Residential TSCM
Investigation of homes and apartments for suspected listening devices, hidden cameras, local recorders and other concealed electronics.
TSCM is the professional process used to investigate suspected hidden listening devices, covert cameras, trackers and other electronic surveillance. In simple terms: it is a professional bug sweep carried out as a structured technical investigation, not just a quick scan with one detector.
TSCM stands for Technical Surveillance Counter-Measures. You may also see the field described as technical surveillance countermeasures, surveillance countermeasures or technical counter-surveillance measures. The purpose is the same: to investigate whether covert surveillance equipment or suspicious electronic activity may be present.
A professional TSCM service can be used for a home, office, boardroom, confidential meeting space or vehicle. The exact inspection depends on the concern and the environment.
Investigation of homes and apartments for suspected listening devices, hidden cameras, local recorders and other concealed electronics.
Professional bug sweeping for offices, meeting rooms, boardrooms and sensitive business environments where confidentiality matters.
Investigation of cars and other vehicles for suspected GPS trackers, listening devices and suspicious electronic additions.
A TSCM bug sweep starts by understanding the concern and defining what needs to be inspected. The investigation may then combine several methods so that normal electronics can be separated from activity that deserves further investigation.
Modern technical surveillance is not limited to an old-style continuously transmitting radio bug. A professional investigation considers the type of threat, how it might operate and whether it would necessarily be transmitting at the time of the inspection.
Concealed microphones, wireless audio transmitters and suspicious audio-capable electronics.
Covert camera devices and suspicious electronics capable of recording or transmitting video.
Suspected tracking devices, including devices that may communicate only periodically.
Voice or video recorders that store information locally and therefore may not create a continuous radio signal.
Equipment that transmits in bursts, at scheduled times or only when triggered.
Unexpected devices, wiring, power sources or electronic behaviour that needs to be identified and explained.
A basic bug detector can be useful for indicating nearby radio-frequency energy, but modern homes, offices and vehicles contain many legitimate transmitters. A beep does not tell you whether the source is a router, phone, Bluetooth device, vehicle telematics system or covert surveillance equipment.
Professional TSCM is concerned with identifying and interpreting what is present, then combining electronic observations with physical inspection and other appropriate methods.
Yes — professional TSCM can investigate devices that are not actively transmitting. We do not rely on RF transmission alone. A voice recorder may save to memory, a hidden camera may record locally, and a GPS tracker may remain quiet between reports.
Different tools address different conditions. A Non-Linear Junction Detector (NLJD) can help locate semiconductor circuitry in concealed electronics even when the device is switched off or unpowered. Our K9-NFD-100 Near-Field Detector is designed to detect powered electronic devices such as GPS trackers, voice recorders, hidden cameras and listening devices even when they are not actively transmitting.
These methods are combined with physical inspection and other technical checks. No single technique can guarantee detection of every device: shielding, installation depth, access and legitimate nearby electronics can all affect an investigation.
The price of a TSCM sweep depends on the size and complexity of the property or vehicle, the number of areas being inspected, the electronic environment, access requirements and the level of investigation required.
We publish guide starting prices so clients can understand the likely cost before making an enquiry. The final scope and price are confirmed before attendance.
Different TSCM companies can use very different methods while describing the service in similar terms. Ask who will conduct the inspection, what technical background they have, whether physical inspection is included, how non-transmitting devices are considered and how suspicious findings are verified.
A professional bug sweep should produce understandable findings rather than simply a list of detector alarms.

Technical Surveillance Counter-Measures: the professional investigation of environments for covert surveillance threats and suspicious electronic activity.
“Bug sweep” is the everyday term. TSCM describes the broader professional methodology used to investigate the environment rather than relying on one detector.
Yes. Vehicle TSCM can investigate suspected GPS trackers, listening devices and suspicious electronics, while recognising the legitimate telematics found in modern vehicles.
Yes. Professional TSCM does not rely only on RF transmissions. We can use an NLJD to help locate concealed electronic circuitry even when switched off or unpowered, while our K9-NFD-100 Near-Field Detector can identify powered GPS trackers, voice recorders, hidden cameras and listening devices that are not actively transmitting.
Cost depends on scope and complexity. We publish starting prices and confirm the agreed price before attendance.
We cover London, Northampton, Milton Keynes and Birmingham, and welcome enquiries for work elsewhere in the UK.
You do not need to know what type of device may be involved before contacting us. Tell us what has caused concern and we can explain the appropriate scope for a professional TSCM inspection.
