Technical Surveillance Countermeasures TSCM

Research Electronics International


REI, established in the USA, specializes in the design and manufacture of electronic test equipment for security applications. SNSfortech, authorised reseller of REI in Greece, recommends its products to governmental agencies, law enforcement organizations, corporate security personnel, and TSCM professionals, that have a need and responsibility to protect sensitive information. These tools (spectrum analyzer, non-linear junction detector, broadband receivers, thermal imagers, x-ray machines, etc.) are used to detect and locate electronic surveillance devices to prevent or discontinue suspicious activity.


Radio Frequency Detection

REI’s portable spectrum analyzers, near-field detector, and broadband detector RF analysis tools quickly perceive transmitting electronic surveillance devices including hidden cameras, hidden microphones, and other eavesdropping bugs. Each of RF analysis tools detect the emissions given off by a suspicious transmitting device. Equipment in this category range from the easy-to-use ANDRE™ for smaller operations to the advanced OSCOR™ spectrum analyzers for in-depth RF analysis. The hand-held ANDRE near-field detection receiver locates nearby RF, infrared, visible light, carrier current, and other types of transmitters. The OSCOR spectrum analyzers take you to the next level with Spectrogram, Persistence and signal demodulation functionality.


Non-Linear Junction Detectors

The ORION™ Non-Linear Junction Detector (NLJD) detects the presence of electronics, regardless of whether they are radiating, hard wired, or even turned off. Electronics containing semi-conductor properties return a harmonic signature the ORION can detect when radiated with RF energy.  An NLJD detects physical properties, and not energy emissions. Therefore, devices that contain circuit boards and their components, like cell phones, video cameras, and microphones can be detected by the ORION. The ORION antenna head is a transceiver, that radiates a digital spread spectrum signal to determine the presence of electronic components. In this way, it is used to sweep walls, objects, containers, furniture and most types of surfaces to look for hidden electronics, regardless of whether the electronic device is turned on.


Telephone & Line Inspection

The TALAN™ 3.0 Telephone and Line Analyzer is designed to inspect and test analog, digital, and VoIP telephone lines and other wiring for taps and eavesdropping devices. The TALAN includes a built-in automatic switching matrix to perform multiple tests across all pair combinations. Common telephone inspection tests include digital demodulation, frequency domain reflectometry, non-linear junction detection, and digital multimeter. The TALAN 3.0 is able to perform all of these tests along with the ability to act as a high gain audio amplifier and spectrum analyzer.
