With the development of the information society, audio and video information has two remarkable characteristics: explosive growth and viral spread. Personal privacy, business secrets and other information are at risk of being leaked through conversations, especially how valuable conversation information can protect conversations Content is not stolen by others? . The Watergate Incident and the Recording Door Incident reflect the demand for anti-recording products in the current environment. At present, there are many types of anti-recording and eavesdropping products at home and abroad. Most of them are interfered by white noise. Although there is a certain interference effect, it is also a kind of noise pollution for all parties involved in the conversation, and even affects the body of the conversation personnel. healthy.
AL ASAR TECH has been in information security for 14 years. The newly developed AAT-ER-360 360 ° three-dimensional ultrasonic audio jammer has been re-upgraded on the basis of the original equipment. The FPGA-based ultrasonic band noise algorithm eliminates the high-frequency noise of the old equipment. It has collected information on various brands of mobile phones and recording equipment that have been listed in the past two years, and has a very obvious effect on the new recording equipment and mobile phone recording. It is suitable for confidential meeting rooms, public security bureau petition center, procuratorate reception hall, court court, negotiation room, office and other places where private conversations are held.
The principle of the recording jammer
By emitting ultrasonic waves with random noise that cannot be perceived by the human ear, when a digital device such as a mobile phone is recording, these noises are recorded into the digital device together with the sound of normal conversation, making the recorded audio invalid. Audio information also has the same interference effect. Since the ultrasonic noise is randomly generated and cannot be restored, the disturbed audio cannot be restored, thus ensuring that the original information is not leaked and spread.
Recording Jammer Features
High interference intensity: Our self-developed FPGA-based ultrasonic noise algorithm can effectively interfere with digital devices such as mobile phones and voice recorders, record noise, and completely eliminate the harsh sound that a few people can hear.
Long interference distance: The anti-recording device can interfere with 95% of mobile phones at a distance of more than two meters, 60% of mobile phones with a distance of more than 5 meters, and interfere with iPhone X, iPhone 8 and other mobile phones within 10 meters, which can effectively protect conversations content
Many interference devices: good interference effect on various mobile phones such as iPhone series, Huawei mate, Honor, OPPO, VIVO, Samsung, Nubia, Meizu, Nut, etc. Recording pen test interference effect is good
Quiet at work: The anti-recording device replaced the ultra-quiet fan, and the sound when working is smaller and quieter than the old device.
