Technical surveillance countermeasures
Also referred to as "de-bugging" or "sweeping", but more correctly defined as the detection of active and passive eavesdropping and surveillance devices.
TSCM (Technical Surveillance Countermeasures) is best defined as the application of specialized knowledge and equipment to counter the deployment of electronic surveillance, or bugging, devices. A professional TSCM inspection will involve the detailed examination of many aspects of the area under review, including comprehensive electronic, visual, thermal examinations. All means of audio and video egress from the area are physically and electronically examined for anomalies and vulnerabilities are identified. We use only the most up to date equipment including the OSCOR Green designed for commercial applications to detect illicit eavesdropping signals, perform site surveys for communication systems, conduct radio frequency (RF) emissions analysis, and investigate misuse of the RF spectrum.
We also use the TALAN telephone analyzer for telephone system examinations to include the illicit interception of voice over internet protocol (VOIP).
