Why RF Detection Isn't Always Enough

For decades, RF detection has been a cornerstone of Technical Surveillance Counter Measures (TSCM). However, today’s surveillance threats are increasingly designed to evade conventional detection techniques.

Modern electronic devices may:

  • Remain dormant until remotely activated
  • Transmit only briefly or on demand
  • Operate in deep sleep modes
  • Be concealed within metal enclosures or building infrastructure
  • Use low-power electronics that generate minimal RF emissions

While RF detectors, Near Field Detectors and Non-Linear Junction Detectors (NLJDs) remain essential tools, each has operational limitations. Professional TSCM practitioners increasingly require complementary technologies that can identify threats using different detection principles.

Detecting the Electronics, Not the Transmission

Rather than searching for radio transmissions, the Lockhart Magnetometer detects the alternating magnetic fields produced by powered electronic circuits.

These magnetic signatures are generated whenever current flows through electronic components, regardless of whether the device is actively transmitting.

By focusing on the electronic circuitry itself, the Lockhart Magnetometer enables operators to detect:

  • Concealed surveillance devices
  • Dormant electronics
  • Powered equipment awaiting activation
  • Shielded electronic devices
  • Hidden timers and oscillators
  • Electronics concealed behind metal or within structures

This provides valuable additional intelligence during technical inspections and helps reduce the likelihood of sophisticated devices remaining undetected.

Modern TSCM Requires Layers

RF Detector

  • Active transmitters
  • Wireless signals
  • Ceullular/Wi-Fi/Bluetooth activity

Near Field

  • Localised RF emissions
  • Close proximity transmitters

NLJD

  • Electronic components
  • Semiconductor devices
  • Hidden electronics

Lockhart Magnetometer

  • Magnetic signatures from powered circuits
  • Dormant electronics
  • Shielded devices
  • Low/no RF emission threats

Greater Confidence Through Complimentary Detection

Designed to Work Alongside Existing Detection Equipment

The Lockhart Magnetometer is not intended to replace RF detectors or NLJDs.

Instead, it provides another layer of technical capability that complements existing inspection methodologies.

When deployed as part of a comprehensive TSCM search, the Magnetometer helps operators build a more complete picture of the electronic environment and investigate anomalies that may otherwise go unnoticed.

This layered approach improves confidence in inspection results while helping security professionals adapt to increasingly sophisticated surveillance threats.

Recognised by the International TSCM Community

The Lockhart Magnetometer was awarded the Glenn H. Whidden Award at the Electronic & Technical Surveillance Countermeasures (ERII) Conference in recognition of its innovation and contribution to the TSCM industry.

The award reflects the product’s unique capability and reinforces Komcept Solutions’ commitment to developing practical technologies that address emerging technical security challenges.

Why Choose The Lockhart Magnetometer?

As surveillance technology continues to evolve, effective TSCM requires more than a single detection technique.

The Lockhart Magnetometer gives technical security professionals an additional method of identifying concealed electronic devices, complementing RF detection, NLJDs and other inspection tools to deliver greater confidence during high-security searches.

Whether deployed by government agencies, defence organisations or professional TSCM practitioners, it provides an innovative capability for detecting electronic threats that might otherwise remain hidden.
