  • The 66 recording shield product produces suppressive interference to the speech signal through random acoustic signals, so that the digital recording equipment only has noise information, but can not distinguish the voice signal. Through randomly generated sequences, the original information cannot be restored from the recorded signal, thus ensuring the security of voice messages.

• Measured Shielding Range of 1-5 Meters When a microphone is directly facing the shielder, the effective distance varies with different brands of smartphones and recording pens.

• Ultrasonic Interference Technology Based on the reflective properties of ultrasonics, this technology can interfere with the microphones in recording devices, rendering recordings ineffective. Additionally, it does not produce any buzzing noise.

• High and Low Frequency Sound Source Mixing Utilizes a process that mixes high and low-frequency sound sources, blending the original recording signal with the audio signal from the shielder. This makes the shielded recording unrecoverable in post-processing.

• Fully Autonomous and Controllable From design and manufacturing to production and after-sales, it operates under fully autonomous intellectual property rights. Completely self-controllable and reliable, meeting national policy requirements.

• Convenient Charging Model The device features a portable charging design, offering high mobility and independence from any terrain constraints, allowing for flexible deployment in all scenarios requiring protection.

• Multi-Angle Adjustable Independent Switches The device can independently control the switches of the four-sided combined emission terminals to meet the needs of different scenarios.

good anti-recording effect: our self-developed FPGA-based ultrasonic noise algorithm can effectively interfere with mobile phones, voice recorders and other digital equipment, the anti-recording effect is at the advanced level, and can effectively ensure that the conversation is not recorded, so as to ensure the security of information;

wide range: the protection range of a single anti-recording device is approximately a conical space, the interference range is about 15 square meters, and the interference distance for most mobile phones and other digital products is more than 2 meters, which can form a safe space, in which there is no need to worry about being recorded by others;

many active devices: We have tested iPhone, Huawei, Xiaomi, OPPO, VIVO, Samsung, Nubia, Meizu, Guan and other new and old models of mobile phones, the interference effect is good, the test SONY, Samsung, Newman, Lenovo, Olympus and other recorders, the interference effect is good;

Quiet guardian: the sound waves emitted by the anti-recorder can only be received by mobile phones, voice recorders and other digital products, but people can not hear the sound. Compared with other anti-recorder, there is no buzzing noise, and it can quietly guard the conversation environment is not easy to be noticed.

Measured Shielding Range of 2-10 Meters The shielding range for Apple phones is approximately 2-3 meters, while Android phones have a shielding range of 5-10 meters.

Wireless Remote Control Equipped with a wireless sensor remote control, it can remotely turn the device on and off, adjust the frequency of the shielder, with a sensing range of 1-10 meters.

When digital devices such as mobile phones record, these noises are recorded together with the sound of normal conversation into the digital device, making the recorded audio invalid. The audio information in the recorded video also has the same interference effect. Since the noise with ultrasonic noise is generated randomly and cannot be restored, the audio after interference can not be restored, so as to ensure that the original information is not leaked and transmitted.
