SZMID - MDPB-L107 (Recording Device Jammer): Discreet and Effective Anti-Recording Solution
The SZMID MDPB-L107 is a state-of-the-art recording device jammer designed to discreetly block unauthorized recordings while maintaining a completely imperceptible operation. With the appearance of a Bluetooth speaker, this device blends seamlessly into any environment, making it difficult to detect. It uses advanced ultrasonic mixing technology combined with a specialized structural design to interfere with the microphones of mobile phones and recorders. As a result, any recorded audio is transformed into unrecoverable noise, effectively protecting conversations from being leaked or processed in post-recording.
Compatible with a wide range of mobile devices and recorders, including Apple, Huawei, Samsung, Xiaomi, and OPPO phones, the MDPB-L107 ensures comprehensive protection against unauthorized recordings across various brands and models. Unlike traditional anti-recording technologies that rely on loud noise suppression, this device employs non-inductive ultrasonic interference, which is barely audible to the human ear while still being picked up by recording devices. This ensures a discreet experience without distracting or alarming nearby individuals.
Additionally, the MDPB-L107 is the first in its industry to adopt acoustic interference rather than electromagnetic interference, eliminating concerns about electromagnetic radiation exposure. The device provides lossless protection for the recording function of microphones without impairing their normal performance. Its easy-to-disguise Bluetooth speaker appearance allows it to be placed inconspicuously in any room, further enhancing its concealment.
Operating the MDPB-L107 is simple and convenient, featuring one-touch control and the option for remote operation. Powered by a built-in 5Ah battery, it offers long-lasting performance, ensuring mobile protection during meetings or private conversations. The absence of any buzzing noise during operation ensures that the device quietly and effectively secures the conversation environment without drawing attention.
This innovative jammer is ideal for corporate meetings, private discussions, or any situation where sensitive information needs to be kept confidential.
