110 RF Detector
ST110 Professional RF detector
ST110 is designed for detecting and locating of radio transmitting bugging devices, such as:
Radio microphones, Including Burst transmitters, and devices with frequency hopping technology
GPS TRACKER
GSM bugs
Wireless video cameras, stethoscopes
Unauthorized used WLAN and DECT devices
Key features
Separate indication of analog and pulse signals
Displaying of identified signals of GSM (2G), DECT, WLAN (2.4GHz)
Frequency meter
Oscilloscope
Timing diagram
Special software “ST110 ANALYZER”
Firmware update via internet
24/7 monitoring
Log of events
Principle of operation of ST 110 is based on broadband detection of electrical field
ST 110 operates in two main modes: SEARCH and MONITOR.
Additional modes include: LOG VIEW, OSCILLOSCOPE and RECORDER.
SEARCH MODE
This mode is intended for search and detection of RD. Usage of this mode is based on visual estimation of signal level on 32-segmental scale. Additionally separate indication of continuous and pulse signals, identification signals of GSM, DECT, BLUETOOTH, WLAN standarts and stable signal frequency are used.
The possibility of acoustic control by means of headphones is provided.

MONITOR MODE
This mode is designed for independent operation of ST110 on preset conditions. The information about detected
signals is saved by means of non-volatile memory of the device (9 banks, each for 999 events).
Scheduled work operation is also provided.
