Electronic Countermeasures and De-Bugging

At Global Investigations & Security Consulting we have trained, experienced Countermeasures technicians utilizing the most sophisticated equipment in the industry. If you are concerned that someone may be monitoring your activities using eavesdropping equipment or hidden cameras you may want to consider doing an inspection of the premises, commonly known as a ‘Countermeasures Sweep’. We offer free consultations to help you determine if you even need to do a sweep and if so, explain the procedures and answer any questions you may have. For anyone to do a thorough and professional sweep the following equipment must be used by the technician: 


Spectrum Analyzer

Non-Linear Junction Detector

Time Domain Reflectometer

Thermal Imager 

These are very expensive pieces of equipment that most agencies don’t have. 


If you hire someone to do a Sweep, it must be done right or you’re just throwing your money away.

Our founder

Bob Arthur's law-enforcement background includes investigative and management assignments involving violent crime, undercover operations, organized crime, drug enforcement, hostage negotiation, and family crisis intervention.

As a Detective Lieutenant, Bob commanded a Special Enforcement Unit. He also served as an Assistant District Commander and managed a civilian crisis-intervention unit. He later became Chief of Police in Pinetop-Lakeside, where he organized and developed the department. As a private consultant, he was retained to reorganize another police department.

His education and training include a degree in criminal justice, hostage-negotiation training through Northwestern University, FBI management training, U.S. Secret Service dignitary-protection training, and DEA advanced training. He was also a founding board member of the White Mountain Safe House Project.
