Microphone, listening device and voice recorder suppressor "BugHunter DAudio BDA-4 PRO"

New product! Compact stationary microphone, listening device and voice recorder suppressor BugHunter DAudio BDA-4 PRO with 16 powerful ultrasonic transducers. The unique suppression system with the formation of sound interference in the air, effectively affects protected microphones (with protection rating IP65-68) and voice recorders with AI filters of sound interference.

The device is completely stationary, powered by a 12V power supply (or battery). The device is equipped with a remote control, which allows to control it from a distance up to 98 ft (30 m). Several devices (from 2 to 8) can be combined into a powerful suppression system with Wi-Fi control (Smart life - a popular application for smart home).

Compact stationary microphone suppressor BugHunter DAudio BDA-4 PRO

Advantages:

• Dense broadband ultrasound-interference in the air – effective against modern digital voice recorders and microphones with a degree of protection built into mobile phones and with AI filters.
• Wide opportunities – supports combining multiple devices into a single system, remote control, and operates in a wide frequency range. An array of 16 transducers forms a uniform field in the negotiation area.
• Compact and unobtrusive – the laconic design with acoustic fabric looks organically on the table without attracting too much attention.
• Ready to work «out of the box» – mains power, two remotes, simple one-button operation.

The microphone and voice recorder suppressor is ready to work right "out of the box"

How does it work?

The professional new generation microphone and voice recorder suppressor BugHunter DAudio BDA-4 PRO is designed specifically to protect the meeting place from recording devices. Blocks ANY radio microphones, wired microphones, and most professional digital voice recorders, including voice recorders in mobile phones (smartphones) within a radius of 1,6 to 29 ft (0,5-9 m) (depending on the protection degree of the voice recorder).

The device generates an ultrasonic signal using 16 built-in transducers with random frequencies of 28-40 kHz. The ultrasound frequency is set by the microcontroller and changes according to the specially developed copyright algorithm (for maximum suppression efficiency). The combined ultrasonic signal generated by the device affects the recording microphones of listening devices (voice recorders, cell phone microphones, etc.). This overloads the microphones across a wide frequency range. The microphones do not stop working but start recording random sounds, making it impossible to comprehend the conversation, or they cease recording altogether. As a result, the recorded speech becomes unintelligible and completely unrecoverable.

The suppressor BugHunter DAudio BDA-4 PRO affects even protected microphones and voice recorders with AI filters of sound interference.

Unique suppression system: ultra-high frequencies + variable interference

"BugHunter DAudio BDA-4 PRO" has received a new super powerful suppression system:

• Ultra-high frequency ultrasound mode. Ultrasonic interference consists of several frequencies in the range from 28 to 40 kHz simultaneously. An analog of an audio signal is formed in the air, which forces voice recorders with AI to record interference.
• Powerful ultrasound with variable interference. Ultrasonic interference is generated in an random order, which does not allow AI to adjust to their cropping, even the «smartest» voice recorders perceive interference as normal sound. As a result, the record is unreadable and cannot be decrypted.

Powerful sound suppression system: up to 8 devices simultaneously!

If a high level of protection is required, you can purchase multiple devices and combine them into a single sound suppression system to control all connected devices SIMULTANEOUSLY. A total of 2 to 8 devices are supported. At the same time, devices can be used at different levels for maximum suppression and impact on all possible zones. The devices can also be directed at the walls, providing protection against the new mmWave method of information capture. This method of recording information uses microwave radars that penetrate walls. To manage the created system, you can use the popular smart home application "Smart life".

How to achieve maximum efficiency?

• If possible, choose a square room with a ceiling height of no more than 11,4 ft (3,5 m) for negotiations, since ultrasonic interference is reflected in such rooms, creating additional suppression power.
• Point the front panel at the intended recording source: the visitors' side, the meeting table, the entrance area.
• In rooms with reflective surfaces, the effect is enhanced by repeated reflections of ultrasound. In large rooms, it is advisable to use several appliances for uniform coverage.
• For complex scenarios (for example, aggressive AI filters or attempts to capture speech via vibro or radar methods through barrier structures), turning some of the transducers towards the walls helps: this increases the level of acoustic vibrations in the surfaces and complicates speech recovery further.

Note! The strongest suppression effect is achieved by combining BDA devices, for example, BugHunter DAudio BDA-4 PRO and BugHunter DAudio BDA-4. This creates the most intense interference for recording when using devices equipped with AI filters.

Security

"BugHunter DAudio BDA-4 PRO" is absolutely safe for people, as it generates sound frequencies that are practically imperceptible by ear. However, it should be taken into account that the collision of ultrasonic frequencies causes sound pops in the air. The ultrasound power reaches record values of 125 dB. This means that the level of ultrasonic pressure at a distance of less than 3,3 ft (1 m) from the switched-on product may exceed the maximum permissible emission level safe for humans.

Follow the security measures:

• Do not point an operating device at a person's ear.
• Pets are often sensitive to ultrasound, do not use the device in their presence if possible.
• Do not cover the front panel or damage the transducers, as this reduces efficiency.

Technical specifications:

• Effective (maximum) range of suppression the eavesdropping devices – up to 23 ft (7 m)
• Effective (optimal) range of suppression the eavesdropping devices – up to 7 ft (2 m)
• Sound pressure level at 3,3 ft (1 m) distance from the device – at least 124 dB
