Wireless Remote Control Shielder 1-20m

• Measured Shielding Range of 1-5 Meters The shielding range for Apple phones is approximately 1 meter, while Android phones have a shielding range of 4-5 meters.

• Ultrasonic Interference Technology Based on the reflective properties of ultrasonics, this technology can interfere with microphones in recording devices, rendering recordings ineffective. 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 The device operates under fully autonomous intellectual property rights, from design and manufacturing to production and after-sales, ensuring full control and reliability.

• 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.

• 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 1-20 meters.

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

Large scope: 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 of most mobile phones and other digital products is more than 2 meters, which can form a safe space, and there is no need to worry about being recorded by others in this space;

Many 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 issued by the anti-recording device are only received by mobile phones, recording pens and other digital products, but the sound that people can not hear is not buzzing noise compared with other anti-recording devices, and the quiet guardian conversation environment is not easy to be detected.
