How Does a Vehicle Tracker Work?

Vehicle security has become an important consideration for many UK car owners. Modern thieves use increasingly sophisticated methods to target vehicles, so having an additional layer of security can provide valuable protection.

One popular option is a vehicle tracker. But how does a vehicle tracker work, and what actually happens if your car is stolen?

A vehicle tracker uses location technology to determine where your car is and, depending on the system, send that information to an app, online platform or monitoring centre. Modern GPS vehicle trackers can also provide movement alerts, journey information and other useful security features.

Here is how the technology works and what you should know before having a tracker installed.

What Is a Vehicle Tracker?

A vehicle tracker is a small electronic device installed inside a car or other vehicle. Its main purpose is to identify and report the location of the vehicle.

What Is a GPS Vehicle Tracker?

A GPS vehicle tracker uses satellite based positioning technology to determine the location of your car.

The tracker receives signals that allow it to calculate its position. This information can then be transmitted so that you or an authorised monitoring service can see where the vehicle is.

What Information Can a Vehicle Tracker Provide?

Depending on the tracker you choose, you may be able to see your vehicle’s current location, previous journeys, movement and security alerts.

Some advanced vehicle tracking systems can also provide information about battery status, unauthorised movement and whether the recognised driver is present.

How Does a Vehicle Tracker Work?

Although vehicle tracking technology may sound complicated, the basic process is relatively simple.

How GPS Satellites Locate Your Vehicle

GPS satellites continuously transmit positioning signals. A compatible tracker receives signals from multiple satellites and uses them to calculate the vehicle’s approximate location.

Other satellite navigation systems may also be supported depending on the tracking device.

How the Tracker Sends Location Data

Once the tracker determines its position, it needs to communicate that information.

Many real time vehicle trackers use a mobile network connection to transmit location data to a secure tracking platform or monitoring centre.

How You View Your Vehicle’s Location

Many tracking systems provide access through a smartphone app or online portal.

This means you may be able to check the location of your vehicle from your phone, tablet or computer, depending on the system installed.

Does a Vehicle Tracker Work When the Car Is Turned Off?

Many professionally installed vehicle trackers can continue operating when the engine is switched off.

The exact operation depends on the tracker, its power connection and whether it has a backup battery.

What Are the Different Types of Vehicle Trackers?

Not every vehicle tracking system works in exactly the same way.

Monitored Vehicle Trackers

A monitored tracker connects to a professional monitoring service.

If suspicious activity is detected, the monitoring centre may follow an established security process and assist with vehicle recovery where appropriate.

Passive Vehicle Trackers

Passive trackers record location and journey information for later access rather than continuously transmitting live location information.

They can be useful for journey records but may offer fewer benefits when immediate theft response is the priority.

Real Time GPS Trackers

Real time GPS trackers regularly transmit location information.

This allows authorised users to monitor the vehicle’s location through the tracking service.

Insurance Approved Vehicle Trackers

Some insurers may require an approved vehicle tracking system, particularly for certain high value or high risk vehicles.

Always check the exact requirements with your insurer before arranging installation.

What Features Do Modern Vehicle Trackers Have?

Modern car trackers can offer much more than basic location tracking.

Real Time Location Tracking

Live tracking allows you to see the latest available location of your vehicle through the relevant app or tracking platform.

Geofence Alerts

A geofence creates a virtual boundary around a chosen location.

Depending on the system, you can receive an alert when the vehicle enters or leaves that area.

Tow and Movement Alerts

Movement and tow alerts can warn you if your parked vehicle begins moving unexpectedly.

Battery and Tamper Alerts

Some trackers can detect power interruptions, low battery levels or attempts to interfere with the tracking device.

Journey History

Journey history allows previous routes and vehicle movements to be reviewed.

The amount of history available varies between tracking systems and subscription plans.

Automatic Driver Recognition

Automatic Driver Recognition can help a security system determine whether an authorised driver is present.

If the vehicle moves without the recognised driver identification, the system may trigger an alert.

Remote Immobilisation

Certain professionally monitored systems support remote immobilisation under controlled conditions.

The exact process depends on the security product, monitoring provider and applicable safety procedures.

Where Is a Vehicle Tracker Installed?

Professional vehicle trackers are generally fitted discreetly inside the vehicle.

Why Vehicle Trackers Are Usually Hidden

A visible tracker would be easier for a thief to locate and interfere with.

Keeping the device concealed makes it harder to identify quickly if someone gains unauthorised access to the car.

Can Thieves Find and Disable a Vehicle Tracker?

A determined thief may attempt to locate or interfere with tracking equipment.

Professional installation and features such as tamper alerts and battery backup can make this more difficult and provide additional protection.

Does a Vehicle Tracker Need Its Own Battery?

Many trackers receive power from the vehicle but may also contain an internal backup battery.

This can help the tracker continue operating for a period if the main vehicle power supply is interrupted. The exact backup time depends on the device.

How Can a Vehicle Tracker Help if Your Car Is Stolen?

The main security benefit of a vehicle tracker becomes particularly important after a theft has occurred.

Tracking the Vehicle’s Location

A suitable GPS tracker may continue providing location information after the vehicle has been taken.

This can help establish where the vehicle has travelled or where it is currently located.

Working With a Monitoring Centre

With a monitored vehicle tracking system, the monitoring centre can follow the appropriate recovery procedure when a theft is confirmed.

This can provide professional support at a stressful time.

Providing Location Information to the Police

Depending on the tracking service and circumstances, relevant location information may be shared with the police to support recovery.

Car owners should avoid attempting to recover a stolen vehicle themselves.

Are Vehicle Trackers Required by Insurance Companies?

A tracker is not required for every vehicle, but some insurers may make an approved security system a condition of cover.

What Is a Thatcham Approved Vehicle Tracker?

Thatcham Research assesses vehicle security products against recognised standards.

If your insurer asks for a particular category of tracking system, make sure the product and installation meet the requirements stated in your policy.

S5 vs S7 Vehicle Trackers

S5 and S7 refer to different recognised categories of vehicle tracking systems.

S5 systems generally provide additional driver identification functionality, while S7 systems focus primarily on vehicle tracking and monitoring.

Which option is appropriate depends on your vehicle, security requirements and insurer.

Check Your Insurer’s Requirements Before Installation

Do not assume that every GPS tracker will satisfy an insurance requirement.

Check your policy or speak directly with your insurer before choosing a system.

What Are the Benefits of Installing a Vehicle Tracker?

A professionally installed vehicle tracker can add another useful layer to your overall car security.

Improved Vehicle Security

Tracking can work alongside alarms, immobilisers and other vehicle security measures.

Better Chance of Theft Recovery

Location information may help the relevant monitoring service and police locate a stolen vehicle more effectively.

Real Time Vehicle Monitoring

Access to current location information can give owners greater visibility over their vehicles.

Useful Alerts and Journey Information

Movement, geofence, battery and tamper notifications can alert you to unusual activity, while journey history provides additional information about vehicle use.
