MDPB-L7S sound Audio Jammers

• 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.
