks?

Yes. Immobilisers are specifically designed to protect against relay theft, key cloning, and electronic attacks by requiring independent authorisation before the vehicle can be driven, even if factory keys are compromised.

Are immobilisers visible or detectable?

High-quality immobilisers are installed discreetly and leave no obvious indicators. This hidden installation significantly reduces the risk of tampering or targeted bypass attempts.

What role does a vehicle alarm play in security?

Vehicle alarms act as an immediate deterrent by drawing attention to unauthorised access, tampering, or impact. Advanced alarm systems also provide intelligent monitoring and mobile notifications, enhancing both deterrence and awareness.

What sensors are used in advanced alarm systems?

Advanced alarms may include door, boot, and bonnet monitoring, shock sensors, tilt sensors, and motion detection. These sensors work together to identify a wide range of suspicious activities.

Can alarms integrate with trackers and immobilisers?

Yes. Integrating alarms with trackers and immobilisers creates a layered security system where deterrence, prevention, and recovery work together for maximum protection.

Are vehicle security systems compatible with modern vehicles?

Modern systems are designed to work safely with advanced vehicle electronics, including start-stop systems, hybrid vehicles, and modern CAN-bus architectures.

Can vehicle security be managed remotely?

Many modern systems support smartphone apps that allow users to receive alerts, monitor vehicle status, and manage security features remotely, depending on the product installed.

Are these systems suitable for high-value, lease, or fleet vehicles?

Yes. Advanced security solutions are commonly used on high-value vehicles, lease vehicles, and fleets, offering scalable protection, multi-driver support, and remote monitoring capabilities.

Will installing security systems affect vehicle warranties?

When installed correctly by a professional, modern vehicle security systems are designed to integrate safely with manufacturer electronics and should not affect vehicle warranties.

How do I choose the correct security solution?

The correct solution depends on vehicle value, usage, location, insurance requirements, and risk profile. For optimal protection, a layered approach using a tracker, immobiliser, and alarm is often recommended.
