Advanced Vehicle Security and Immobilisation
Car theft is a serious problem in the UK, and criminals are becoming more adept at stealing vehicles through key cloning and relay attacks. The SmarTrack S5+ iMOB is a Thatcham S5-approved vehicle tracking device that fights back with advanced security features designed to stop thieves before they can drive away. This system combines GPS tracking with an intelligent immobiliser that requires driver verification every time you start your car.

The SmarTrack S5+ iMOB uses “No Tag, No Start” technology, which means your vehicle won’t start unless an authorised Driver Detection card or the D-iD app is present inside the car. The immobiliser activates automatically when you switch off your ignition, adding a strong layer of protection against modern theft methods. This car tracker works with all vehicle types, including petrol, diesel, hybrid, and electric cars.
Beyond preventing theft, this vehicle security system offers 24/7 monitoring through Global Telemetrics, GPS tracking across Europe, and battery backup that keeps working even if thieves disconnect your car’s power. You’ll learn how the core security features work, what monitoring services are included, and what subscription options are available to protect your vehicle.
SmarTrack S5+ iMOB: Core Security Features and Operation

The SmarTrack S5+ iMOB combines several layers of protection to prevent unauthorised vehicle use. The system uses immobilisation technology that works with driver recognition to ensure only approved users can start your vehicle.
How ‘No Tag, No Start’ Immobilisation Works
The ‘No Tag, No Start’ system prevents your vehicle from starting unless an authorised driver detection card or the D-iD app is present. When you turn off your ignition, the immobiliser activates automatically and locks down your vehicle’s engine control unit (ECU).
You cannot start your vehicle again without bringing an authorised driver detection card within range or opening the D-iD app on your paired smartphone. This happens before you even turn the key or press the start button. The immobilisation system connects directly to your vehicle’s ECU, creating a physical barrier against theft.
The system stays active even if thieves try to disconnect your vehicle’s battery. An internal backup battery keeps the immobiliser running, so your vehicle remains protected at all times.
Driver Detection and Recognition Technology
The SmarTrack S5+ iMOB uses two methods for driver recognition: physical driver detection cards and Bluetooth driver detection through the D-iD mobile app. Your driver detection cards work like proximity tags, communicating with the tracking device when you’re near your vehicle.
The D-iD app provides a digital alternative that automatically recognises drivers using your smartphone. You need to have the app open and Bluetooth enabled when you approach your vehicle. Both methods meet Thatcham S5+ requirements for verifying authorised users.
If the driver recognition system doesn’t detect your card or active app, the Global Telemetrics Secure Control Centre receives an alert. They will contact you to confirm whether your vehicle is being used without permission.
Automatic and Remote Immobilisation
Automatic immobilisation engages every time you switch off your ignition. You don’t need to remember to activate it because the system works independently. This digital immobilisation system ensures continuous protection without requiring any action from you.
The SmarTrack S5+ iMOB’s immobiliser responds only to police requests for remote activation when your vehicle has been reported stolen. Unlike some tracking systems with customer-controlled remote immobilisation, this approach prevents accidental activation whilst someone is driving.
Your vehicle’s alarm can also connect to the tracking device as an optional feature. When your aftermarket alarm sounds, the Secure Control Centre receives a notification and contacts you immediately.
Compliance with Thatcham S5+ Standards
The SmarTrack S5+ iMOB meets Thatcham Category S5 standards, which specifically address relay attacks and key cloning protection. Thatcham S5-approved devices must include automatic driver recognition and immobilisation features as standard requirements.
This Thatcham-approved system protects against modern theft methods where criminals use electronic devices to copy or relay your key signal. The driver recognition requirement means thieves cannot bypass security even if they clone your key fob.
All major UK insurers recognise the Thatcham S5+ certification. Many insurance companies require Thatcham-approved trackers for high-value vehicles and offer premium discounts when you fit a Thatcham S5 device, such as the SmarTrack 5+ iMOB.
Stolen Vehicle Recovery, Monitoring, and Subscriptions

The SmarTrack S5+ iMOB provides comprehensive stolen vehicle recovery through GPS tracking and 24/7 monitoring by Global Telemetrics’ secure control centres. The system includes flexible subscription options, full warranty coverage, and professional installation across multiple vehicle types.
24/7 Monitoring and Secure Control Centres
Global Telemetrics operates a 24/7 Secure Control Centre that continuously monitors your vehicle across the UK and Europe. If your SmarTrack S5+ iMOB detects unauthorised movement or tampering, the Secure Operating Centre will contact you immediately to verify your vehicle’s safety.
The monitoring service responds to multiple alert types. Movement alerts are triggered when your vehicle moves without the ignition being on. Battery level alerts notify you when the vehicle’s battery is low or disconnected. Anti-tamper monitoring activates if someone interferes with the device or removes the main power supply.
When you report a theft with a crime reference number, Global Telemetrics works with local and national police forces to recover your vehicle. The company also operates an international repatriation network with independent investigators who have extensive local knowledge. This network helps recover vehicles stolen abroad, with European coverage and international roaming capabilities.
Tracking Technology and Theft Prevention
The SmarTrack S5+ iMOB uses multiple tracking technologies to locate your vehicle. The system combines GPS-based tracking with GLONASS, GPRS, and GSM connectivity. This means the device doesn’t rely solely on GPS for obtaining location information.
Your secure online account displays both current and historical locations of your vehicle. The Global Telemetrics app, available for Android and Apple devices, shows up-to-date location information. You can access this data anytime through your mobile device or web browser.
The internal battery backup keeps the device operational even when your vehicle’s power supply is removed. Battery monitoring continuously tracks your vehicle’s main battery voltage. This feature ensures the tracking system remains active during theft attempts involving battery disconnection.
Subscription Options and Ownership Duration
You can choose from several subscription options to suit your needs. Available plans include monthly direct debit, annual subscription, 24-month, 36-month, and duration-of-ownership options.
The monthly direct debit provides flexibility if you prefer shorter commitments. Annual subscription and longer-term plans often offer better value for extended protection. The duration of ownership option covers the entire time you own your vehicle.
All subscription plans include full access to the secure online account, Global Telemetrics app, and 24/7 monitoring by the Secure Control Centre. The manufacturer warranty and monitoring service remain active throughout your chosen subscription period.
