Product Details

BUGHUNTER BDA-4 ULTRASONIC RECORDER JAMMER

BugHunter BDA-4 ultrasonic dictaphone jammer is a discreet device that is used to block audio recording during negotiations or meetings. It is a very quiet jammer, which in its design resembles a modern speaker. It is equipped with 8 ultrasonic transmitters, thanks to which it is able to suppress all eavesdropping devices (microphones, including laser ones, voice recorders, including professional ones, smartphones, etc.). To increase the range, the jammer can be switched to audible jamming through the acoustic speaker. 

BDA-4 generates a very strong ultrasonic signal (at least 125 dB), which spreads according to a specially developed algorithm and jamming microphones at a distance of 1 to 7 m from the device. The device is powered by a 110/220V mains, which ensures maximum interference performance.

KEY PROPERTIES:

  • Discreet appearance of a regular speaker
  • A unique combination of ultrasound and white noise
  • 8 ultrasonic transmitters 
  • Audible (acoustic) interference option for increased range with adjustable volume
  • Range up to 7 meters
  • Consumption 0.7A
  • Dimensions 180 x 165 x 110 mm
  • Weight 2kg

The jammer combines two forms of interference: ultrasound (frequency range over 20 kHz) and acoustic sound (frequency range 18-19 kHz) similar to human speech. Both signals intertwine and create strong interference from 40-60 cm from the device.
Human-speech-like interference, or so-called "white noise," turns the recording of your conversation into an indistinct set of sounds. Restoring or cleaning a recorded conversation is physically impossible even on professional devices. White noise is audible to the human ear, but in return you get 100% confidence that your actions are confidential.
On the back of the device there is a control for adjusting the volume of acoustic interference. You can simply turn off the acoustic interference by turning the knob to the minimum, and the device will then generate only an ultrasonic signal.

EASY TO USE ULTRASONIC JAMMER

Using the jammer is very easy. Just plug it in and turn on the ultrasonic interference. By turning the switch on the back, we can also activate an additional mode that increases the effectiveness of interference, but is already audible. Ultrasonic transmitters are directional, so it is necessary to point them in the direction where you expect the recording device to be located. 

 

Warning:
The ultrasonic jammer produces noise with a volume of 125dB at a distance of 1m from the device. Never play a jammer near someone's ears. Although the ultrasound cannot be heard, there is a risk of hearing damage.
