Bug Sweep / Bug Detection Services (TSCM) Australia
Professional detection of hidden cameras, listening devices, and tracking systems across homes, vehicles, and workplaces.
What Is a Bug Sweep and When Is It Needed?
If you are concerned about unauthorised surveillance, a professional bug sweep can help identify whether your privacy has been compromised.
Our TSCM (Technical Surveillance Counter Measures) services are designed to detect hidden cameras, listening devices, GPS trackers, and other covert monitoring equipment across homes, vehicles, and business environments. Using a combination of specialised detection tools and physical inspection, we assess areas where surveillance devices are commonly placed and where signals may be present.
We also work extensively with covert surveillance equipment, including hidden cameras and listening devices. That hands-on experience provides a practical understanding of how these devices operate, where they are typically concealed, and where they are most likely to fail. This knowledge directly informs how we approach detection.
Each sweep is carried out by a licensed technician and tailored to the specific environment. Whether the concern relates to personal privacy, workplace confidentiality, or general peace of mind, the goal is to provide a clear, honest assessment of the situation.
What We Detect
A professional bug sweep is designed to identify a wide range of surveillance devices, from simple consumer trackers through to more concealed and hard-wired equipment.
Hidden Cameras and Microphones
Devices concealed in everyday objects, fittings, or fixtures, used to capture video or audio without consent.
GPS Tracking Devices
Both battery-powered and hard-wired trackers used to monitor vehicle location and movement. This includes common consumer devices as well as more discreet installations.
Wireless Transmitters
Devices transmitting over WiFi, GSM, or Bluetooth networks. These are often used for live monitoring or remote access.
Hard-Wired or Concealed Devices
Surveillance equipment connected to power sources or built into fixtures and fittings. Detection relies on a combination of physical inspection and specialised electronic tools.
Each type of device requires a different approach to detection, which is why multiple tools and inspection methods are used during a sweep.
How a Professional Bug Sweep Works
A thorough bug sweep involves more than simply scanning for signals. It is a structured process that combines electronic detection with practical inspection based on how surveillance devices are actually deployed.
Initial Assessment
We start by understanding the environment and the concern. Different situations require different approaches, whether it is a vehicle, a home, or a workplace.
RF Spectrum Analysis
Specialised equipment is used to scan for active transmissions across common frequencies, including GSM, WiFi, and Bluetooth. This helps identify devices that are currently sending or receiving data.
Physical Inspection
Areas where devices are commonly concealed are checked, including fittings, accessible fixtures, and items that appear out of place. This is guided by real-world knowledge of how surveillance devices are typically installed.
Advanced Detection (NLJD where applicable)
Non-Linear Junction Detection is used in certain situations to locate electronic components, even if the device is not actively transmitting. This allows detection of powered-off or dormant equipment in many cases.
Findings and Explanation
Any findings are explained clearly, along with what was detected, what it means, and any recommended next steps. If nothing is found, that is also communicated honestly.
Additional Detection Methods (where applicable)
In certain situations, additional tools such as thermal imaging may be used to identify abnormal heat signatures from electronic devices. This can assist in locating powered equipment that may not be actively transmitting at the time of the sweep. Its use depends on the environment and conditions, and it is applied where it adds value to the overall assessment.
This combination of methods, including RF analysis, physical inspection, and where applicable advanced tools, is what separates a professional sweep from basic off-the-shelf detection devices.
What Can & Cannot be Detected
No detection method is perfect, and part of a professional sweep is setting clear and realistic expectations from the outset.
What can typically be detected
- Active transmitting devices using GSM, WiFi, or Bluetooth
- Most GPS tracking devices, including many hard-wired installations
- Hidden cameras and microphones operating within the environment
- Electronic devices identified through physical inspection and specialised tools
What may require specific conditions
- Devices that are powered off or only activate intermittently
- Equipment that is not transmitting at the time of the sweep
- Devices shielded or installed in a way that limits signal detection
A professional sweep uses multiple methods to reduce these limitations as much as possible, but no service can guarantee 100 percent detection in every scenario.
This is why experience, process, and the use of appropriate equipment are critical to achieving the most reliable outcome.
Bug Sweep Packages
We offer a range of bug sweeping services to suit different environments and levels of concern. Each service is tailored on site, with the scope adjusted based on layout, access, and risk level.
Vehicle Bug Sweep
Designed to detect GPS trackers, Bluetooth tags, hidden cameras, and listening devices within vehicles.
Includes RF scanning across GSM, WiFi, Bluetooth, and GPS frequencies, along with a physical inspection of accessible areas including the cabin, boot, and underbody where applicable. A drive-by scan may also be used to identify motion-activated devices.
Suitable for cars, utes, and most standard vehicles.
Small Home or Office Sweep
For apartments, townhouses, or small business spaces, typically up to three rooms.
Includes RF analysis, wireless signal checks, and inspection of common concealment areas such as fittings, fixtures, and accessible points within the space.
Medium Home or Office Sweep
For larger homes or workplaces, typically up to six rooms.
Includes all elements of the small sweep, with extended inspection time and broader signal analysis across the environment.
Pro Series Residential Sweep
A more detailed sweep for higher-risk situations or when additional assurance is required.
Includes multiple RF passes, expanded physical inspection, and advanced detection methods such as NLJD where available.
Pro Series Commercial Sweep
Designed for sensitive business environments, executive areas, or situations involving higher confidentiality.
Includes all Pro Series features, with a broader and more detailed inspection process suited to commercial layouts and operational requirements.
If you are unsure which option is appropriate, we can recommend the most suitable approach based on your situation.
When you should book a bug sweep
Most people who book a bug sweep are not certain what is happening, but have a reason to be concerned. The service is often used to confirm whether a situation is real or to rule it out completely.
Common reasons include:
- You have received unknown tracking alerts, such as AirTag or Bluetooth notifications
- Someone appears to have access to private conversations or movements
- You have found a device, cable, or item that does not belong
- There are concerns around personal safety or relationship situations
- Sensitive business discussions or information need to be protected
- You want peace of mind before making a decision or taking further action
In many cases, the goal is not just to find a device, but to provide clarity. Whether something is detected or not, a professional sweep gives you a clearer understanding of the situation and what to do next.

Frequently Asked Questions
How long does a bug sweep take?
Most sweeps take between 20 minutes and a few hours, depending on the size of the area and the level of detail required.
Can you detect AirTags and Bluetooth trackers?
Yes. We check for common consumer tracking devices such as Apple AirTags, Samsung SmartTags, Tile, and similar Bluetooth-based trackers.
Can hidden cameras work without WiFi?
Yes. Some devices record locally to an SD card and do not require an internet connection. These are detected through physical inspection and specialised tools rather than network scanning alone.
Do I need to leave during the sweep?
No. In most cases, you can remain present. We will explain what we are doing and walk you through any findings.
Will you remove devices if something is found?
We will show and explain any devices located. Removal or further action can be discussed at the time, depending on your preference and the situation.
Is the service confidential?
Yes. All enquiries and sweeps are handled discreetly and confidentially.
Can you guarantee that nothing is present?
No service can guarantee 100 percent detection in every scenario. We use multiple methods and professional equipment to provide the most thorough assessment possible.
