ST-500 PIRANHA Multifunctional RF Detection Device

$12,985.00

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.

Distinctive features:

Detection and location of radio eavesdropping devices
Identification of digital protocols of the detected radio signals: GSM, CDMA, Bluetooth, LTE, WiFi
Identification of signals of base stations and mobile digital communication devices
Detection and location of active wired eavesdropping devices
Activation of wired electret microphones by applying a bias voltage to the circuit
Detection and location of eavesdropping devices that utilize infrared transmissions

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.

This device is incredibly powerful! The RF detection range is impressive, covering 20-6000 MHz, and it picks up even the most discreet signals. The infrared detection is a fantastic addition, making it easy to spot hidden transmitters. The interface is intuitive, and the wired signal analysis ensures nothing slips through. If you need professional-grade counter-surveillance, this is the tool to get!
