MDPB-L7S

The SZMID - MDPB-L7S operates by emitting ultrasonic waves combined with random noise, imperceptible to the human ear. This noise interferes with digital recording devices, such as mobile phones and audio recorders, ensuring that any attempts to capture conversations result in unusable audio. By mixing these ultrasonic waves with regular speech, the device makes the captured audio irreparable, preventing any recovery or restoration of the original conversation. The same interference applies to the audio in recorded videos, making this jammer highly effective in safeguarding sensitive information.

Equipped with a cutting-edge FPGA-based ultrasonic noise algorithm, this device provides robust anti-recording capabilities. It effectively disrupts a wide range of digital devices including mobile phones, recording pens, and other equipment, ensuring that conversations are protected from being captured or leaked. The protection zone spans approximately 15 square meters in a conical shape, with interference reaching up to 2.5 meters for most mobile phones. This creates a secure environment where users can confidently engage in conversations without fear of being recorded.

SZMID - MDPB-L7S has been extensively tested on various mobile phone models, including iPhone, Huawei, Xiaomi, OPPO, VIVO, Samsung, and more. It has also been tested on numerous audio recorders, with excellent results. Unlike many other jammers, the SZMID - MDPB-L7S operates quietly, producing no buzzing noise. This ensures that conversations are not only secure but also discreet, as the device's activity is undetectable to those nearby.
