1. GENERAL INFORMATION
This user manual describes the composition and operation of the multifunctional detection
device ST 500 "PIRANHA". The information contained in this manual is cross-referenced with
hyperlinks.
1.1. PURPOSE AND CAPABILITIES
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.
