Broad-spectrum monitoring

by Mark Rowe

CRFS, an RF spectrum monitoring product company, has launched RFeye Guard. It’s to deliver continuous in-building monitoring of surveillance threats. Based on broad-spectrum monitoring more often found on the battlefield, the product is the Cambridge firm says for use in Government, high value corporate, banking, national critical infrastructure, and data centres.

As the company says, bugging and eavesdropping devices are no longer only the domain of intelligence services but are available freely online and with high sophistication at low cost. Technical surveillance countermeasures (TSCM) has become a corporate level problem, the firm adds. RFeye Guard is a fixed TSCM system designed to identify the presence of transmitting devices, which may operate anywhere within a vast range of radio frequencies. The system identifies electronic devices transmitting from within buildings, capturing events which may be in the form of continuous or burst transmissions.

Traditional TSCM relies on the use of sweep teams who enter a building and search areas for the presence of transmitters.

Nick Balon – General Manager CRFS, said: “Sweep teams can be successful if devices happen to be transmitting when the sweep takes place. However, more modern devices do not usually transmit continuously. Instead, they transmit in short infrequent bursts designed to evade detection. Installed in a room, the RFeye Guard system remains permanently vigilant for RF signals which could sit anywhere within a range of few kHz up to many GHz. It alerts users to the devices presence, and even indicates where in a room the signal source originated from. We know that minimizing false alarms is important to users, so our indoor/outdoor signal differentiation feature also means that innocent use of mobile phones on the street outside can be distinguished easily from real eavesdropping threats inside the building.”

The RFeye Guard is available from CRFS and its distribution partners. The product can be scaled from single rooms to entire office blocks, the makers add.
