Technical Surveillance Counter-Measures Hire Our Professional Bug Sweeping Service

Bug Sweeping Services

There’s a spying epidemic that takes place every day among families, neighbors and friends, landlords, businesses and others. If you think you are being wiretapped or followed by someone, there is only one method that can be assured. You need to hire a professional and experienced TSCM technician to inspect your home or business to determine if there are any hidden bugs in the area.

What’s a TSCM Techinciation?

TSCM (technical surveillance counter-measures) is the original United States Federal government abbreviation denoting the process of bug-sweeping or electronic counter surveillance.

About TSCM (technical surveillance counter-measures)

A TSCM survey is a service provided by qualified personnel that detects the presence of technical surveillance devices and hazards and to identify the technical security weaknesses of a facility, thus providing a technical penetration. A technical security survey will provide a professional assessment of the facility’s technical security posture and will normally include a thorough visual, electronic, and physical examination in and about the surveyed facility.

However, this definition lacks the depth of meaning understood among professionals. Comsec, ITSEC, and physical security is just as important as other security needs in the modern environment. The ubiquity of multimedia devices and remote controls have allowed workers to remove massive amounts of data from secure environments without the knowledge of those in charge.

Technical Surveillance Countermeasures (TSCM) are usually a systematic physical and electronic examination of a designated area, in an attempt to discover electronic eavesdropping devices, security hazards or security weaknesses.

Radio Frequencies

Most bugs transmit information, whether data, video, or voice, through the air by using radio waves. The standard counter-measure for bugs of this nature is to search for such an attack with a radio frequency (RF) receiver. Lab and even field-quality receivers are very expensive and a good, working knowledge of RF theory is needed to operate the equipment effectively. Counter-measures like burst transmission and spread spectrum make detection more difficult.

The timing of detection surveys and location scans is critical to success, and varies with the type of location being scanned. For permanent facilities, scans and surveys must take place during working hours to detect remotely switchable devices that are turned off during non-working hours to defeat detection.

Most bugs communicate information to others over the airwaves, whether by data, video, or voice. An effective way to combat bugs of this nature is to detect them with a radio frequency detector. Receivers found in laboratories and in the field are very expensive and require a good understanding of RF in order to operate them effectively. Unpredictable transmission patterns and specific coding make interception more difficult.

The timing of surveys and location scans, and the need to take into account different types of locations. For permanently-installed facilities, scans and surveys must be performed at least during normal working hours to detect remotely-switchable devices that are turned off during non-working hours to defeat detection.

Devices That Do Not Emit Electromagnetic Waves

Rather than listening to conversations, bugs may record them. Some bugs that do not emit radio waves are difficult to detect, though detection can be achieved through various means.

Very sensitive equipment could be used to look for magnetic fields, or for the characteristic electrical noise emitted by the computerized technology in digital tape recorders; however, if the place being monitored has many computers, photocopiers, or other pieces of electrical equipment installed, it may become very difficult. Infrared film can be very difficult to detect in electronic equipment. A large amount of these items will be found through controlled searches.

Other methods focus on detecting residual heat of a bug or power supply which may be located in a wall or ceiling. The point of detection is located by finding a hot spot the camera generates that can be detected.

There is a way to find hidden recorders, as these devices usually broadcast at well-known frequencies that are never totally shielded. A combination of existing techniques and resonance sweeps can often pick up even a defunct or “dead” bug in this way.

Technology most commonly used for a bug sweep includes but is not limited to:

  • Broadband receivers to detect radiating hostile radio transmissions in the near field.
  • Frequency scanner with a range of antennas checking the electromagnetic spectrum
  • WiFi and broadband detection equipment
  • Lens detectors to detect the lenses of wired or wireless concealed covert cameras.
  • Multimeters for general measurements of power supplies and device components.
  • Nonlinear junction detector (NLJD) to detect hidden eavesdropping devices.
  • Oscilloscope for visualisation of signals
  • Spectrum analyzer and vector signal analyzer for more advanced analysis
  • Thermal imagers
  • Portable x-ray machine for checking the inside of objects and/or walls.
  • Videoscopes to inspect small spaces within walls or vehicle crevices
  • Electromagnetic pulse generators to temporarily disrupt or permanently disable electronic equipment.
