Advantages

What it is: a portable system controlled by a laptop computer
    
  • The high capacity of a laptop’s hard drive enables full data logging during the detection (24/7 possible)
  • Wider screen is more convenient for analysis
  • Compatible with touch screen laptops
  • The handheld use of antennas is more convenient for locating transmitters in hard to access places
 
Handling of the mobile and wireless bands GSM, CDMA, 3G, 4G/LTE, DECT, Wi-Fi, Bluetooth, etc.
    
  • Mobile and wireless signals are detected simultaneously with analog transmissions
  • Mobile/wireless signals are detected with the use of individual thresholds and are displayed separately from other signals
  • Activities within each band are stored as one signal with a certain danger level to avoid excessive records in the Signals table and to locate the sources with a hopping frequency
  • Additional sweepings on the "short-burst" bands are performed to increase the probability of interception of such signals as GSM, 3G, 4G, DECT, Wi-Fi, Bluetooth, etc.
  • External interference from neighboring mobile phones and Wi-Fi routers can be rejected with the help of the thresholds
  • The supplied data files allow the operator to adjust the system to the mobile/wireless bands employed in the country of use
 
Sensitivity and detection distance
    
  • The built-in spectrum analyzer has 20-50 times higher sensitivity and detection distance compared to conventional RF detectors and near-field receivers
  • Resistant to interference - sensitivity remains high regardless of the proximity to wireless routers, cordless phones, mobile phones, TV towers, radio broadcasting and mobile communications
 
Support of the "Known signals" table
    
  • The operator can easily distinguish between safe and dangerous signals
  • The TV frequencies employed in the country of use can be quickly imported from the supplied data files
  • The FM, VHF/UHF police and municipal channels can be collected and stored for further us
 
Advanced signal recognition method
    
  • The signals are automatically recognized in the spectrum traces and inserted or updated in the Signals table
  • Both analogue and digital signals are captured with an assigning of a corresponding Danger level
 
Unique algorithm of measuring the signal's Danger level
    
  • Uses a combination of the reference trace and individual thresholds for mobile/wireless bands
  • Takes into consideration both the signal's strength and bandwidth
  • Works for both analogue and digital signals including transmissions with a changing frequency
  • Is used during the locating procedure and provides more reliable results compared to the traditional "signal strength" method.
 
Low demands on the operator's level of knowledge
    
  • The system can be prepared for detection with the help of the "Update Masks" procedure within a few minutes
  • Manual handing of spectrum traces is not necessary
  • Everything is done automatically after the detection starts
  • The operator is warned by an audio alarm when a dangerous signal is detected
 
Data logging
    
  • All the spectrum traces and alarms are logged during detection
  • The situation at any given time can be reviewed and studied
  • 24 hours a day logging provides detection of periodically working/remotely controlled bugging devices
 
Tracking of the signal's activity
    
  • The full history of each separate signal, or of all signals simultaneously, is displayed on the Alarms graph
  • The events at any given time can be reviewed by simply clicking on the graph
  • The operator can see the duration of an activity and as such distinguish between any interference and real danger
 
The Waterfall and Persistence graphs
    
  • Both the present and previous measurements at any given time can be displayed
  • The displayed time interval (density) is selectable in the range of 2 minutes to 6 hours
 
Car Tracker Detector mode
    
  • The monitoring of mobile bands can detect signals from GPS trackers hidden within a vehicle

Functions of the software

  • Rich visual representation: Spectrogram/Persistence, Waterfall, Alarms graph
  • The Known Signals table allows the system to reject TV, FM and other "friendly" signals while maintaining high sensitivity to unknown signals.

  • The Alarm Threshold decreases the false alarm rate
  • The Hold Max Danger feature selects and shows the strongest signals for their location as the system is moved during detection
  • The Update Mask procedure allows the operator to quickly adjust the system to the local RF environment in order to reject safe signals

Working modes

  • Stop/View Log
    Review of the detection results stored in the log. The Signals table, Spectrogram, Waterfall and Alarms graph give full information about the detected signals and alarm events
  • Update masks
    Quick preparation for detection – the system automatically accumulates the broadcasting and other safe signals existing in the area in order to pass over them during the subsequent detection
  • RF Sweep
    The main detection mode. Provides maximum reaction time and the highest sensitivity. The operator can move the system or its antenna during the detection.
  • Guard 24/7
    Rejection of short transmissions and usage of two antennas reduces false alarms in this mode. Suitable for 24 hour detection without unwanted false alarms
  • Car Tracker Detector
    Detection of vehicle mounted GPS trackers transmitting the coordinates via mobile networks
  • Probe
    Checking of AC, Ethernet, Telephone and Alarm wires and the infrared/low frequency for the presence of unwanted bugging signals
