At we get at many inquiring calls inquiring about a TSCM (Technical Surveillance Counter Measures) sweep for listening devices. TSCM sweeps have many informal names such as a bug sweep, electronic bug detection or counter surveillance services but whatever you chose to call the service it has one object in mind and that is to find any device with the capability to record audio and/or video of a target without their knowledge. On these sweeps, we use some of the most sophisticated hardware available. We have a hidden camera detector, listening device detection methods, RF video surveillance detection, as well as many other electronic bug sweep devices.
During a TSCM sweep we analyze local RF and attempt to isolate RF frequencies emitting from within the search area. Comparing external RF signals to RF signals analyzed within the search area can help us isolate each signal and determine the location of its source using a triangulation method. We also use a Non-Linear Junction Detection device, a communications wire and network analyzing device and many others. The NLJD allows us to search for electronic bugs even if they are not active or turned off. A thorough physical search is also paramount and a very important part of the process. It takes a team of very skilled personnel to adequately operate the advanced hardware necessary to successfully complete a counter surveillance sweep. So if you’re ever in need of a TSCM sweep don’t hesitate to contact Inc to discuss how are counter surveillance techniques can assist your investigation.
