What is TSCM?
Simply: after the work, you know whether you can speak privately in rooms you control.
If you have not heard of this service before, start here. You need to know whether you can speak privately in the room. TSCM is an English abbreviation (Technical Surveillance Counter-Measures). In Estonia we search for hidden microphones, cameras and other covert listening devices. You get a written answer.
What we look for
- Hidden microphones, cameras or other covert listening devices
- GPS trackers on cars and spyware on phones and computers
- Pathways that let sensitive talk or images leave a room in secret
When to talk to us
- Before material negotiations or deals
- If you suspect a hidden device at home, in an office or at an event
- If counsel or leadership needs a documented answer
Why wording matters
“Surveillance” is easy to misread as offering monitoring. Our direction is the opposite: we check whether someone has hidden a device against you.
On the Estonian word “luure”
In Estonian, “luure” covers several ideas, including military reconnaissance. We do not offer intelligence or surveillance services. Our work is a technical check of private and commercial rooms.
For background on the Estonian word “luure”, see the Estonian Wikipedia article “Luure”. For industrial espionage in general, see “Tööstusspionaaž”. Those pages explain terms; our work is a technical room check, not an intelligence service.
Service boundaries
You get a report about your own spaces. We do not offer surveillance services or listen to or watch other people. We do not work against legitimate state or law-enforcement surveillance.
Terms in plain language
These short explanations clarify words you may see in a technical inspection description.
- TSCM
- Estonian: Technical Surveillance Counter-Measures
A defensive inspection of rooms for hidden microphones, cameras and other devices that may secretly record or transmit conversations or images.
- Radio frequency (RF)
- Estonian: raadiosagedused
Wireless signals that devices use to transmit information. During an inspection, we look for signals that may come from a hidden transmitter.
- Spectrum analysis
- Estonian: spektrianalüüs
An organised view of radio signals across different frequencies. It helps identify an unusual signal and investigate which device produces it.
- Non-linear junction detector (NLJD)
- Estonian: mittelineaarne siirdedetektor
A tool that helps find electronics even when they are switched off or hidden inside a wall, furniture or another object.
- Thermal camera and thermography
- Estonian: termokaamera ja termograafia
Using a heat image to notice an unusually warm or cool area. The difference can give a reason to inspect an object or part of a wall more closely.
- Electromagnetic
- Estonian: elektromagnetiline
Related to electricity and magnetic fields. In a practical inspection, it means examining energy and signals produced or used by devices.
- Open-source intelligence (OSINT)
- Estonian: avalike allikate uurimine
Purposeful searching and comparison of lawfully public information, such as websites, registers and public documents. It does not mean covertly watching people.
- Industrial espionage

Unlawfully obtaining trade secrets or know-how for competitive advantage. A hidden recording or transmitting device can be one of the methods used.
- Smart glasses
- Estonian: nutiprillid
Glasses with a camera and microphone built into the frame, such as Ray-Ban Meta. They can record images and sound. The recording light is small and easy to miss.
- GPS tracker
- Estonian: GPS-jälgija
A small device that shows another person where a car, bag or other item is. Bluetooth trackers such as AirTag are used the same way. It may be hidden under a car, under a seat or inside the lining of a bag.
- Spyware
- Estonian: nuhkvara
An app or program that secretly collects data from a phone or computer, such as messages, calls or location. When a partner or relative uses it to watch someone, it is often called stalkerware.
