Martin Investigative Services

As former supervisory agents of the U.S. Departments of Justice and Treasury, our private investigators have expertise in all areas of technical surveillance investigation and electronic eavesdropping detection.

We have provided debugging services to officials at the highest levels of government and corporate espionage advice to senior executives of large public corporations. We use sophisticated, state-of-the-art equipment to help your business maintain the integrity of its corporate security.

An electronic eavesdropping inspection includes the following:

  • A threat assessment, including possible parties who would wish to spy on your business and how they might gain access, discussed with the client.
  • A telephone system analysis including instruments, incoming trunks, in-house cabling, and peripheral equipment and testing for intercept devices such as a phone tap or wire tap.
  • A radio frequency (RF) spectrum analysis from 10kHz to 12GHz, including recognition capabilities for digital, spread-spectrum, and frequency-hopping transmitters, in addition to standard analog devices.
  • An infrared (IR) search of all appropriate areas.
  • An electronic inspection for covert video transmission, such as a spy camera.
  • A carrier current analysis of AC outlets, telephone cable, and other wiring to detect devices capable of transmitting communications.
  • A physical search of the target site for hidden microphones, transmitters, audio recorders, closed-circuit television (CCTV) systems, and any other interruption devices.
  • Follow up investigation recommendations if a listening device, bug, wireless camera, or other device is found.
  • An immediate oral report and timely detailed written analysis depicting survey techniques, findings, and recommendations.
