In-place monitoring systems

Technical Surveillance Countermeasures (TSCM) activities traditionally relied on handheld “sweeping” devices to detect covert bugs. However, these sweeps are restricted to small areas and a very small point in time, unless large dedicated teams of TSCM operators are employed. Nowadays, many bugging devices will exploit this time restriction by using sophisticated transmission strategies designed to foil sweep teams.

To maintain the security and integrity of sensitive sites on a 24/7 basis, an In-Place Monitoring System (IPMS) such as CRFS’s RFeye Guard should be deployed. RFeye Guard uses a high-specification receiver technology, which offers the additional benefit of detecting many low-power and advanced signals that would be missed by lower-specification handheld sweepers.

Our RFeye systems have been deployed globally in highly-regarded government facilities to detect signals of interest, including those used by eavesdropping devices. Since these devices are not guaranteed to operate in obvious parts of the RF spectrum, the ability to continuously monitor the spectrum up to 18 GHz is a critical feature built into our systems. Sweep rates of almost 400 GHz/s and a resolution down to 1 Hz enable the highest possible probability of interception to be achieved.

RFeye Guard is designed to be both distributed and scalable, allowing the operator to monitor multiple areas of interest over very large distances. Deployments can range from a single room to a large facility comprising multiple buildings.

How it works:

  1. A network of RFeye Nodes picks up unexpected signals that are being transmitted from inside the building.
  2. Security personnel are immediately alerted via system alarm (as well as SMS and email).
  3. Using POA geolocation, the source of the transmission is identified.
  4. The signal is captured for later playback and analysis.
  5. The system can also trigger actions in other third party external software, IP security systems, CCTV, etc.
