QM-5000 is an advanced network system for complex protection of an object against eavesdropping. The system allows parallel connection of up to 10000 MRA-5Q radio analyzers and DMC-3Q detectors of mobile communication to a single PC. There can be 9x128 devices connected using a dedicated object network and up to 200 such object networks can be connected remotely using internet. QM-5000 allows full remote control of each device, and supports numerous additional features like spectrum analysis in the range of 34-5900MHz, background statistic, new signal statistic, automatic audio sampling, frequency and spectrum records, selective statistic, system statistic, etc. All these features are easily accessible from the QMaster software - a user friendly control application with ergonomical graphical user interface. QM-5000 is not only a comprehensive solution for object permanent protection, but also a very effective tool for electronic countermeasures specialists since it gives a clear graphical picture of the current RF signals. QM-5000 allows to detect and record even such dangerous systems like spread spectrum, or modified WiFi, DECT, and GSM.


The MRA-5Q is an advanced automatic radio scanner suited for instant detection of various types of radio bugs in the frequency range 34-5900 MHz. The basis of the system is the radio spectrum memory combined with an ultrafast scanning. The whole frequency range is scanned every eight seconds and the currently received signals are compared with the initially stored "clean" background spectrum. The presence of a new signal activates a three level alarm output and time \& frequency information are stored in the new signal memory. Although the MRA-5Q alone is a very effective protection tool against RF eavesdropping when connected to the QM-5000 object network controlled by the QMaster software its efficiency and functionality is greatly extended.

DMC-3Q is an advanced highly sensitive selective radio frequency analyzer automatically monitoring frequency range from 860 to 2500 MHz. The DMC-3Q devices can be connected to an object bus and then all events and parameters can be monitored and controlled from a master PC. DMC-3/DMC-3Q is designed for detection of mobile phone activity and for protection of objects in which is usage of mobile wireless terminals prohibited. The detected frequency spectrum is divided into 4 sections according to the ETSI telecommunication standard - GSM, UMTS, DECT+TDD, WiFi+Video+Bluetooth. The main advantage of DMC-3/DMC-3Q is the detection of communication in the 3G (UMTS) telecommunication standard.

Technical Specification of QM-5000


QMaster 5 Demo [Instalátor, EXE soubor]
Free demo version of the QMaster application. The application is fully functional for 10 days after the instalation. Then the functionality of the program is restricted: the program runs only for 10 minutes after the execution, the frequency spectrum analysis is limited to 110MHz. Note: This version allows to install example data recorded by the application in a real QM-5000 system. This data can be browsed and manipulated even without other elements of the system (QMI/QME interface, MRA/DMC devices).
