There’s value to having the right equipment and team working your case on eavesdropping detection. During the sweep of a residence, a covert RF transmitter “bug” was discovered before it could be installed by the adversary. The bug was located inside a briefcase on a shelf in the master suite closet. Two factors led to the discovery, not the least of which was using the right tool for the job.
The first factor aiding in the discovery was the master suite closet being an area of interest. Closets are not normally considered during a Technical Surveillance Counter Measures (TSCM) survey. The client in this case, however, was suspicious that a covert camera may have been placed inside.
The second factor to the success of this sweep was the equipment used to search the closet. A Research Electronics International Orion 2.4 non-linear junction detector (NJD) detected the bug’s components that had been put inside a briefcase. The closet was large, with three levels of shelves on all three walls. Without the help of the NJD, it would have taken several hours to complete a physical search, and the bug may have been missed.
For those unfamiliar with what an NJD does, it helps find the electronic components, such as transistors and diodes, common to all eavesdropping devices, by flooding a suspicious area or target object with a spectrally pure microwave RF signal at between 2.40 and 2.47 GHz. Various frequencies are then monitored for a harmonic signal reflected by the component. The NJD will detect devices that are dormant, broken, or the power supply has been interrupted, like when a battery has gone dead.
The NJD is a sophisticated device that not every TSCM provider has in their equipment inventory. Training, equipment, and experience are important things to check before hiring a TSCM provider. When comparing TSCM providers, price should not be the only consideration. The professionals at PGI have the right tools and staff to discover bugs. Let us help you make a clean sweep.
