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.
