Technical Surveillance Countermeasures [TSCM] are commonly referred to as “debugging”.  Electronic surveillance is a generic term used to refer to the range of activities under “wire-tapping” and “bugging”.  These countermeasures seek to detect the presence of active or passive eavesdropping and other electronic surveillance systems that may be present within a target environment.

These threats include but are not limited to:

• Wireless listening devices,
• Wireless camera’s,
• Hard-wired microphones,
• Analogue or digital recorders,
• Infra-red devices,
• Microwave transmitters,
• 240 volt mains carrier devices,
• Telephone line “taps” or modifications to telephones, and
• A range of other techniques, devices and methods available today.

The FBIS TSCM sweeps include but are not limited to:

• A comprehensive physical search,
• Radio frequency (RF) spectrum analysis,
• Telephone line and device analysis,
• Carrier current analysis including 240V power cabling and outlets to detect devices capable of transmitting information,
• Carrier current analysis of other wiring as appropriate to detect devices capable of transmitting information,
• Non-linear junction detection to detect inactive, dormant or remotely activated devices or electronic components.
