Description

Microphone Suppressor Blocker Anti Spy BugHunter BDA-2 Ultrasonic Leather Bag
Upgraded model features new design and improved jamming system (invented specifically for concealed operation). Unlike the predecessor model "BugHunter DAudio BDA-2 Voices", the new model generates a completely different ultrasonic interference intended for jamming the newest smartphone models with moisture protection and noise cancellation. By virtue of new jamming system, the device is capable of jamming any kind of eavesdropping device: professional dictaphones (E-dic Mini, Gnom, Soroka etc.), radio microphones, cell phones, wired, wireless and directional microphones.
Distinctive features:
1) Absolutely silent operation.
The new model is equipped with ultrasound transducers only and doesn't have built-in audio speaker for speech-like interference. Operating device does not reveal its work that allows you to use it unnoticed by others.
2) There is no Turbo mode.
"BugHunter DAudio bda-2 Ultrasonic" operates on a different frequency than "BDA-2 Voices", therefore it does not require "Turbo" mode — it always suppresses eavesdropping devices with maximum effectiveness.
3) Completely updated suppression system.
The device generates completely different ultrasonic interference which is designed to suppress even the newest smartphones with moisture protection and noise cancellation.
Carry and operate inside a high-quality leather case
"BugHunter DAudio BDA-2 Ultrasonic" always operates in maximum effectiveness mode, previously called Turbo. It only takes one press of a button to start its operation.
The new model operates at a different frequency compared to "BugHunter DAudio BDA-2 Voices" thus it does not require additional Turbo mode, it perfectly jams eavesdropping devices with maximum efficiency. Another advantage of the device is that it operates absolutely silently as ultrasound is not perceived by human ear. It is equipped with rapid switch-on button.
Capability to connect acoustic speakers to create a "sound shield" for protection from laser microphones instead of buying special window blinds that are rather expensive.
"BugHunter DAudio BDA-2US" emits ultrasound interference not only directionally, but also side-wise thus jamming recording devices located aside of the device. Such device has no equivalents!
By using two or more devices, you can create a mini system for protection from eavesdropping.

3) Completely updated suppression system.
The device generates completely different ultrasonic interference which is designed to suppress even the newest smartphones with moisture protection and noise cancellation.
Competitive advantages:
1) Assured protection. It suppresses most of the spy devices with microphones.
The device is designed for mobile and inconspicuous use when only ultrasonic interference is used.
It is able to suppress all types of microphones (smartphones, professional recorders like Soroka, Gnom, Edic, etc.) located in the action range of its transducers.
2) High suppression power and action range.
The device emits very powerful ultrasonic signal (not less than 120 dB).
There are no equivalents that can compete in power and range with this device in the Russian market.
It suppresses microphones at a distance of up to 7 m (23 ft).
Most counterparts, especially Chinese ones, perform at least 2-3 times worse.
The emission power of the device is so high that our experts do not recommend bringing its transducers close to the hearing organs in order to avoid injury.
3) Capability to suppress microphones located on the side of the suppressor.
The suppressor generates not only a directed wave of ultrasound, but also a scattered wave that spreads to the sides of the transducers.
It means that the interference signal will affect smartphones or dictaphones in the wider sector, capturing space on the side of the transducers.
There is a high probability of suppressing spy devices which the suppressor is not directed to.
4) Capability of connecting external acoustic speakers to protect large rooms and/or suppress directional microphones.
You can output speech-like interference to external speakers (such as computer speaker system) via the jack located on the front end of the device.
This will help you to protect very large rooms from eavesdropping.
In addition, external acoustics will make useless even directional microphones (for example, laser ones).
This will save you money on the installation of special vibration window blinds.
6) Mobile and stationary use
"BugHunter DAudio BDA-2 Ultrasonic" operates equally well from two power sources:
110/220V power mains (connection via the supplied charger) and built-in battery, with capacity of 2600 mAh.
Its charge is sufficient for a few hours, wherever you go, the suppressor will always be with you ready to protect you from the spies.
When you have access to electrical mains, you can simply connect the device to it.
Thus, the device can be portable and stationary depending on the circumstances.
Operation principle
The device generates ultrasonic signal with a help of 5 built-in transducers.
The frequency of ultrasound is set by the microcontroller and it changes in accordance with a specially developed algorithm for maximum suppression.
Ultrasonic signal generated by the device affects the recording paths of eavesdropping devices (dictaphones, microphones of cell phones, etc.), so that they record only indistinct noise, making it impossible to distinguish any details of the conversation.
The device has a jack for connecting external acoustic speakers.
Speech-like interference is transmitted through the speakers thus defacing the meaning of the conversation.
Therefore, eavesdropping devices record only unintelligible mumbling and it is physically impossible to restore the conversation.
Speech-like interference is generated randomly, so you can not filter it even with a help of a special equipment.
This complex protection ensures the highest possible reliability and confidentiality.
Any spy devices with microphones (even the most expensive) turn into completely useless "toys", because they simply can not record necessary information.
At the same time interference does not militate negotiations as ultrasonic signals are not perceived by the human ear and the volume of the speech-like signal is easily adjusted.
You and your interlocutor will hear each other perfectly, but nobody will be able to overhear your conversation!
Operation
It's very simple, no settings are required. Simply point the suppressor's transducers in the direction of assumed eavesdropping devices, and turn it on by pressing the button located on the lower end of the device's housing.
Note that you can make the protection even more reliable by using several suppressors and directing them to eavesdropping devices from different sides. For instance, ultrasonic interference from a single suppressor would not be sufficient to suppress recording on smartphones with moisture protection (iPhone 8+ and higher, Samsung Galaxy S10, etc.). In this case, using two or more devices at the same time is the best solution.
Before using the suppressor we recommend to:
1. Check the battery level if the device is operating autonomously.
2. Conduct a small test of the device performance.
You can use the voice recorder on your cell phone for testing. Turn the suppressor on, point the transducers at the cellphone and start talking. Then listen to what the cell phone recorded. There should only be unintelligible noise on the recording. If so, the device performs properly.
