ST-500 PIRANHA

The multifunctional detection device ST 500 "PIRANHA" is intended for the detection and location of eavesdropping devices. Functionally, the device consists of four detection channels.

Channels for the detection of wireless eavesdropping devices:

·         SELECTIVE HF DETECTOR is intended for the detection of analog and digital wireless (utilizing GSM, LTE, Bluetooth, or WiFi) eavesdropping devices operating in the frequency range 20 - 6000 MHz.

·         IR DETECTOR is intended for the detection of IR transmitters (eavesdropping devices using the infrared range for transmissions).

Channels for the detection of wired eavesdropping devices:

·         WIRED RECEIVER is intended for the detection of high-frequency signals from eavesdropping devices that transmit information via electric mains and low current lines in the frequency range 100 kHz – 180 MHz.

·         LOW FREQUENCY AMPLIFIER is intended for the detection of LF signals from eavesdropping devices.

Functionality of the device:

1. Detection and location of radio eavesdropping devices:

·         radio microphones, telephone radio repeaters, radio stethoscopes, etc.

·         video cameras with radio transmitters

·         radio beacons of tracking systems.

2. Identification of digital protocols of the detected radio signals: GSM, CDMA, Bluetooth, LTE, WiFi.

3. Identification of signals of base stations and mobile digital communication devices.

4. Detection and location of active wired eavesdropping devices:

·         wired microphones transmitting through permanent and makeshift low current lines

·         detection of signals from eavesdropping devices transmitting over electric mains and low current lines in the frequency range from 0.1 - 180 MHz.

5. Activation of wired electret microphones by applying a bias voltage to the circuit

6. Detection and location of eavesdropping devices that utilize infrared transmissions.
