Across Europe, a strong shift is happening in who buys spectrum analyzers and why. The buyers now are law firms, hotel security teams, or corporate executives who are looking out for themselves and their teams. Private investigators have realized that the new surveillance threats hide in the 5G RF spectrum. This article breaks down what has changed, who is most at risk, and how to choose the right detection tool for your specific threat.
Why now? What changed about potential threats
Since we are not all TSCM experts, some threats are not on our radar. To choose the right devices, you need to know what to look for before buying detection equipment.
5G blind spots
New covert devices transmit on bands that older detectors can't see. If your kit was purchased before 2022, it may already miss an entire category of threats.
RF clutter
Smart TVs, presentation systems, environmental sensors, and Bluetooth fill modern rooms with signals, creating cover noise that masks covert devices.
Burst transmissions
Modern devices record continuously and transmit in short, irregular bursts. Catching them requires a spectrum analyzer with a fast enough sweep rate.
Cybersecurity is something many companies have invested in for years, but spectrum analysis is becoming part of that conversation as new devices hit the market.
Additionally, spectrum analyzers and counter-surveillance sweeps were previously large, expensive, and operated by people with very specific training and clearances that no ordinary person could get. This type of equipment used to belong to government agencies or intelligence services, but the reality is now very different.
The same class of tools once locked behind classified agency budgets is now being adopted by corporate security teams, licensed private investigators, law firms protecting privileged communications, journalists, and high-net-worth individuals. One of the most common mistakes buyers make is jumping to the most capable tool available or the cheapest one without considering the use case first. That is why we created this list of defined products and operational requirements to make them easier to use and address specific threats.
Who Is Actually Buying Spectrum Analyzers in Europe?
The buyer profile is more diverse than most people assume. Here's what we're seeing across the market:
For individuals, small businesses, and organizations new to counter-surveillance, Digiscan Labs offers some of the most accessible and user-friendly detection equipment on the market.
Comes with three bands that operate from 50 MHz to 12 GHz. That upper GHz range matters because newer covert devices increasingly operate above 5.8 GHz, and most cheap detectors can’t detect it. It stays sensitive to the short-range, low-power signals that covert devices produce, even in environments like city center offices and other environments with a lot of signals. The iProtect 1216 is also available with the ODA-4 omnidirectional antenna for better lower-frequency coverage.
A great alternative if you need GPS tracking is
iProtect 1217, which comes with GPS Tracker operation mode for vehicle sweeps. It is a bit of a stronger device.
Law Firms and Legal Professionals are investing in equipment that ensures privileged conversations are not intercepted. GSM bugs and cellular-connected covert cameras are invisible to detectors that only cover Wi-Fi and Bluetooth. A compact, easy-to-use solution is
CAM-GX5, which covers 2G through 5G with worldwide regional band selection, plus a separate 2.4 GHz and 5 GHz detection, up to 50 metres. It fits in a bag, so if you are on the go, your protection comes with you.
The Entry point into the Professional Detection
Hotels and Hospitality Security
Guest privacy is a genuine liability issue in the hospitality sector. Hidden cameras in rooms, covert audio devices in executive suites are a real threat. Security teams need tools that combine portability with sufficient capability to sweep a room quickly and confidently. These devices need to be built for daily professional use, which brings us to two great JJN Digital products:
WAM-X10 and WAM-X25 for Detection With Memory
WAM-X10 covers 0-14 GHz and logs up to 4,000 events, each timestamped with date, duration, band, and signal strength. Use it to return to the same space across multiple visits, correlate the logs, and identify patterns a single sweep would miss.
The
WAM-X25 adds a Wi-Fi Network Analyser, Bluetooth Device Analyser with detailed device profiles, and a Direction Find Function for pinpointing the exact signal source. Operates handheld or as a desktop monitoring station.
Delta Series for independent security consultants or PI Investigators
There is a growing community of independent security consultants who have built corporate and legal client bases and who are upgrading their equipment to match the expectations of those clients, and the Delta series is made for it.
The Delta X G2/6 covers 9 kHz to 6 GHz, catching signals present for as little as 2–3 seconds.
The Delta X G2/12 goes up to 12 GHz with a faster sweep rate, and both devices catch all RF devices, analog or digital, constant or intermittent, audio or video, encrypted or unencrypted, detecting short-burst signals like Wi-Fi, Bluetooth, and mobile devices instantly. The device connects to tablets and laptops and provides real-time graphical RF visualization.
EDD-24T and EDD-24XT are for devices that aren't transmitting.
Keep in mind that RF detection only finds devices that are powered on. The
EDD-24T editions remove that limitation because they detect the harmonic response of any semiconductor junction, powered or not. Phones, cameras, recorders, trackers, bare SIM cards: if it contains electronics, it will be found. The
EDD-24XT adds an extendable pole (30–140 cm, 90-degree adjustable head) for walls, flooring, and furniture.
Agency-grade TSCM: executive and government protection
Individuals and Executive Protection
A specific category is the people who attend sensitive meetings at the highest levels, board members, fund managers, senior politicians, and family offices, who have increasingly accepted that their conversations are targets.
At this level, you are expected to sweep environments before high-value meetings, check vehicles for GPS trackers, and maintain a record of the types of RF signals that are transmitting. The tool that most consistently meets this requirement at the professional level is the
MEFF M2-PRO. It is a full-spectrum analyzer running to 24 GHz, made in the EU with a 13-inch HD touchscreen, Sentinel Mode for continuous monitoring, AirTag detection, on-device reporting, and remote access capability.
New OSCOR Max from REI covers 10 kHz to 43 GHz at 1,100 GHz per second, with an auto-switching antenna system performing 125 switches per second. That means no manual changes, no coverage gaps. The Multi-Purpose Probe extends detection beyond RF to carrier current, infrared, ultrasonic, and magnetic leakage threats that RF-only instruments miss.
REI designs and manufactures its entire product line in-house and counts government institutions, law enforcement organizations, and specialist TSCM professionals among its global customer base. Explore the full

A note on legality and responsible use
Counter-surveillance equipment is legal to purchase and use across the EU, UK, and most jurisdictions globally, provided it is used for lawful defensive purposes. Detection and monitoring of your own spaces, vehicles, and devices is universally permitted. The use of this equipment to monitor individuals without their knowledge, to intercept communications, or for any purposes inconsistent with local privacy laws is a different matter entirely and falls outside the intended use of these tools.
SpyShopEurope operates in full compliance with relevant EU and international regulations and notes on all product listings that items must not be used for illegal surveillance of unsuspecting subjects. Browse the complete range of counter-surveillance and TSCM equipment at
