A monitoring system that operates in a wide range of bands and allows, for example, scanning, analysis and identification of the following types of transmissions:
analogue signals with the possibility of demodulation of AM and FM signals (headphones are not included in the device),
Mobile phone connectivity in CDMA 450, GSM, 3G, and 4G
radio transmissions between 25 MHz and 6 GHz,
Dect standard operating phones,
2.4 and 5GHz WiFi networks,
Bluetooth connection.
Key characteristics of the RF monitoring system include the analysis of signals of modern algorithms, which allow identification of the signal type and measurement of signal strength allow to find and deactivate the wiretap. In addition, the detector can perfectly handle:
detection of signal intrusives in the vicinity,
SMS message detection,
measurement of GSM, 3G and 4G base stations.
The model is also equipped with high detection sensitivity, so the device can quickly scan a room from 10 m2 to 50 m2 . If a suspicious signal is detected, it informs the operator of the indicator light and tone, but it is also possible for the alarm notification to be sent to the control device over the Internet (Ethernet WLAN). The RF monitoring system is able to store data in built-in memory, allowing long-term monitoring of radio activity in the observed area. In this way, it allows detection of devices that operate in "save & forward" mode, including gps locator and voice recorders, which also send short pulses in addition to recording data.
The RF monitoring system shall have an easy-to-read OLED display showing the transmitting signals and signal strength. In addition, for a deeper overview, the user can connect the device to the computer using USB. Dedicated software makes it easy to manage sensor functions, real-time settings, alarms and measurement results.
Operating modes of RF monitoring system for analog and digital transmissions automatic mode - to detect specific signals that exceed the thresholds prescribed by the user. The detected signals are analyzed and updated in real time and stored in the device memory for further deeper understanding. This mode can be activated automatically according to the prescribed plan.
manual mode - to monitor the signal band defined by the operator. Changes in signal strength for the selected belt are displayed as a graph that allows the operator to select a single signal that appears to be suspicious in order to determine the alarm threshold. This mode can also display a range of analog signals in a specified frequency range from 60 to 6000 MHz with a spacing of 2 to 20 MHz. It is also possible to activate the am / fm sound demodulation function.
Search mode - is used to search for analog transmitters. The detector detects the selected frequency band and after exceeding the predetermined threshold, the scan is stopped. The screen shows data typical of each signal,
SMS detection mode - to detect SMS messages on 2G and 3G networks. The user is informed of the signal strength at the moment of sending the SMS data, its duration, data and time of 3 previously detected SMS messages and the total number of sms messages detected,
Interference detection mode GSM and GPS / GLONASS - allows you to check the activity of GSP / GPS / GLONASS jamming through simultaneous measurement of broadband activity in the bands 900 and 1800 MHz,
log display mode - allows the user to analyze stored data when measured with the ability to filter the connection type, set thresholds, and sort results at the end of the event.
The RF monitoring system can be controlled using both function keys and lcd screens. A great comfort is the possibility of remote control and receiving alarms on any mobile device running Windows. The device has a built-in rechargeable battery that allows 4 hours of continuous operation, but can also be connected to a permanent power supply and in this way have no time limits.

The system is designed to detect unauthorized transmission of radio communication signals within the control area:
Meeting rooms and offices;
Test rooms and test equipment;
Prisons and correctional facilities;
Areas with limited use of mobile phones, radios, etc.
The main unit of the system is the control module (CM). CM performs reception and analysis of signals in remote, distributed locations.
The CM recognition area depends on many factors and the estimated average value is between 10 and 50 square metres. The occurrence of illegal signals is shown by light and sound signals directly to the CM or transmitted via ETHERNET or WLAN to the checkpoint computer.
A checkpoint computer can be any windows-compatible desktop, laptop, or tablet that has special software installed.
Ensures continuous monitoring of the radio environment and event log.

ST-154 configuration options:
The minimum configuration consists of a single CM with a light and sound alarm (ver A). The preset is done via a USB port.
This option is intended primarily to control the radio environment within one room.
To cover more than one room in a multi-storey building, there is a variant with alarm transmission to the control point computer via wlan (ver. W) or ETHERNET (ver E/ ver E + POE) using a specially created or existing network.
Software features:
Cm configuration can be performed both separately and for the whole system. Also, there are many setup options. There are special patterns of ignoring frequencies for cellular, mobile and wireless data bands.
Each CM is assigned its virtual image, which allows you to track changes in radio radiation in real time.
For convenience, virtual images are placed on the screen, for example, in accordance with the floor plan of the supervised area.
Direction search mode for locating the transport source is available when you configure multiple modules.
Silent recording mode is always enabled and there are many options for sorting events, depending on the criteria you want.
Ethernet and WLAN configuration allows the device to operate on an existing network infrastructure.
