Professional Bug Detectors

🎯 Professional Bug Detectors – Advanced Counter-Surveillance Tools

OzSpy is Australia’s trusted source for professional bug detection equipment β€” serving investigators, government, corporate security teams, and serious users since 1998.

Our range includes advanced RF scanners, spectrum analysers, and non-linear junction detectors (NLJDs), designed to detect hidden surveillance threats like:

  • πŸŽ™οΈ Covert listening devices

  • πŸ“‘ GPS trackers

  • πŸ“· Hidden WiFi or 4G cameras

  • πŸ“Ά Transmitters using Bluetooth, GSM, or unknown RF

Whether you’re protecting sensitive data, performing TSCM sweeps, or responding to surveillance concerns β€” we’ve got the gear to do it right.


🧠 What Makes Professional Bug Detectors Different?

Professional bug detectors are built for performance and precision. Compared to entry-level devices, they offer:

  • Wider frequency ranges – Often detecting up to 14GHz

  • Adjustable sensitivity – Filter background noise and fine-tune detection

  • Frequency display – Identify the exact signal being received

  • Cleaner scans – High-end filters remove RF β€œgarbage” from detection

These units require some learning but deliver much more accurate results.


πŸ“Ά Frequency Range & Signal Clarity

Most surveillance equipment operates under 6GHz. A professional-grade detector that reaches this range (or beyond) ensures:

  • Better detection of hidden WiFi & 4G cameras

  • Identification of Bluetooth trackers and GPS beacons

  • RF awareness in environments with strong interference

Advanced models also display detected frequencies, helping differentiate between threats and harmless signals like routers or phones.


🧭 Key Features to Consider

  • βœ… RF Spectrum Scanning – Wide coverage and deep scanning for weak signals

  • βœ… Signal Identification – Know what you’re detecting: Bluetooth, GSM, WiFi, etc.

  • βœ… Sensitivity Controls – Reduce false alerts in high-RF environments

  • βœ… EMI/EMR Detection – Some models detect electromagnetic radiation from inactive bugs

  • βœ… NLJD Detectors – For powered-off bugs and hidden circuits

  • βœ… Spectrum Analysis – For advanced operators needing waveform insights


πŸ§ͺ What About Lens & IR Detection?

Most professional units skip built-in lens detection and IR scanning β€” these are common in consumer bug detectors. If you need to find hidden cameras visually (like in Airbnbs), consider pairing your pro scanner with:

  • A lens finder

  • A handheld IR detector


πŸ› οΈ How Does a Professional Bug Detector Work?

Think of it as a sophisticated radio receiver scanning across millions of frequencies. It alerts you to unusual transmissions, giving you the ability to track and locate the source β€” whether it’s transmitting live or intermittently.

Some models allow real-time frequency display and signal strength analysis, helping skilled operators pinpoint the threat.


⚑ Are Spectrum Analysers or NLJDs Better?

Both are powerful tools:

  • Spectrum Analysers let you visualise RF activity in real time β€” perfect for investigative work.

  • NLJDs detect electronics even when powered off, ideal for highly covert threats.
