As the recording capabilities of smart phones and voice recorders have greatly improved, they are highly concealable. Many times we are recorded by people with ulterior motives without our knowledge. Some people even go to bathhouses or other places to discuss business. In the swimming pool... Recently, the editor of Jun'an Siwei has received the most asked questions from netizens: Is there a recording jammer? How does it work? What are the better anti-recording jammers?
The principle of the anti-recording jammer is to produce suppressive interference to the voice signal through random sound wave signals, so that the digital recording equipment only has noise information and cannot distinguish the voice signal. Through randomly generated sequences, the original information cannot be restored from the recorded signal, thus ensuring the security of voice information. This product only blocks recordings from mobile phones and voice recorders.
Its core technology has two parts. The first is an advanced algorithm and chip that can randomly generate ultrasonic waves that run for tens of thousands of years without repeating; the second is a military-grade ultrasonic generator.

1Imported portable recording jammer Notebook-24
Portable recording jammer Notebook-24 interference type: interference through ultrasonic waves. Jamming nearby recording equipment in three directions prevents visitors sitting next to and across from the table from secretly recording. At the same time, the device user can use recording equipment to record the conversation on the side without the transmitter.
The device should be placed so that the transmitter points directly to possible locations where recording/eavesdropping equipment (recording pens, mobile phones, microphones, eavesdroppers, etc.) may exist. The optimal distance from the transmitter to the recording equipment is within 2 meters. Users should also talk in a low voice while protected by the device, so the effect will be better.

signal jammer
The "DAudio BDA-2M BDA-3 (Expander Type)" anti-recording and eavesdropping jammer produced in Russia can solve your worries. The anti-recording and eavesdropping jammer is a portable, highly integrated security protection device that integrates ultrasonic interference and voice sound wave interference. It can effectively interfere with digital analog recordings such as recording pens, mobile phone recordings, and tape recordings, and interfere with wireless eavesdropping and wired eavesdropping. Various voice eavesdropping devices such as wall eavesdropping, laser eavesdropping, etc. can make the conversation sound obtained by the eavesdropper unable to identify, thus effectively protecting your privacy.

This device supports external ultrasonic transmitters, which can achieve multi-directional and multi-angle interference and shielding recording equipment, achieving almost 100% shielding effect against eavesdropping and recording equipment.
3: Small conference room anti-recording interference jammer
The ultrasonic suppressor 24-avto is specially designed to protect conversations in the car from eavesdropping and is equipped with 24 ultrasonic transmitters. The device blocks wireless bugs, tape recorders, radio frequency bugs, wired bug recorders and most professional/digital tape recording devices (such as recorders), as well as recorders including smartphones.

Effectively prevent eavesdropping and video recording. Protect confidential conversations, car business negotiations, and prevent eavesdropping. The device mounts to the car ceiling using powerful magnets. Therefore, the ultrasonic emitters are pointed downwards to the sides, ensuring protection of the entire space below (360 degrees). You can guarantee that you won't record them on any type of audio recorder. The built-in battery provides 60 minutes of autonomous protection.
