Mobile & Foot Surveillance Services: Discreet, Real-Time Tracking for Private and Corporate Investigations
Active Surveillance – also known as mobile and foot surveillance – is a dynamic and effective investigative method used to track individuals or activities in real time. Unlike static surveillance that focuses on a fixed location, active surveillance involves continuous movement, allowing our agents to discreetly follow subjects across multiple environments.
At Corporate Investigations, we specialise in delivering bespoke active surveillance solutions for private individuals and businesses across the UK and beyond. Our highly trained operatives use the latest surveillance equipment and techniques to gather clear, admissible evidence without compromising discretion or legality.
What Is Active Surveillance?
Active surveillance is the real-time tracking of an individual or location by a trained investigator using foot, vehicle, or public transport methods. The goal is to follow the subject covertly and collect detailed, time-sensitive intelligence about their movements, behaviour, companions, and destinations.
This investigative tool is frequently used in both private and corporate investigations to provide accurate, real-world evidence.
Note: Active surveillance should not be confused with mobile phone tracking, which is illegal for private investigators in the UK.
Our Active Surveillance Methods
At Corporate Investigations, our operatives are experts in the art of covert surveillance. They remain flexible and adapt to changing circumstances to ensure complete coverage of the subject’s activity, using methods such as:
- Foot Surveillance – Ideal for close-range tracking in public areas while blending seamlessly into the environment.
- Motorbike Surveillance – Perfect for navigating traffic and keeping pace in urban locations.
- Public Transport Tracking – Utilising buses, trains, or taxis to follow the subject discreetly through cities and towns.
- Water or Air Surveillance – For complex or long-distance operations, our agents can use boats or aircraft to maintain surveillance.
Every method is conducted legally, ethically, and discreetly to ensure accuracy and confidentiality.
