TSCM/Bug Sweeps


TSCM Bug Sweeps


Crossroads Investigations offers “Electronic Eavesdropping Detection Service” to combat the epidemic of illegal eavesdropping. TSCM (Technical Surveillance Counter-Measures) services are offered on a one time, periodic, or contractual inspection basis.

If you feel you have been targeted by information thieves and in need of an electronic bug sweep, please call us from an off-premise telephone.

TSCM is a counterintelligence activity and refers to the countermeasures that are employed to detect, defeat, or nullify attempts to gain information, whether proprietary, privileged, or confidential or of a personal nature through the use of a variety of electronic eavesdropping, recording, and other listening and transmitting devices.

TSCM services require a combination of skills and specialized knowledge about electronics, counterintelligence, countermeasures, physical security, investigations, and many other disciplines, all in an attempt to prevent the gathering of information from a subject without the entities knowledge.

TSCM, sometimes referred to as “debugging” or “sweeping”, detects the presence and location of active/passive eavesdropping and other surveillance devices. It also detects and identifies existing or potential information, security, and other communications vulnerabilities.

Crossroads Investigations will not accept TSCM assignments that may interfere with ongoing law enforcement investigations.

  • Client Information

  • Phase 1 - Radio-Frequency Emissions Detection. This phase detects the most common bugging devices: active radio-transmitters (audio, video, cellular and data), digital bugs and cameras operating via Wi-Fi, rogue Wi-Fi access points on your networks, and Wi-Fi security and compliance issues. A spectrum analysis exam covers an area of approximately 100 foot radius. It may be performed exclusive of Phases 2 and 3 if desired. If available, please submit a floor map. Indicate the Phase 1 and/or Phase 2 areas being inspected. We will compute the number of spectrum analysis exams required.

  • Phase 2 - Physical Examination This phase detects devices, which do not transmit radio waves. This phase includes: non-linear junction detection (NLJD), thermal imaging, carrier current, enhanced optical, wiring and general visual inspections.

  • Phase 3 - Communications Examination. This phase of the inspection includes communications equipment associated with Phase 2 areas: telephones (analog, digital, VoIP), speakerphones, fax machines, print centers, video-teleconferencing equipment and their associated wiring / equipment racks.
