SZMID - MDPB-L7 Voice Jamming Device: Ultimate Protection Against Audio Leaks
In today’s information-driven society, the rapid growth and viral spread of audio and video content put personal privacy and sensitive business information at constant risk. The SZMID - MDPB-L7 voice jamming device provides a powerful solution for preventing unauthorized recordings of valuable conversations. It works by emitting ultrasonic waves combined with random noise that is inaudible to the human ear but effectively disrupts digital recording devices such as mobile phones and voice recorders. These random ultrasonic waves are recorded along with normal conversation, rendering the captured audio irreparable and useless, ensuring the conversation is secure and cannot be leaked.
The SZMID - MDPB-L7 uses an advanced FPGA-based ultrasonic noise algorithm to achieve a highly effective anti-recording performance. Tested across a wide range of devices—including iPhone, Huawei, Xiaomi, and other popular phone models—the jammer provides exceptional results, blocking recordings from both new and older models. The interference range covers up to 15 square meters, creating a safe, conical space where sensitive discussions can take place without the risk of being recorded. With an interference distance of over 2 meters, it ensures comprehensive protection for mobile phones and other digital recording devices.
One of the standout features of the SZMID - MDPB-L7 is its discreet operation. Unlike other jammers, it does not produce a buzzing noise, maintaining a quiet environment while still actively guarding against recording attempts. The device is designed for ceiling installation, blending in with indoor spaces by resembling a regular ceiling speaker, making it both practical and unobtrusive.
