AAT-SJ-N9 recording jammer is an anti-recording equipment based on ultrasonic interference technology. The device generates ultrasonic waves to interfere with various recording devices in the coverage area, making it unable to record normally, recording noise, and unable to restore the original sound data.
AAT-SJ-N9 is a desktop installation form of equipment, mainly covering the space below the desktop, to ensure that the recording equipment within this range cannot record normally. The device can support angle adjustment, installed under the table, and can adjust the angle according to the position of the interfered target to achieve a better shielding effect.
Turn on the switch button, and the anti-recorder will emit ultrasound that exceeds the threshold of human hearing and is harmless to humans. Using our self-developed ultrasonic noise algorithm, the microphones in mobile phones, voice recorders and other digital devices will be affected by the anti-recorder, so that the sound of normal conversation is submerged in random noise, and the post-recording processing algorithm is also difficult to restore. So as to protect the content of the conversation from being leaked from the source.
