Practical Investigation

Engineering Experience Applied to TSCM

Our approach combines electronic measurement, physical inspection and engineering judgement. Where a suspect or unexplained item is identified, its construction, circuitry, function and electronic behaviour can be examined in our RF and electronics workshop rather than relying solely on an alarm from a handheld detector.

This practical engineering capability supports the wider Bug Detectors UK team and helps provide clients with clear, evidence-led findings.

Technical Background

More than simply operating a bug detector

Our TSCM work is supported by an electronics engineering team led by Company Director and Head of Engineering Glenn Darien, drawing on more than 40 years of practical experience in RF, analogue and digital electronics, electronic design, test, measurement and fault investigation.

01

RF Engineering

Extensive hands-on experience with spectrum analysis, RF measurement, antennas, transmitters, receivers and complex radio environments.

02

Surveillance Technology

Practical knowledge of professional covert audio and surveillance electronics provides insight into how modern devices operate and how they may avoid basic detection methods.

03

Evidence-Led TSCM

We combine technical measurements with methodical physical and electronic inspection rather than relying on a single handheld detector.

A Different Perspective

We understand surveillance technology because we design it

Our background is not limited to commercially available counter-surveillance equipment. Experience in RF engineering and surveillance electronics gives us a practical understanding of transmitters, digital radio techniques, intermittent signals and the limitations of simple RF detection.

Professional Service

Confidential, engineering-led investigations

We provide discreet TSCM services for homes, offices, meeting rooms and vehicles. Each enquiry is assessed individually so that the inspection is appropriate to the environment and the client's concerns.

Confidentiality

Enquiries and findings are treated discreetly. We understand that clients may be dealing with commercially or personally sensitive circumstances.

Professional Reporting

Where required, findings can be documented with technical observations, relevant photographs and practical recommendations.

London & Nationwide

Services are available in London and throughout the UK, with scope and travel confirmed before attendance.
