Supporting Technical Surveillance Countermeasures with advanced wireless detection
Technical surveillance threats can be difficult to identify. Hidden transmitters, mobile devices and other wireless equipment can operate unnoticed within offices, vehicles, meeting rooms and other sensitive environments.
Comms-Tek provides professional-grade wireless detection equipment that helps TSCM specialists identify, locate and investigate active wireless signals.
Whether you’re carrying out a routine technical surveillance sweep, investigating a suspected device or monitoring a sensitive environment, our solutions provide the visibility needed to support a thorough and effective search.

The challenge for TSCM
Modern surveillance threats are becoming increasingly sophisticated, while wireless technology continues to become smaller, more accessible and easier to conceal.
A device hidden within a room or vehicle may not be visible during a conventional physical search. If it is transmitting, however, it can leave a wireless signature that specialist detection equipment can identify.
For TSCM professionals, this means having the right tools to:
Identify active wireless signals that may otherwise go unnoticed
Locate potential sources within rooms, buildings and vehicles
Distinguish relevant signals from the surrounding wireless environment
Investigate suspected surveillance devices during a technical sweep
Document findings as part of a wider TSCM investigation
Solutions for examinations and test centres
