Detect & Neutralise Covert Listening Devices

Private conversations reaching the wrong ears can unravel trust, deals, and reputations overnight. A professional bug sweep identifies when electronic eavesdropping is suspected as well as mitigation actions to restore security.

When to consider

When to consider a bug sweep

A bug sweep replaces suspicion with facts. You don’t need to identify the device; you just need to act on the pattern.

Most clients don’t have proof – they have a pattern. A bug sweep service is the logical next step when:

Competitors seem to know details from closed-door meetings almost immediately.

Private conversations appear in third-party contexts without explanation.

You've found a suspicious wire, modification, or unknown device in your space.

Leaks continue despite changing participants, rooms, or communication methods.

How We Detect Listening Devices

Audio surveillance can be active (transmitting) or passive (hardwired, not emitting). Our listening device detection process is a meticulous sweep for listening devices that finds both.  You’ll receive a confidential verbal summary immediately, then a factual written report. No alarm, no guesswork.

Understanding what's at risk

We identify what information seems to be leaking, and from which environments. This sharpens the entire search.

Telephone and line analysis

Analogue, digital, and VoIP lines are tested for taps, loading anomalies, and unauthorised modifications.

Physical inspection

Many microphones, contact mics, and in-line taps are hidden inside furniture, walls, cables, and power outlets. We look where a scanner cannot.

Non-linear junction detection

This locates electronic components hidden inside walls, objects, or furniture – even when the device is switched off, hardwired, or disguised.

Radio frequency (RF) sweep

Using professional-grade spectrum analysis, we locate active transmitters across a wide frequency range, including burst and non-standard signals that consumer devices miss.

Acoustic leakage assessment

We check for laser window reflection vulnerabilities, duct-borne sound leakage, and structural audio paths that passive devices might exploit.

What We Check That Others Overlook

Our bug sweep services and bug sweep equipment are portable and adaptable – we work across vehicles, temporary spaces, diplomatic premises, and any environment where confidentiality matters.

Contact  microphones

often placed against walls, windows, or pipes; no RF emission, so an electronic sweep alone is useless.

Hardwired microphones

Disguised as electrical outlets, phone sockets, or built into furniture. We inspect, not just scan.

Laser reflection threats

conversations captured via window vibration; we assess line-of-sight vulnerability and recommend mitigation.

Ducted and structural audio

sound travelling through vents, ceiling voids, or shared walls. We check whether your room's physical boundaries can be compromised.

Legacy devices

old security or IT equipment re-purposed as a listening post. We examine every active line and connection.

If You're Not Sure it’s a Listening Device

Sometimes the leak isn’t a hidden microphone. Many people begin by searching for “a bug detector South Africa” solution when they need to detect listening devices, only to discover that modern surveillance threats often require multiple detection methods and specialist equipment to identify reliably.
