Stationary 24/7 passive object protection system

Dear Customer,
we present you with a proposal for the implementation of a Stationary 24/7 passive object protection system.

We would like to emphasize that the proposed solution operates on the principle of purely passive monitoring. The system does not emit any of its own radio waves or signals, does not actively eavesdrop on anyone and does not interfere with the legal operation of mobile networks or corporate Wi-Fi. It functions as a highly sensitive radio "receiver and guardian" that only silently analyzes the environment. Therefore, its operation is fully legal, safe for health and has no impact on your company's existing IT infrastructure.

Nowadays, ordinary one-time office inspections can no longer guarantee 100% security. Modern listening devices can transmit data in short pulses or activate remotely after the inspection leaves. Our proposed solution creates a permanent protective shield that analyzes the radio space second by second and immediately detects any threat, including hidden GSM bugs, Wi-Fi cameras or brought spy devices.

📡 What is a stationary 24/7 monitoring system?

Stationary (fixed) design for continuous 24/7 protection of the building. Top TSCM equipment manufacturers offer solutions that are permanently installed in the building. Unlike suitcase versions carried by technicians for inspections, stationary systems run non-stop in the background. They are discreetly hidden and guard the space against bugs that someone might bring or turn on during important negotiations.

Advantages

✅ Advantages

24/7 Protection – Guards the space even during your absence or during important negotiations.
Detection of pulse bugs – Captures even listening devices that transmit only once an hour.
Silent alarm – The security manager receives a warning on mobile/PC without the attacker suspecting anything.
One-time investment – Unlike repeated inspections, it saves money.

❌ Disadvantages

High price – Requires not only expensive hardware, but also complex cabling and installation.
Physical limitation – Protects only those rooms where antennas are permanently installed.
Dependence on power supply – Requires backup power sources (UPS).
Cannot detect passive recorders – Those that only record to a card and do not transmit.

What specific threats does the system protect you from?

The system detects any unauthorized device that uses radio frequencies to transmit information (from low radio waves to 5G and microwaves):

GSM / LTE / 5G bugs – Listening devices that function as hidden mobile phones with a microphone (e.g. hidden in an extension cord or furniture). The attacker calls them from the other side of the world and listens.
Wi-Fi and Bluetooth bugs / cameras – Miniature hidden cameras and microphones that send image and sound via local network or Bluetooth.
Pulse (burst) bugs – The most dangerous modern listening devices. They do not record non-stop. They store sound in memory and once an hour send it to the attacker in a flash (within milliseconds).
Radio modules in brought devices – Bugs embedded in gift items (pens, watches, power banks) brought by visitors or business partners.

How does the system work in practice?

Sensor network – Fixed monitoring probes (antennas) are discreetly installed in ceiling soffits or on the walls of protected rooms.
Environment learning (Radio baseline) – During the first days of operation, the system "learns" which signals in the building are legal (e.g. official company Wi-Fi, regular operator signals from the street).
Instant detection and silent alarm – As soon as a new, unknown signal is activated in the room, the system detects it in a fraction of a second and sends a silent alert to the security manager.

🏢 Cutting-edge technologies for stationary monitoring

📡 1. REI In-Place Monitoring (IPM) – OSCOR

The American company REI, which manufactures OSCOR, offers solutions for permanent building monitoring. These systems use remote receivers (scanners) distributed throughout the building, connected to a central server.

MESA 2.0 with permanent integration – Newer versions of MESA analyzers can be configured for fixed installation.
Main advantage – If the system detects a new wireless signal in the protected meeting room, it immediately alerts the security manager.
Price – approx. €17,000

💼 2. Delta X G2/12 and G2/6

Ukrainian Delta X systems are among the most popular solutions for stationary deployment in Central Europe.

How it works – Hidden antennas and a Delta X control unit are permanently installed in the room, which is continuously connected to a computer.
Software intelligence – It can perfectly "learn" the radio environment around your building.
Price – approx. €19,000

🏢 3. Aaronia Spectran Command & Control (Germany)

German manufacturer Aaronia supplies complex stationary systems for corporations, government buildings and the military.

RF and Spectral building monitoring – The system consists of fixed 19-inch rack-mount spectrum analyzers and special stationary IsoLOG 3D antennas.
Main advantage – Can monitor huge frequency ranges in real time and pinpoint the exact location of transmissions within the building.
Price – €9,000 – €15,000

🇬🇧 4. CRFS (RFeye Nexus & RFeye Guard)

CRFS is a world leader in advanced spectrum monitoring and geolocation.

How it works – Robust, highly sensitive RFeye Node units are permanently installed in the building, continuously scanning frequencies up to 40 GHz.
Main weapon (Geolocation) – Can precisely pinpoint the physical location of the bug on the building map.

🇨🇦 5. ThinkRF & Kestrel TSCM (Canada)

A strategic partnership of two giants: ThinkRF (hardware) and Kestrel (software).

How it works – They use stationary modular spectrum analyzers ThinkRF R5x50.
Main weapon (Software) – Kestrel TSCM Professional software continuously compares captured data and detects even masked signals.

🇺🇸 6. REI SWARM MESA (USA)

A software solution that allows up to 6 separate MESA 2.0 spectrum analyzers to be connected into one permanent network in the building.

Main weapon (OSCOR Evolution) – Instead of one huge system, distribute smaller MESA nodes throughout the building.

🇩🇪 7. Rohde & Schwarz (UMS / ARGUS Series)

German industrial giant supplying equipment for government agencies, armed forces and telecommunications authorities.

How it works – Their stationary monitoring stations (e.g. R&S UMS400) are designed to run continuously for years.
Main weapon – Hardware with laboratory precision covering gigantic frequency ranges.

💡 💡 Important practical note

A stationary radio scanner protects you from transmitting bugs (GSM, Wi-Fi, 5G). However, it cannot prevent someone from bringing a passive recorder into the room that only records to a card and does not transmit anything.

Recommendation: Stationary radio systems in top management offices are always combined with permanent acoustic noise generators (which vibrate windows and walls, thereby degrading any sound recording).
