Bug Sweep Specialists

Professional Bug Sweeping

Shapestones performs Professional Bug Detection to Business and Private who need to protect Privacy and Information.

We detect and discover all types of spy bugs, electronic surveillance devices, hidden cameras, GPS trackers, up to government threat level.

We deliver bug sweeping of offices, homes, hotels, meeting rooms, vehicles, armoured cars, jets, yachts or any sensible area.

Our Professional Bug Sweeping is a technical and physical investigation conducted by technicians highly trained in the UK, U.S. and Italy, utilising top counter-espionage equipment and most-effective investigative techniques.

Do you believe that someone may bug your vehicle, home, phone, residence or other location or that you are under surveillance?

Our expert technicians can discover and identify sophisticated surveillance devices that can compromise your privacy or information. You will benefit from the most advanced, professional-grade, counter-surveillance equipment, and expertise that restore your peace of mind.

Our Bug Sweeping Equipment Includes


REI Oscor Green 24 Ghz - Spectrum Analyzer

The OSCOR Green Spectrum Analyzer is designed to detect illicit eavesdropping signals, perform site surveys for communication systems, conduct radio frequency (RF) emissions analysis, and investigate misuse of the RF spectrum. The OSCOR Green is a portable spectrum analyzer that sweeps 8/24 GHz in one second to quickly detect transmitting electronic surveillance devices and ensure that spectrum activity is captured.

Detects bug in any status: On / Off / Stand-by

REI Non-Linear Junction Detector (NLJD)

NLJD finds potential eavesdropping devices in walls, fixtures, furniture, floors, ceilings, vehicle, or other surfaces. NLJDs are devices designed to detect and locate hidden cameras, microphones, and other electronic devices, in any operational mode: active, standby, turned off, radiating, or hard wired. NLJD technology has proven to be most effective in the detection of semiconductors containing multiple layers of silicon, a P-Type and an N-Type, and an essential piece of equipment for efficient “Bug Sweep”.

Countermeasures Amplifier

REI Countermeasures Line Sweeper and Amplifier

The REI high gain audio amplifier used to detect and identify surveillance devices attached to building wiring such as telephone wiring, LAN and server systems, AC Power, Alarm wire etc.

Detects bug in any status: On / Off / Stand-by

Thermal Emission Spectrum

A key piece of equipment to detect heat created by the electricity moving through the surveillance parasitic devices.

Wireless Security

Detection of Eavesdropping Threats and Vulnerabilities of Wireless Communications

Sniffers capture, decode, and analyze network traffic vulnerabilities in real-time.

Physical Search & Inspection Equipment

Bug sweeping involves the detailed physical inspections of areas to locate and neutralise covert surveillance devices.

High Level Standards 

Our professional bug sweeping equipment, technology, TSCM and counter surveillance training and the use of government laboratory grade equipment are considered the standard within governments and agencies around the world.

TSCM Survey

Methods of Inspection

TSCM survey (Bug Sweeping) is a specialized examination of an area or vehicle to detect, locate and identify any eavesdropping devices, up to TSCM Threat Level 9.

We specialize in identifying suspicious RF signals from VLF till 24 GHz, analog/digital and data transmitters, including Wi-Fi (2.4 & 5 GHz), GSM-UMTS-LTE.

After meeting you and evaluating the threat we conduct a quick inspection which allows us to establish the adequate Technical Investigation for your case.

After we have conducted the survey we report back to you on our findings, flagging up particular risks and making recommendations on how to ensure your privacy isn’t compromised.

Our team of professional technicians has vast experience in electronics and telecommunications, with years of military and law enforcement experience.
