Professional GPS Vehicle Tracking for Investigations
Accurate Intelligence Without Compromise

Our private investigator GPS vehicle tracking service involves the lawful deployment of a covert tracking device to monitor a vehicle’s movements in real time. The technology provides:
• Precise location data
• Speed and direction of travel
• Stop locations and journey durations
• Historical route playback and reporting
GPS vehicle tracking is frequently used as a force multiplier for mobile surveillance, enabling our investigators to maintain contact with a subject vehicle while reducing the risk of detection or loss. This method is particularly effective in investigations where traditional surveillance alone may be impractical or resource-intensive.

When GPS Vehicle Tracking Is Used
Supporting a Wide Range of Investigations
GPS tracking allows us to identify patterns of behaviour, confirm or disprove claims and focus physical surveillance resources where they are most effective. Our vehicle tracking services are commonly utilised for:
Matrimonial and relationship investigations
Asset location and usage verification
Fraud investigations
High-risk or multi-vehicle surveillance operations
The Benefits of GPS Vehicle Tracking
Reliable Data, Reduced Risk
Importantly, GPS vehicle tracking only records vehicle movements. It does not track individuals once they leave the vehicle which ensures proportionality and legal compliance at all times.The primary advantage of GPS vehicle tracking during an investigation is the accuracy and continuity of intelligence it provides.
Benefits include:
• Continuous monitoring without physical presence
• Reduced risk of losing the subject vehicle
• Enhanced investigator safety
• Cost-effective support for long-term surveillance
• Clear, documented evidence of vehicle movements

In many cases, deployment can be arranged quickly following an initial consultation and legal assessment. Urgent cases are prioritised where appropriate.
