Phone Shielding Device 2-10m

• 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.

• 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 Operates under fully autonomous intellectual property rights, from design and manufacturing to production and after-sales, ensuring full control and reliability.

• Fixed Ceiling Installation Installed at the top of indoor spaces to save space and remain concealed (the appearance resembles a ceiling speaker, providing excellent concealment without drawing undue attention).

• 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.

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.
