  • The laptop or tablet is attached with the help of magnetic holders.

  • Side handles are used for carrying.

  • All antennas are fixed to the main unit.

  • Carrying bag included in the set



✦ A portable system controlled by a laptop or tablet

  • The high capacity of the hard drive ensures full data logging during detection (24/7 possible)

  • Larger screen is more suitable for analysis

  • Compatible with touch screens

  • Magnetic holders ensure reliable attachment of the laptop/tablet to the unit, while side handles make it easy to transport the entire system

✦ GSM, CDMA, 3G, 4G/LTE, 5G(<6GHz), DECT, Wi-Fi, Bluetooth, etc. use of mobile and wireless bands.

  • With analog transmissions, mobile and wireless signals are detected simultaneously,

  • Mobile/wireless signals are detected using individual thresholds and displayed separately from other signals,

  • The activities in each band are stored in the Signals table as a single signal with a certain level of danger to avoid over-registration and find sources with skip frequency,

  • GSM, 3G, 4G, 5G(<6GHz), DECT, Wi-Fi, Bluetooth etc. Additional scans are performed on "short-term" bands to increase the probability of detecting signals such as

  • It analyzes the dirty and interference signals coming from the surrounding mobile phones and Wi-Fi routers accurately with the help of threshold level,

  • The data files provided allow the operator to adjust the system according to the mobile/wireless bands used in the country of use.

✦ Sensitivity and sensing distance    

  • The built-in spectrum analyzer has 20-50 times higher sensitivity and sensing distance compared to traditional RF detectors and near field receivers,

  • Interference resistant - sensitivity remains high regardless of proximity to wireless routers, cordless phones, cell phones, TV towers, radio broadcasts and mobile communications


✦ Support of "known signals" table    

  • The operator can easily distinguish between safe and dangerous signals,

  • TV frequencies used in the country of use can be quickly imported from the provided data files,

  • FM, VHF/UHF police and municipal channels can be collected and stored for further information.

✦ Advanced signal recognition method

  • Signals are automatically recognized in spectrum traces and added or updated in the Signals table,

  • Both analog and digital signals are captured by assigning a corresponding Hazard level.

✦ Unique algorithm to measure the Danger level of the signal    

  • Uses a combination of reference trace and individual thresholds for mobile/wireless bands,

  • It takes into account both the strength of the signal and the bandwidth,

  • It works for both analog and digital signals, including varying frequency transmissions.

  • It is used during the locating procedure and provides more reliable results compared to the traditional "signal strength" method.

✦ Ease of use and does not require high operator knowledge     

  • The system can be made ready for detection in a few minutes with the help of the "Update Masks" procedure,

  • Manual delivery of spectrum traces is not necessary,

  • Everything is done automatically after the detection starts,

  • When a dangerous signal is detected, the operator is warned with an audible alarm.

✦ Data logging    

  • All spectrum traces and alarms are logged during detection,

  • At any time the situation can be reviewed and examined,

  • 24 hours a day logging enables detection of periodically running/remotely controlled listening devices.

✦ Monitoring the activity of the signal    

  • The full history of each individual signal or all signals simultaneously is displayed in the Alarms graph,

  • Events occurring at any time can be viewed by simply clicking on the graph,

  • The operator can see the duration of an activity and thus distinguish between any intervention and real danger.

✦ Waterfall and Persistence graphics    

  • Both current and previous measurements can be viewed at any time,

  • The displayed time interval (intensity) can be selected from 2 minutes to 6 hours.

✦ Car Tracking Detector mod

  • Monitoring mobile bands can detect signals from GPS trackers hidden inside a vehicle

Software Features

  • Rich visual representation: Spectrogram/Persistence, Waterfall, Alarms graph

  • Known Signals cable allows the system to reject TV, FM and other “friendly” signals while maintaining high sensitivity to unknown signals.

  • Detector and Locator locate the operator's listening device and provide both visual and audible notification

  • Alarm Threshold ( "Alarm Threshold") reduces the false alarm rate

  • Hold Max Danger ( "Maximum Hazard Hold") feature shows the locations of selecting the strongest signal while moving during detection system

  • Update Mask ( "Mask Update") rejected the operator's procedures in order to secure the signal system allows to adjust quickly to the local RF environment
