Technical Surveillance Counter Measures

Vehicle Counter Measures
Vehicle trackers differ from audio bugs in that most utilize a GPS location system linked via satellite. They can be installed in road vehicles, maritime vessels, or aircraft.
Some trackers also function as GSM audio bugs, allowing them to be discreetly placed inside a vehicle to monitor location and listen in. Many of these devices have a dormant phase during certain hours or periods of inactivity, while sensitive motion sensors can activate transmitters upon detecting movement.
Due to changes in movement and location, bugs are often preferred. Although these devices typically emit clear transmitter signals, locating them can be challenging.
Vehicles contain numerous electronic components and moving parts, making it difficult to find hidden devices. Additionally, many trackers are designed to avoid detection, which can lead to them being overlooked during low-level or amateur sweeps.
We are proud to have a skilled team of TSCM experts, one of the few in the UK, ready to conduct searches on yachts, private jets, and high-value vehicles.
Vehicle sweeps can often be completed in under two hours.
