Specialist Counter Surveillance UK Bug Sweeping Services
Sentry Private Investigators offer specialist technical surveillance counter measures (TSCM), also known as bug sweeping. This is to support individuals, and small to large businesses who suspect they are under threat from technical surveillance attacks which is becoming increasingly common. Where serious concerns of privacy intrusion are present, professional bug sweeps are required to locate, remove and debug properties of hidden surveillance devices. SPI’s expert TSCM technicians are highly skilled and operate with sophisticated detection equipment to ensure that even the most advanced bugging devices are detected and removed to ultimately restore security and peace of mind. Our counter surveillance services are available in Birmingham, London and across the UK.
Residential Sweeps for Bugging Devices

-
Legal matters: Individuals involved in litigation proceedings may require TSCM bug sweeps due to the increased risk of bugging devices being planted in their homes.
-

Cyber security: In addition to physical bug sweeps, maintaining strong online security is crucial to protect sensitive digital information from data harvesting, cyber threats, and unauthorised access.
Discreet & Confidential Bug Sweeping Services
Discretion and confidentiality are the cornerstones of SPI's private investigations and bug sweeping services. We understand the need for privacy and what people are going through when they are feeling unsafe from ex partners for example. We arrange bug sweeps at times to suit the client, often on short notice or outside of normal working hours. This ensures that the process is carried out without drawing attention to staff or members of the family who may be involved in the bugging. All findings, including the detection of bugging devices and the methods used to uncover them, are shared exclusively with the client. Our commitment to confidentiality ensures that sensitive information remains secure and is not disclosed to any third parties. By providing a discreet service, SPI's bug sweeps help clients maintain confidentiality and address security concerns without unnecessary disruption.
Vehicle Bug Sweeps

GPS vehicle tracking devices: These can be placed in discreet locations within your vehicle to monitor your movements. A hidden GPS tracker is a common threat, and our sweep services are designed to detect covert devices. Vehicles can be vulnerable to GPS surveillance, making it easy for perpetrators to monitor their victims movements and other information. Our vehicle bug sweeps involve thorough searches and physical inspections with professional detection equipment to locate any hidden surveillance devices.
-
GPS tracking devices can be deployed to the exterior of a vehicle. GPS trackers provide live location information and can be deployed for months on end without needing to be replaced due to their extensive battery life.
-
Listening devices can be hidden inside vehicles to monitor private conversations taking place.
-
Vehicle bug sweeps require a methodical search with professional detection equipment to eliminate potential surveillance threats.

Preventing the use of spy bugs and video recording equipment: Hidden spy bugs and covert video recording equipment can be used to steal information or record confidential meetings without consent.

When we sweep offices, we perform comprehensive physical searches and inspections of all areas including conference rooms, open-plan spaces and sensitive locations to ensure no listening devices, hidden cameras or other types of spying device are left undetected. Electrical sockets, fire alarms and keyboards for example are common hiding places for surveillance devices which are carefully checked during the sweep. Inspecting WiFi networks is also a crucial step to detect any surveillance devices that may be logged in for transmission purposes.

TSCM Bug Detection Procedures
Our technical surveillance counter measures are conducted to locate and identify hidden audio, video recording and tracking devices by means of a process of eliminating all potential threats that may lead to eavesdropping attacks against individuals or corporate entities. We start the TSCM bug sweep process by conducting a spectrum analysis of all transmitting signals. Our spectrum analysers take a close look at all signals in the area to determine whether they are friendly, or a threat. With our near field frequency detectors we then search for any hidden, covert surveillance devices emitting signals across a broad frequency range (3G, 4G, 5G, Bluetooth, WiFi, GPS etc). The highly sophisticated equipment we use has scanning capabilities to detect all listening devices and video recording devices available on the public market, plus devices utilised by government level agencies around the world. We then force dormant devices (devices not transmitting) to transmit with our array of probing antennas. The next step is to scan for camera systems with our enhanced camera lens and infrared light finders to pinpoint exactly where video recorders have been planted. With use of our T2 antennas we also scan for laser and infrared microphones. Next, we scan with thermal imaging cameras to detect devices emitting heat.
Throughout the bug sweep process, we conduct thorough physical searches with the most effective piece of equipment available, the human eye. Computer keyboards and other electronic equipment will be examined to determine if key loggers and similar eavesdropping equipment is installed A physical and electronic inspection is conducted on all electrical wiring, power outlets, light switches and other electronic equipment. As part of our bug detection services we also complete a physical and electronic inspection of all telecommunications equipment, floor distribution points and individual telephone sockets. On completion of our bug sweeps, we provide a full report of our findings if requested.
Hiding Places for Surveillance Bugs
Available on the open market today are endless types of audio listening devices and video recording devices so small, you would struggle to see them with the naked eye. Once a device is purposefully hidden, the chances of seeing it, let-alone finding it are slim to none. Microphones and camera lenses smaller than a button can be hidden pretty much anywhere, hence why they are often referred to as ‘pin hole cameras’, or ‘pin hole microphones’. Hiding places for such devices are limitless which makes easy work for perpetrators committing acts of privacy intrusion. This is why advanced technical surveillance countermeasures and bug sweeper services are essential. We have the capability to quickly detect bugs, restore security and resume privacy in your own home.

How to Prepare for a Bug Sweep
To ensure the effectiveness of a bug sweep, proper preparation is key. Before we begin a professional bug sweep service, it’s important to inform all staff members, or family members about the upcoming sweep if deemed appropriate. This helps maintain transparency and ensures that everyone is aware of the process. Make sure that all areas of the premises including offices, meeting rooms, vehicles and wherever private conversations are held are accessible to the bug sweeping team. Eavesdropping devices can be hidden in the most unexpected places.
Providing the bug sweeping technicians with any information about suspected surveillance devices, such as unusual activity, specific locations, or types of devices you suspect (like hidden cameras, listening devices, or GPS trackers), can greatly assist in the detection process. Be vigilant for signs of bugging, such as strange noises, unexplained changes in phone lines, or unfamiliar devices, and report these observations to the professionals.
A highly trained bug sweeping team will arrive equipped with specialised equipment to sweep offices and all other environments. By preparing in advance and cooperating fully, you help ensure a high quality service that leaves no stone unturned. This proactive approach not only increases the chances of detecting and removing all surveillance devices but also provides you with peace of mind, knowing your environment is secure and your sensitive information is protected.
