Technical surveillance
counter measures

Technical Surveillance Counter Measures (TSCM or Debugging) is the detection of surveillance devices through a physical and electronic sweep.

The value of TSCM

Debugging sweeps are undertaken to give reassurance that you are not being watched.

• In a domestic situation to check whether a partner is ‘spying’ on the other partner.
• For business to ensure that highly confidential information is not being stolen.

The technology

Technical Surveillance Counter Measures is full of lots of jargon and strange sounding names. Here are a few you may read or hear:

• Active and passive bugs. UHF and VHF devices.
• Non Linear Junction Detectors. Spread spectrum.
• Burst transmission. Frequency hopping transmitters.
• Infra-red illumination.
• Tracking devices. Recorders and real-time.
• Telephone line bugs.
• Battery powered, device powered, hard-wired mains powered.
• Key stroke loggers.
• ... and the list goes on.
