SZMID - MDPB-L7C (Recording Device Jammer): Advanced Ultrasonic Anti-Recording Technology for Secure Conversations
The SZMID MDPB-L7C is a highly effective recording device jammer designed to protect private conversations by emitting ultrasonic waves and random noise that cannot be perceived by human ears. This ultrasonic interference disrupts the microphones of digital devices, such as mobile phones and voice recorders, by embedding the noise into the recorded audio, rendering it unusable. As the noise is generated randomly, the recorded audio cannot be restored, ensuring that sensitive information remains confidential and is not leaked or transmitted.
In addition to its anti-recording functionality, the MDPB-L7C also serves as a portable power bank, offering dual functionality and strong concealment in a sleek, everyday device. The jammer is equipped with a wireless sensor that allows users to remotely control the device from distances of 1-20 meters, providing convenient on/off functionality at the push of a button.
Powered by a self-developed FPGA-based ultrasonic noise algorithm, the MDPB-L7C offers superior anti-recording capabilities, effectively interfering with the recording functions of a wide range of devices, including mobile phones, digital voice recorders, and other audio recording equipment. The device creates a protective zone with a conical interference range of approximately 15 square meters, ensuring that within a radius of more than 2 meters, recording devices are rendered ineffective. This forms a secure environment, free from the risk of unauthorized recording.
The MDPB-L7C has been rigorously tested on a variety of mobile devices, including iPhone, Huawei, Xiaomi, OPPO, Samsung, and other popular brands, as well as digital recorders from SONY, Olympus, and more. The results demonstrate excellent interference performance across both new and older models, ensuring wide compatibility and effectiveness.
One of the standout features of the MDPB-L7C is its quiet operation. Unlike other anti-recording devices that produce audible buzzing sounds, the ultrasonic waves emitted by this device are only detectable by digital recording equipment, leaving the human ear undisturbed. This ensures that conversations are discreetly protected without drawing attention to the jammer's operation, making it an ideal solution for safeguarding confidential discussions in any environment.
