Is there a device to block recordings? "Recording blocker is the first security protection product that uses the world's leading acoustic interference technology, from the inside to the outside, from hardware to software, to shield all kinds of recording equipment, and to provide multiple protections for voice messages. This series of products can protect against All kinds of recording equipment (and video recording equipment) such as mobile phones, voice recorders, and eavesdroppers perform recording shielding, so as to solve the problem of voice information leakage caused by illegal recording.
The recording blocker emits ultrasonic waves with random noise that human ears cannot perceive. When recording digital devices such as mobile phones, these noises are recorded into the digital device together with the sound of normal conversations, making the recorded audio invalid. The audio information in the video also has the same interference effect. Since the noisy ultrasonic noise is randomly generated and cannot be restored, the audio after the interference cannot be restored, thus ensuring that the original information is not leaked and spread.
Product advantages
(1) Good shielding effect
The recording shielding device can shield various recording equipment such as mobile phones, voice recorders, and eavesdroppers. Its shielding performance ranks first among similar products at home and abroad, far surpassing other products. The radial shielding distance of this product is about 2 to 4 meters, and the shielding angle is about 120 degrees.
(2) Multi-point deployment control
According to the on-site environment, a multi-point deployment control method can be adopted. In the area where recording is required to be shielded, an audio recording shielding device can be placed to realize the recording shielding of the entire application scene.
(3) Strong concealment
This product adopts an audio-style design, its appearance is almost the same as the audio, and it is extremely concealed, which is not easy to cause the detection of the thief, and can effectively prevent the leakage of voice information.
(4) No harm to human body
This product adopts the acoustic interference mode, breaking through the electromagnetic interference bottleneck of traditional recording shielding equipment. There is no electromagnetic radiation when the product is working, so it will not cause harm to the human body.
