The Technology

Active Counter Measures is equipped with all the sophisticated counter surveillance technology required for a competent ‘Sweep’. There is no ‘one device’ fits all. The tech we use:

  • Spectrum Analysis (Live)
  • Non-Linear Junction Detection
  • Radio-Frequency Detection
  • Thermal Imagery
  • Borescope Inspection


Industry names of these devices include: Signal Hound, Research Electronics International (REI), FLIR, Elvira, Calibre and more. This technology is used to compliment a detailed physical inspection of the target area, assisting in the detection of eavesdropping surveillance devices.


Project Hudson is an intelligence gathering initiative founded by our partners, The Vanquish Group UK, whereby data on new and up-and-coming threats related to electronic eavesdropping is collected and analysed. This is done to increase their professional capabilities on the ground while performing TSCM Inspections. We receive these monthly risk assessment reports directly from the team on Project Hudson, making sure we are always up to date with what’s out there.

The Project Hudson team scan both public and private sources to ascertain; what current electronic eavesdropping methods are most prevalent, if any new devices have surfaced on the public market, advancements in technology, changes in legislation and much more. This intelligence is then categorized and assessed to determine how it is relevant to TSCM operators.


“A listening device was found in a meeting room this week during a routine security check,” NZ Rugby Union CEO Steve Tew said in a statement. “There was an All Blacks team meeting there earlier in the week. If the device was working properly, and we don’t know that for sure, then they would have overhead that,” Tew told reporters outside the hotel on Saturday. “It is completely ludicrous. I just think it’s a ludicrous concept that there are listening devices being placed in team rooms. I don’t know how that could happen,” Pulver said.

200 Cases

Tracking devices and technology hacking were used in more than 200 stalking cases reported to the National Stalking Helpline in 2018.

90 million

In January of 2020, it is predicted that there is almost 90 million of these listening devices in people’s homes in America alone (Rahul Bhargava).
