Technical Countermeasures Surveys (Debugging)

Bison Security Group conducts technical surveillance countermeasures surveys utilizing state of the art electronic detection equipment to detect active and passive electronic transmitters. Our personnel are factory trained and remain current with the latest trends in listening devices and detection equipment.

Our equipment consists of the following:

• The OSCOR Omni Spectral Correlator that scans for active electronic listening/video devices transmitting from 10KHz to 21GHz.
• The ORION non-linear junction evaluator that checks for passive electronic listening devices.
• In addition to the above equipment, Bison Security Group also scans electrical power (AC) outlets and miscellaneous cabling such as cable and telecommunications lines for electronic listening/video devices.

Typically our TSCM surveys consist of the following inspections:

• Radio frequency analysis for active clandestine transmitters by band sweeping the radio spectrum, from ten (10) KHz to twenty-one (21) GHz. This includes an examination of the AC outlets.
• A check for passive clandestine transmitters using a non-linear junction evaluator.
• A physical inspection for inclusive electronic items in designated offices, cubicle areas, meeting/board rooms, as well as surrounding open areas, which include the ceilings, light fixtures, coaxial and telephone cables. All fixtures on the perimeter walls, including wall coverings, are inspected. An inspection is also conducted of all air conditioning, heating and cooling vents. A physical search of all furniture in the offices and rooms is also completed. All telephone, electrical and cable outlets are discreetly marked, following the inspection.
• Telephone instruments and fax machines serving the designated areas are physically and technically examined for the presence of eavesdropping devices.
• The final report would note security concerns and discrepancies, with recommendations to provide added security to the premises.
