SZMID - MDPB-S105 (Audio Recorder Jammer): Advanced Acoustic Interference for Confidential Information Protection
The SZMID MDPB-S105 is an advanced audio recorder jammer designed to provide comprehensive protection against unauthorized recordings in sensitive environments. By emitting random acoustic signals, this device disrupts the speech signal, ensuring that digital recording equipment captures only noise and cannot distinguish the original voice. The randomly generated interference sequences make it impossible to restore the original information from the recorded audio, guaranteeing the confidentiality of voice communications.
This product is specifically designed for use in environments where confidentiality is paramount, such as government offices, courts, military facilities, public security sectors, and other industries handling sensitive business information. The MDPB-S105 is powered by a self-developed FPGA-based ultrasonic noise algorithm, delivering superior anti-recording performance by effectively interfering with mobile phones, voice recorders, and other digital devices. It ensures that conversations remain secure, preventing the risk of unauthorized recordings.
The device offers a broad protection range, forming a safe conical space of approximately 15 square meters, with an interference distance of over 2 meters for most mobile phones and recording devices. This creates a secure environment where users can have confidential conversations without the worry of being recorded.
Extensive testing has demonstrated the MDPB-S105’s effectiveness across a wide range of devices, including iPhone, Huawei, Xiaomi, OPPO, VIVO, and Samsung smartphones, as well as recorders from brands like SONY, Olympus, and Lenovo.
One of the standout features of the MDPB-S105 is its quiet operation. The sound waves emitted are only detectable by digital recording equipment, while remaining inaudible to people. This ensures discreet protection, making the device ideal for securing confidential meetings and conversations without drawing attention to its presence.
